Today Garmin has announced not one, not two, but like 287 watches. Technically speaking they’ve announced two core product series – the Fenix 7 Series, and the Epix series. I mean, ignoring the fact that Garmin previously announced an Epix unit 7 years ago. For the new Epix Gen 2 though, check out my full in-depth review over here. Essentially, the Epix Gen 2 is an AMOLED display version of the Fenix 7, but with still very respectable battery life.

As usual, this watch is a media loaner, and it’ll go back to Garmin shortly. This review is not sponsored (nor does any company get to preview anything I review), and I don’t take any advertiser money from any companies I review. And as regular readers know, if something is crap, I’m gonna tell it brutally like it is – no matter the brand. Once this unit goes back, I’ll go out and get my own for any future testing needs. If you found this review useful, you can use the links at the bottom, or consider becoming a DCR Supporter which makes the site ad-free, while also getting access to a mostly weekly video series behind the scenes of the DCR Cave. And of course, it makes you awesome.

Now, there’s a lot to take in, both in features, but also in decoding Garmin’s wide array of SKUs here. Basically, before even considering color/material combinations there are 8 different Fenix 7 units, plus two Epix units. Including color/material combinations, there are 22 Fenix 7 SKUs. But in short, everything gets boiled down to this:

All units get all software features, and all units get mapping. The difference is that only the Sapphire units have the maps pre-downloaded for your region (e.g. North America, Europe, etc…) – whereas the base & base solar units do not. Instead, you simply connect to WiFi and download what you need for your region (though, that does take a while). That’s because pre-loading all the maps per region would add too many SKUs for Garmin to deal with (since they’d need 4-5 different region models for each model they have, quickly escalating to something like 20-30 additional SKUs to stock).

Now, there are some notable omissions here, especially coming hot on the heels of the Venu 2 Plus release two weeks ago. There is no voice assistance, or speaker/microphone for making/receiving calls. Even more, despite Garmin releasing the FR945 LTE last spring, there’s no LTE edition of the Fenix 7 either – a seemingly bizarre and odd gap. Nor is there an LTE version of the Epix Gen 2 either.

In the case of the microphone/speaker, Garmin says that the higher waterproofing standard of the Fenix series (100 meters) versus the Venu 2 series (50 meters), makes this challenging at this time. On the LTE front, I asked Garmin why there was no LTE option given it’s been a while since they launched the theoretically inferior FR945. It was the singular item they provided a ‘no comment’ on, out of the arguably 50-70 questions/details I’ve asked over the past two months.

Undoubtedly, Garmin will eventually come out with an LTE Fenix/Epix series. Where that’s just an Epix LTE, an Epix Plus LTE, or down the road in a Fenix 8 or Epix V3 (or whatever they call it). I don’t know, but as you’ll see – what’s here today is undeniably cool. But it’s also hard to reconcile this missing bit with one’s purchasing considerations.

Notably missing from that list is the new Stamina and Up Ahead features. Both of which I’d imagine could easily run just fine on Fenix 6 hardware, so it’s a shame to see those not being added. I suppose on the bright side, Garmin does seem to slowly be getting better about adding features to older watches. Baby steps…I guess.

The box for the Fenix 7 series mirrors that of not just the Fenix 6 series, but basically every other Garmin watch in the last half a decade or so. It’s grey and simplistic. While all the box contents for all four units I tested were identical (Fenix 7S/7/7X/Epix), keep in mind that some higher-end fancy-strap editions do have secondary straps in them. I didn’t have any fancy-strap editions. Thus, rather than repeat a series of unboxings, here’s just one sampling:

The band itself can unsnap easily to be swapped out, if you perhaps want a fancier band for non-sport usage, and then quickly swap to the silicone one for sports. They feature the standard Garmin quick release system, and there are three sizes depending on whether it’s the Fenix 7S/7/7X:

There’s also the new button guard on the start/stop button, which Garmin says will reduce accidental starts/stops by jackets or such. It’ll probably take you a day or two to get used to this (at least it did for me), but now I don’t even think about it. Here’s again, a comparison to the Fenix 6 (blue button).

Starting with the hardware, the Garmin Fenix series watches have five buttons, three on the left and two on the right. In general, the upper right button is your confirmation button, and lower right is your back/escape button. The left buttons are for navigating in the menu. And you can long-hold any of the buttons to either access different menu items, or assign quick-access buttons.

Meanwhile, the touchscreen allows you to swipe through and tap menu items just like you would any other touch device. It works reasonably enough while sweaty or in the rain, though precision tends to be slightly less. In general though, as you can see in the video, it’s pretty responsive. Note that no function requires touch, so you can go pure button if you want to. Or inversely, you can get away with mostly touch if you want to (save starting/stopping an activity, and pressing the lap button).

And all of this data is ultimately synced to Garmin Connect where you can dive into days/weeks/months/years worth of data. For example, here’s my steps data on Garmin Connect Mobile (the smartphone app):

In addition to the step tracking, stair tracking, and every other metric is heart rate tracking. This leverages the optical heart rate sensor on the back of the watch. The Fenix 7 uses Garmin’s Elevate V4 sensor that was introduced on the Venu 2 last spring, and is now also on a variety of other watches including the Forerunner 945 LTE.

While not perfect, Garmin has continued to make strides here, and I find generally good correlation in most cases between my perceived energy levels and what it estimates. Just because I went to sleep, doesn’t mean I’ll automatically wake up with 100% Body Battery. In fact, that’s exceptionally rare. Sleep quality will drive how much body battery you wake up with. The scenarios I find it tends to have trouble with are exceptionally hard/long days, or days with exceptionally poor sleep. It’ll usually estimate correctly on the poor sleep, but then has challenges figuring out how to give you a crap score, and then still give you an even crappier score by the end of the day. You can’t go below zero. Still, I think at that point both you and the device are aware of the situation: You feel like crap.

Ok, speaking of sleep, it’ll automatically track that too, and give you detailed information about your exact sleep quality. I’ve been impressed with Garmin’s continued improvements in the written explanations of how your sleep was:

I spent considerable time the last few months comparing side by side a slew of sleep trackers for my Whoop 4.0 and Oura 3.0 reviews, and in general Garmin almost always nailed the time you went to bed and when you woke up. However, it does not track naps in any way, which is unfortunate. Further, I find it can occasionally have trouble with cases where I fall back asleep after being briefly awake between 6-9AM. It’ll often just end my sleep at say 7:10AM if I was awake/up for a couple of minutes, rather than realizing I’ve gone back to bed for 2-3 hours. Note that I have no accuracy opinion on sleep phases, as in general even medical-grade devices aren’t crazy accurate there. Further, there’s often little real-world actionable things you can do based on that.

Now, to briefly touch on Pulse Ox, which is Garmin’s blood oxygen readings. You can configure this to be off, during sleep only, or 24×7. It has two basic purposes in a Garmin wearable, one is around sleep (as potentially an indicator of sleep-related issues), and two in high altitude environments as an indicator that something is about to go horribly wrong. Two totally different use cases (note: medical folks and such also monitor blood oxygen levels too for other reasons). For the first one – sleep – you can track your Pulse Ox readings each night. It’s the red light that’ll light up on the back of the watch.

And that’s the exact same way the FDA certifies blood oxygen medical-grade devices: Sitting still. If you swagger around, you’ll either not get good devices, or, Garmin these days won’t even give a reading. They (and others) have gotten smarter with just giving you a warning that there’s too much movement for a valid result.

During the 2-minute period it’ll measure your heart rate, blood oxygen level, respiration rate, stress, and HRV (heart rate variability). The idea being you can consistently do this, ideally at the same time each day, and start to get a bit of a snapshot of how things are trending. All of these metrics are already tracked by Garmin more deeply in the app/platform, but this aims to put it on a single plate (so to speak). You can then export it into a single PDF if you’d like as well.

As we round home, it’s worthwhile noting that the Fenix 7 and Epix series watches are the first to have the new on-watch app store. This means that you can install Connect IQ apps directly from the wrist, versus having to grab your phone. Garmin outlined this feature last fall as part of the Connect IQ Developer summit. And, as outlined then, it’s pretty darn basic.

Finally, while it probably won’t matter to many people, do note that in general, virtually all of the functions that involve a smartphone require internet to function. Meaning that while the watch will happily collect data without internet, and do so for a very long time, it won’t sync to the phone without internet. That’s because the Garmin Connect smartphone app itself is merely showing data from the Garmin Connect online platform. The exception to this would be if you use the Garmin Explore app (also free), which then does allow syncing of data (namely tracks/routes) back and forth to a phone that doesn’t have internet. And again, this has no impact on viewing any of these stats on your watch itself, but only if you were spending extended periods of time without internet, analyzing your stats on the smartphone Garmin Connect app would not be possible. You can however still plug in your watch to a computer, and download the workout file and analyze that.

This next section is specific to only the Solar editions of the Fenix 7, as only those editions have solar panels in them. Solar capabilities was first introduced on the Fenix 6 series, and then later added to the Garmin Instinct and Enduro series. In the case of the Fenix 6, it added almost negligible battery life for most users. Whereas in the Instinct series in particular, the impact could be quite significant. Keep in mind that while many watches, like Casio, have had solar for years, those watches tend to be super basic in their functionality, and thus in turn, require less power to operate.

The thin stripe around the edge of the display can collect 100% of the sun’s rays. Well, technically it’s of course less than that, but in terms of simple relativity here, we’ll go with that being 100% from a Garmin spec standpoint. Meanwhile, the portion under the glass can only receive 7% – but the surface area of course is massive. Note that the 7% figure is down from a 10% claim on the Fenix 6, which Garmin explains is because Sapphire is normally less clear than regular glass, so by reducing the solar layer, it increases overall clarity (compared to keeping it at 10%). And of course, the under the glass portion (officially called Power Sapphire, now) is the entire display surface.

However, 50K lux actually isn’t super bright. For context, on a mildly sunny day in January in the Netherlands, it’s 10-40K. Similarly, a summer day in the Mediterranean and I’m easily clocking in 100k+ lux. Last week in the Canary Islands off the coast of Africa, I ranged from 60K to 150K in the sun (mostly in the 60-100K range). All of Garmin’s figures for battery assume 3 hours a day at 50K. So in the winter that might be tough for folks, whereas in the summer on vacation, that’s probably trivial. Garmin notes that if you go beyond the 50K conditions, it’ll leverage that power – even though the icon itself won’t show more than the full sun indicator.

As you can see, it’s quite significant – again, assuming you have the solar power. But this is only showing that 3 hours. So imagine you’re hiking in the summer across a mountain range. In that case, you’ll likely have both far more than 3 hours a day in the sun, and depending on the weather, you’ll also have way more than 50K lux conditions. Garmin says that in none of these scenarios are they claiming ‘forever power’, but the reality is, if you turn off certain features, then you can basically get there with even just a few more hours of summer sun conditions. Inversely, if you’re hammering offline music + multiband GPS in a winter snowstorm with the optical HR sensor enabled doing PulseOx 24×7, then solar isn’t gonna net you much.

Next there’s the running mode. In this mode, it’ll automatically flash the white light for when your arm is forward, and the red light for when you’re arm is backwards. Here’s the visual theory, from Garmin:

Hopefully, we’ll see this feature expand to the rest of the Fenix series in the Fenix 8. Or, to other Garmin watches. As with every Fenix series, the ‘X’ variant (e.g. Fenix 7X) always gets some new experimental feature first, and in the case of the Fenix 7 series, that’s the flashlight.

There’s literally no watch on this planet that has as many sports features built-in as the Garmin Fenix 7 series does. I don’t think that even if you downloaded every app on the Apple Watch store that you could cobble together every last nuanced sport and fitness feature. Of course, as always, that’s largely been Garmin’s thing in life: A gazillion features, of which you might only use 2-5% of them.

You can customize this sport listing on the watch, or from the smartphone. In fact, now’s a good time to talk about that new phone-based configuration. This is the first time we’ve seen Garmin introduce this level of customization from the phone. You can tweak almost every setting on the Fenix 7 from the phone. Be it sport/activity profiles, data fields/pages, or things like widgets or deeper system settings. There’s only a handful of things that must be done from the watch – for example downloading maps, or adding new sensors. As with before, you can always change all the settings on the watch itself if you want – handy when you’re out on the trails without a phone.

A good example of where Garmin seems half-way on this is the Sensors & Accessories section. You can see here that you can tweak all the onboard sensors (like whether or not your heart rate broadcasts), but you can’t pair any external sensors from the phone, you’ve gotta go to the watch. I’d imagine over time these will converge.

I actually don’t mind that this is clearly a V1 of phone-based settings. I’ve argued for years that Garmin needed to stop trying to boil the ocean on this, and instead, just start somewhere. Anywhere! Forget the past, pick a newly launching watch and add phone-based configuration. Start small and build up. For example, you can’t import/migrate settings from other devices (like you can on a Garmin Edge device). And similarly, for the most part, the settings here just feel like Garmin built all the plumbing, but it’s sorta a maze of depths to find them all. But again, for now, I’m good with that. Boiling the ocean never works, perfection is the enemy of progress. I’d rather progress.

Once you’ve got your settings sorted, head back to the watch and pick said sport. In my case I’ll pick a run. Of course, sports have different profiles for a slew of reasons. Those can be specific data fields for a sport (like strokes for paddling, or cadence for cycling), as well as sport-specific calorie burn, or the sensor types which they connect to. On this page here you’ll see the upper portion of the page showing the current sensor status, as well as GPS status. Your data pages are displayed behind it.

If you tap the up button you can add a course (or other routing, more on that later), structured training, or change the power profiles. I mean, frankly, you can change anything from this point. For example, you can see how many hours of GPS life you’ll get with your current settings, and then there’s some pre-canned options which show higher GPS levels if you realize you’ll need them. Or, you can go rogue and create your own battery profile:

Notably absent though is there’s no wrist-based running power like COROS and Polar have. If you want running power, you’ll need some sort of external sensor – either from a 3rd party (Stryd), or paired with Garmin’s HRM-RUN, HRM-TRI, HRM-PRO, or RD-Pod units – for Garmin’s own running power data field. Nothing has changed there.

Here’s a chart (it shows this later in Garmin Connect, both mobile and desktop), showing this workout of 800’s and how it played out. In some cases, the interval wasn’t as impactful – such as those last two longer ones, largely because I was struggling to hold the same intensity levels (HR’s).

Next, going back to that interval workout, there’s a new feature that shows up on Garmin Connect afterwards, which is walk/run/stand detection. This will automatically detect, during a workout, what you were doing. You can see how that looks here:

This actually does then auto-categorize the interval run times and paces – if you check out the gallery of screenshots from Garmin Connect, it has a line item called “interval run pace”, so that’s kinda neat.

This is one of those things that at first glance didn’t make a ton of sense to me. I mean, yes, it was spot-on accurate, but why bother to spend the time on this was quirky to me. In asking Garmin, they said the intention was that for certain racing/training, such as steeper incline training, it allowed folks to start to analyze whether or not the pace/HR tradeoffs were worth it on walking versus running. Since you can overlay all those stats atop it, I can see the logic there.

As usual, all your workout stats can then be displayed on Garmin Connect or the smartphone app (Garmin Connect Mobile). Here’s a slate of those screenshots as a sampler:

From a sports standpoint, every workout you do is being tracked from a training load standpoint. You’ll have seen how that given workout contributes to your load in the workout summary screens above. There’s both a specific training load value (e.g 110), but also a given training effect focus, such as base or VO2Max. These all get worked into whether or not your training is productive, and if not, what you’re doing wrong. You can see this from the widgets menu quickly:

I think in general, as much as it pains most of us endurance athletes to admit this, Garmin is usually right here. When it says I’m short in a given category, the reality is that if a coach had laid out the plan, it’d have been more balanced than my ad-hoc workouts.

I’ve long found that Garmin tends to overshoot here. Nonetheless, there’s also some misunderstanding on this from many users. This item isn’t actually saying not to train, it’s saying not to go out and do a hard workout. Thus, within the context it’s usually not too bad, though I think it still tends to err on the side of keeping you healthier rather than pushing your body closer to the breaking point.

These workouts can be downright beastly when Garmin chooses to get spicy. Seriously, I’ve seen multi-hour interval workouts show up. Inversely, if you’ve had a hard few days of training, or, really poor sleep, it’ll simply tell you to rest. In fact, if you really get it upset, it’ll actually flash a warning to you mid-morning that your day isn’t going well and that it’s going to basically cancel your planned workout. In general, I’ve found that when the watch gets this upset, it’s almost always legit. Usually something like back-to-back poor sleep combined with a hard workout tossed in the day prior, and maybe showing high stress.

In any event, if you do go ahead and choose a workout, it’ll iterate through each step with the exact targets displayed on the screen in real-time. None of this has changed from how it works on past Garmin watches over the last decade or so.

First up is the new map manager feature. Up until now, when you bought a Fenix series device, it included the maps for your region (e.g. North America or Europe), but not other regions. For that you either had to pay $20-$30 to download maps from Garmin (which was cumbersome, at best, using a desktop computer), or, you had to download similar free maps – which was also cumbersome. But the new map manager makes it all free, and directly on the watch.

Downloading takes a long-ass time. To download the TopoActive Europe map (11.6GB), I timed it at somewhere between 4 and 4.5 hours (I went to bed at 4hrs with it at 90%). Seriously. You can alternatively use Garmin Express on a computer, which tends to be a crapton faster, since it’s transferring USB. Remember that in general the watch uses a lower-power consuming WiFi chipset, so it’s not downloading things as fast as a phone or computer. In other words, do this the night before you leave for a trip, and let it sync overnight. Or, let it sync while you make a 12-course dinner or something.

Note, that in February (a month after this review went live), Garmin has now split it out into three different regions, to allow you to pick just one region, saving you space – especially notable for non-Sapphire SKU’s. This is only available when using a computer with Garmin Express, though, that’s massively faster than WiFi (most of these took less than 10-15 mins for me to download, compared with hours on WiFi, since the Fenix/Epix units don’t have very fast WiFi connectivity).

Ok, with the maps downloaded, let’s set out on an adventure. In today’s case, I’m using a route created on Komoot. But you can also create routes in Garmin Connect directly, or other 3rd party apps or files. For example, if you have a GPX/TCX/FIT file of a route, you can import them in. The easiest thing to do is import them into Garmin Connect, which then allows you to sync them to the watch. But, to show you the new Up Ahead feature, I need to use Garmin Connect to tag the waypoints with standardized icons. So I’ve imported this Komoot route to Garmin connect:

Now, I’m going to add a few waypoints here. Waypoints in files of course aren’t new. They’ve been around for a decade or two. In this case, Garmin calls them Course Points, but it’s effectively the same. You can tap on your route and add these points from a list of about 50 different standardized icons.

Continue doing that till you’re done. Garmin says that they’ll soon support enumeration within Up Ahead (explainer in a second) from 3rd party files. But in the meantime, you need to use either Garmin Connect or Garmin Connect Mobile to tag these locations.

With that set, we’ll get out to the trail and load up the course. You can choose any GPS sport mode you want (hiking in my case), and then from there choose Navigation and Courses. This allows me to load up my course. When I do so I’ll see map options, elevation, as well as ClimbPro. Note that ClimbPro isn’t enabled by default on all sport profiles, so you may want to enable that within the sport settings (I do – it’s one of my favorite features).

It’s simple. This isn’t some crazy complex feature. And in fact, it’s roughly like what COROS added for navigation. The difference is a bit more polish. Garmin added standardized icons, and the fact that you can easily glance at it on a single page, versus having to scroll through a list.  No matter who does it, I found this incredibly helpful on my recent hikes. Mainly just for quick context. The distance is, as expected, using the course route.

One thing that’s grown on me as more annoying is the lack of arrows or chevrons on the Fenix series routes. Garmin added arrows for the route direction on the Edge series this past year, like many other vendors have had for years. While this doesn’t matter for many course that are clear-cut, it does matter for courses that may intersect, like a figure-8 course I did on Thursday. In that case, when I got to the crossing point, I tried to decipher which way to go, but Garmin wasn’t clear. In fact, it seemed to tell me to go one way, but as I’d learn some time later – that was the wrong way. Unfortunately, because I was technically on the course, I never received an off-course warning. As such, ClimbPro was also broken because it kept thinking I’d be turning around going the other way.

Now again, I’ve also gone years without this functionality, but it seems time to at least have the option for arrows. After all, Garmin has approximately 9,238 other routing-related options. In any event, that largely self-owned failure aside, I’ve had no issues with navigation across a wide variety of hikes, runs, and bikes over the last 6-7 weeks.

The Fenix 7 contains virtually identical features to the Fenix 6 series in terms of both music and contactless payments. Meaning that these features are basically the same across all Garmin watches. In order to play music, you’ll need to pair up some sort of Bluetooth headphones or Bluetooth speaker. Then, you can download music and play offline Spotify, Deezer, Amazon Music, as well as any of your own MP3s. Meanwhile, on the contactless payments side, that continues with Garmin Pay, where you can load your bank cards – assuming they’re supported. These days, the biggest banks in the US and many other countries are supported though.

You can also use Spotify to download podcasts, which is a handy way of doing it versus the regular Garmin podcast feature that requires a computer to sync the podcasts. With all music streaming services it’ll leverage WiFi for the music sync. In general, the simple math is about 5-10 seconds per song to download (so about 10 songs per minute (speed varies based on the length of the song and other factors. You’ll just choose which playlists you want, and then it’ll go off and download them. As long as the Spotify app checks in once per 30 days, your music stays valid.

I haven’t had any skips or dropouts in either casual listening to music at my desk, or in workouts using the Beats Studio Buds. I’m not a huge listening to music while working out person though, but I find in general these days Garmin and others seem to have compatibility with headphones pretty well sorted out (compared to devices from a few years ago being some of the first generations to have wearable music support, and often had connectivity issues).

Now, switching gears a bit you’ve got contactless payments. These use NFC, and in Garmin’s case their payment platform is called Garmin Pay. It’s essentially no different than Apple Pay or other payment platforms, and is generally supported anywhere you go as long as the card itself is supported by that merchant. And in fact, that’ll likely be your main limiter in terms of usage: Whether or not your credit card is supported.

For this, you’ll need your bank to be supported by Garmin. That’s many of the big banks in the US, but beyond that it varies quite a bit. It’s hit or miss. A full list is here.

In my case, my Netherlands bank (ING) isn’t supported (still). However, my US Visa credit cards (Chase) are supported. My French Bank account (HSBC) isn’t supported, nor are some of my US local banks. Ultimately, this requires Garmin going to every single bank worldwide and get them onboarded. It’s not just a blank Visa/AMEX/Mastercard type thing. Hence why it’s hit or miss.

While you won’t get any payment receipt on the watch, you can see it later in the Garmin Connect app under ‘Recent transactions’ within the Garmin Pay details.

I had considered placing this section within the GPS accuracy section, or perhaps within the sport section. But both were already pretty long. So consider this a shorter primer to a slate of changes Garmin has made. There’s actually more than just the addition of dual-frequency (multi-band) GPS here. Garmin has also revamped pretty significantly both its base GPS mode for big battery life savings, as well as gotten rid of the GLONASS/GALILEO options. Sorta.

First up though, let’s explain what multi-band GPS is. At a non-technical level, it’s been touted as the holy grail of GPS accuracy. But technically, GPS is the wrong word. That’s because GPS is actually a ‘brand’, whereas this is officially just an umbrella of GNSS’s (Global Navigation Satellite System). But we’ll set aside the Kleenex argument for the moment. The theory behind dual-frequency GPS is that you can connect across two different frequencies to the satellites, thus if one frequency is having connection or visibility troubles this would mitigate that by providing not just a secondary frequency to validate against (L5), but a frequency that’s 10X greater. Thus, instead of perhaps 20-25 satellites, there’s now upwards of 60+ satellites your watch can see. And by seeing more satellites in addition to increasing the signal and varying the frequency, it allows your watch to better mitigate signal obstructions and increase accuracy.

Garmin is hardly the first company here in this space. While Garmin did roll-out multi-band GPS to some of their hand-held devices a year ago, the Fenix 7 & Epix are the first wearables to have it (despite rumors to the contrary, Garmin says the Tactix Delta nor any other wearable from them had multiband prior to this). In any case, the first endurance sports watch to add it was the COROS Vertix 2 this past summer, and then more recently Huawei has touted it in their GT 3. In my testing of the COROS Vertix 2, I didn’t see holy-grail-like results. It wasn’t bad, but it wasn’t the promised land either. Of course, the tech is new, and thus we’re likely to see (and have seen) firmware updates rapidly that’ll improve that. More on that in a minute. In the case of COROS, they’re using the MediaTek/Airoha chipset (AG3335M), and Garmin confirmed they are also using Airoha as their supplier. Prior to confirmation from Garmin, this made sense in my testing, as in almost every scenario over the last 6-7 weeks, the Vertix 2 and Epix/Fenix 7 units made the exact same errors in virtually identical ways (and inversely, did things correctly in near-identical ways). Garmin also confirmed that both Sapphire and Non-Sapphire units across all Fenix 7 and Epix units are using the same chipset supplier (Airoha).

So the idea being that you can perhaps use higher-level dual-band accuracy on an openwater swim or a mountain bike ride through difficult terrain, but then go with less-battery-draining options for a road bike ride, which is typically one of the easier things to track GPS-wise.

GPS Only: This is the base GPS-only option, however, Garmin says they’ve drastically increased the battery life here compared to the past GPS-only option, and indeed, you can see that in the battery chart.

All Systems: This confusingly named option is dealers choice between GLONASS and GALILEO, and Garmin is the dealer. As a user you can’t choose which one to use, but instead, Garmin is now switching between GPS< GLONASS, GALILEO, BeiDou, and QZSS based on the quality of the satellites from each, determining “which to prioritize”

UltraTrac: This setting is for crazy-long adventures, whereby it reduces the GPS update rate significantly. Do not ever use this setting unless you absolutely need it, you’re GPS tracks won’t be pretty. Think of this as the emergency option.

Note that the usual smart-recording or 1-second recording option is still in the settings (and still annoying defaulted to ‘Smart Recording’), but that has no bearing on the GPS reception timing/display, it’s purely what it writes to the recorded file.

One thing to keep in mind is that Garmin does track vastly more health stats behind the scenes that COROS does and at a higher rate too, which certainly has a big battery drain component. You can turn off some of these though, which would increase the battery life further on the Garmin.

Though, the GPS battery life one-upmanship is quirky. From a sport standpoint is largely only impacts the upper tier of Ultra competitors. However, from a practical day-to-day standpoint it simply means you charge your watch less frequently.

There’s likely no topic that stirs as much discussion and passion as GPS or heart rate accuracy.  A watch could fall apart and give you dire electrical shocks while doing so, but if it shows you on the wrong side of the road?  Oh hell no, bring on the fury of the internet!

GPS accuracy can be looked at in a number of different ways, but I prefer to look at it using a number of devices in real-world scenarios across a vast number of activities.  I use 2-6 other devices at once, trying to get a clear picture of how a given set of devices handles conditions on a certain day.  Conditions include everything from tree/building cover to weather.

Over the years, I’ve continued to tweak my GPS testing methodology.  For example, I don’t place two units next to each other on my wrists, as that can impact signal. Instead, I’ll often carry other units by the straps, or attach them to the shoulder straps of my hydration pack or backpack.  Plus, wearing multiple watches on the same wrist is well known to impact optical HR accuracy.

So, we’re going to start with a feast of watches on a route that’s both easy and extremely challenging. I start off along some canals and farms, and then eventually wind my way down through a long skinny street of 12-18 story buildings on both sides. For this test I had the Fenix 7S on my left wrist, and the Fenix 7X on my right wrist. Then, in each hand I was carrying a COROS Vertix 2 (right hand), and an Epix (left hand), plus also a FR745 in the right hand. All these were separated and stable, as to not impact each other. I carry them the exact same way companies themselves do GPS testing:

So, here’s that data set, and at a high level, things look pretty similar. All Fenix 7/Epix/Vertix 2 units were set for multiband GPS, and the FR745 was set for GPS+GLONASS. All the units had no problems in the openness sections:

However, as we approached the first set of light buildings and bridges, the impact of multiband GPS became apparent, with those units plotting slightly clearer tracks. For example, the FR745 in pink turns way too early under the bridges, whereas the rest got it right.

I’d also see some minor differences between the COROS Vertix 2 and Garmin units. For example, here the COROS Vertix 2 incorrectly gets frisky while going under a tunnel, sharply meandering off to the side. However, a short bit later, the Fenix 7X then did some less sharp but longer bushwhacking away from the path. Which is interesting because in general I saw that most of the time if the Vertix 2 made an error, then the Fenix 7 and Epix repeated it.

Fast-forwarding into the downtown sections with tall buildings on both sides, we can very clearly see the FR745 struggles slightly more here, it’s the unit without multiband. Which however, isn’t to say it was horrific, nor to say that the others were perfect. The multi-band ones were simply a *TINY* bit better. But all the units traded having GPS tracks that blasted through the sides of buildings. Let’s be clear about that, this isn’t some holy grail we hoped for (just as it wasn’t and still isn’t on the Vertix 2).

Next, let’s head into the jungle for a hike/trail run. This one had it all! From deep woods, to dense trees, and towering cliffs. Here I was comparing the Garmin Epix on my left wrist, the Fenix 7 on my right wrist, plus both a COROS Vertix 2 (right hand) and a Forerunner 745 (hydration pack).

And as you get into the weeds, literally, of the jungle, it’s hard to see much difference. Meaning that the three units are nearly identical in every scenario (within 1-2 meters of each other, wobbling along), except that the COROS seems very slightly more smoothed. That has pros and cons. The benefit is that it tends to clean-up the GPS tracks a little bit in tougher areas, but the downside is that it also incorrectly cuts some corners and such that you actually hiked – as it doesn’t seem to be 100% certain between a short switchback for a couple of meters, and a GPS error.

I’m not saying Garmin is right here, but I am saying that based on all my test data both over the last 6-7 weeks, but also from this past summer/fall with the COROS Vertix 2 and multiband, that it tends to over smooth in areas where the going gets tough. That in turn tends to result in lower overall distances. On a tree-dense route like this, or frankly, any ultra route, it’d be nearly impossible to know the exact actual distance you went. Even a measured trail course isn’t going to know whether you took each corner a foot or two wider (which would add up considerably over a longer route).

It is also true that both the COROS Vertix 2 and Garmin Epix/Fenix 7 units in multiband, outperformed the FR745 (using just GLONASS). One can see that in numerous occasions. However, keep in mind that extra unit was largely on my backpack shoulder strap, which has body-blockage effects.

All of this is spot on. However, it’s not as if they’re on the correct side of the road (or consistently on any given side of the road). So that’s where we need to park the Holy Grail GPS Bus, and remember that hasn’t arrived yet:

Then we’ve got an openwater swim. This is pretty impressive for both Epix & Fenix 7, though we see slight differences. For example, the Fenix 7 seems very slightly more smoothed than the Epix, though, it’s not clear why as both were on identical settings. My guess here would be this is actually a stroke difference in how high up my right hand/wrist goes compared to my left wrist, which could definitely have a slight impact. But still, there are astoundingly close GPS tracks here to the reference units on the swim buoy.

Here’s another openwater swim, this time directly comparing the Epix to the COROS Vertix 2 on opposite wrists. Sure, no Fenix 7 here, as I only want one unit per wrist. You can see the Vertix 2 is slightly more wobbly, and the Epix also overshot very slightly on the corner. Though, this was also a month ago, so things have undoubtedly changed in GPS performance (as we see above):

No matter which sets I pull up on the Epix or Fenix 7/7S/7Xfrom the last 6-7 weeks, the overall GPS tracks look very good. Are they absolutely perfect? No, but they’re on par or better than anything else I’ve seen lately. And as I alluded to elsewhere, I thought it was interesting that if I compare the most recent Vertix 2 tracks to the most recent Epix/Fenix 7 tracks, they’re nearly identical in many cases. Both making the same errors and non-errors at the same time when worn together on workouts. The only difference being that it appears COROS applies slightly more smoothing in a variety of situations, which has the previously outlined pros and cons.

(Note: All of the charts in these accuracy portions were created using the DCR Analyzer tool.  It allows you to compare power meters/trainers, heart rate, cadence, speed/pace, running power, GPS tracks and plenty more. You can use it as well for your own gadget comparisons, more details here.)

Meanwhile, for HR accuracy testing I’m typically wearing a chest strap (either the Polar H10 or the Garmin HRM-PRO), as well as another optical HR sensor watch on the bicep (mostly the Polar Verity Sense, as well as the Whoop 4.0 band). Note that the numbers you see in the upper right corner of the charts below are *not* the averages, but rather just the exact point my mouse is sitting over.  Note all this data is analyzed using the DCR Analyzer, details here.

I go through everything from real-world side-by-side battery life on long workouts, to how the screens differ in real-life usage, plus aspects like map differences, graphing details, and more. It’s more than just the display! You can find the full Fenix 7 vs Epix post here.

Virtually every aspect of the Fenix 7 is better than the Fenix 6 in my testing. Both the tangible things like GPS, barometric altimeter, and heart rate accuracy – but also much of the day-to-day bits around user interface design is more polished. Or even seemingly minor things like the button guards (though, those do take a day or two to get used to). Tasks that used to be a headache, like loading maps ahead of a trip, are now trivial. And for those 7X owners, the ability to light your way through an unknown hotel room in the middle of the night is handy. Plus the myriad of other sport-focused uses for the flashlight.

In terms of stability and reliability, it’s been very solid for me overall. As noted, almost all of my workouts had very strong heart rate accuracy, with only a singular hard interval set going askew in colder weather. On GPS, I had no major failures, or really even minor failures – as seen in all the sets above. It was as expected/good, and in some cases really good. Software-wise I’ve had no problems on this final firmware version that the unit is now shipping with (any previous bugs were on beta firmware).

As I sit here typing this on my laptop, I’ve got Epix on my left wrist and the Fenix 7 Sapphire Solar on my right wrist. And there’s simply no comparison in the display. Even with the Epix display automatically dimmed because my wrist isn’t facing me, it’s still easier to see than the Fenix 7 on my other wrist. Of course, this Epix lacks ultra-long battery life, either in standby watch mode or GPS mode. But frankly, I just don’t need that. Sure – I’d *like that* if it could be with an Epix display, but I’m very consistently getting 6 days of Epix battery life over the last 5-6 weeks. That’s in always-on display mode with roughly an hour of workouts per day (and usually longer on weekends). A blend of GPS and non-GPS.
