If you've always wanted to be a fitness cyborg...

First things first: the Garmin fenix 3 isn't a watch. Yeah, it will tell you what time it is, and what day it is, and it will wake you up in the morning, but so will your little cousin Marcus. No, the fenix 3 is a high-powered wearable computer for runners, hikers, cyclists, swimmers, skiers, snowboarders, mountaineers, endurance athletes, fitness freaks, and anyone else who wants to have an almost limitless amount on information at their fingertips—er, on their wrists—wherever they are. And unless you tell someone how nuts it is, they won't even know you're wearing anything other than a normal watch. That's because the fenix 3 looks just like a stylish but normal watch, with its stainless steel housing, rubber band, and hardened crystal face keeping the digital display safe and sound.

The thing is, that stainless steel housing conceals an EXO+ GPS and GLONASS antenna that's the basis for all the location-marking, activity-tracking, and route-planning capabilities of the fenix 3. It can tell you how fast you're going, how far you've gone, where you are, where you're going, when you'll get there, how fast your heart's beating, how many calories you've burned, how much elevation you've gained, what type of swimming stroke you're doing, how many ski runs you've taken, how soundly you're sleeping, and literally dozens of other things that would take too much time to list. It can even come up with a digital partner for you to race against, let you race against yourself, or let you see how much faster you bike than run the same course.

Once it has tracked all of these things, it can save them or automatically share them with your phone, tablet, or computer, so you can see what you've done, the progress you've made, and start planning for the future. Among other things, it is compatible with ANT+, which lets your tracking devices talk to each other and share even more data. It has various heart rate monitors, and Garmin's tempe thermometer. You can even get email, text, and stock alerts while you're on the move, if you can't stand be disconnected even when you're in the wilderness. No matter how you slice it, the fenix 3 is a powerful piece of wearable tech that has the ability to totally change how you work out, recreate, compete, and explore.

Great gift!

    I bought this as a birthday gift and he hasn't taken it off since. It is larger, so expect it to be slightly bulky if you have a slight build, which also gives the display great readability. All functionality seems to be accurate except for the temperature because the sensor is too close to your skin. Other than that, the watch goes from the office to the mountains perfectly!

    Never take it off!

    • Familiarity: I've put it through the wringer

    This is the best watch I've ever owned. All the features of a smart watch with full gps, activity tracking, and two weeks battery easy.

    Buy it. Don't look back.

    Never take it off!

    Great watch

      Without calibration, it was only off by 56 feet. Bulky?..of course! It's a GPS watch.

      Great watch

      Does everything I need

      • Familiarity: I've used it several times

      This is an awesome watch, I honestly haven't used even 2/3 of the functions, but I am a fan of what I have utilized. The only reason I didn't give it 5 stars is because it's a little big and bulky on my wrist.

      Great Watch

      • Fit: True to size

      This is an awesome watch. I love having the GPS and all other tracking right on my wrist. A little complicated to use at first, but playing around with it and reading the instructions made a big difference and now it's second nature. Might be a bit big on some smaller wrists, but it fits me great.

      Awesome Watch

      • Familiarity: I've used it several times

      Altimeter, barometer, GPS tracking, and activity tracking, reliably, all on my wrist? Yes please! This watch is awesome. The Garmin Connect lets me hook up my data to Strava and red band is super fancy. One downside - its not the smallest watch on the market.

      Adventurer Racer

        Awesome watch, really glad I invested in it. Stock watch band was actually really impressive, and can't beat the Live Tracking feature that allows your loved ones or friends to check your progress during those day long races. I only find myself charging my Fenix 3 once a week, which isn't bad at all. Great fit and look.

        not for skiers

          I bought this watch for skiing. Although I really wanted to love it, and I can tell that it is a good product for some sports, it does not do what I wanted.

          First, I wanted to be able to track my skiing by the day and by the run. This watch automatically stops the timer (and the "climb") when you are on the chair. While this may desirable for some, I have always tracked my ski days as a total, not just the times I was descending.

          At the end of the day, I want to look at my stats, runs etc. The information given on the "Connect" app is for time and distance per run, no elevation information! Yes, I can find this info on the watch, but why have a skiing app that does not give vertical? Kind of a joke.

          But here is the deal -breaker for my - well two of them. If I am going to spend this kind of bread on a watch, I want it to work for my fitness goals. And mine are based on vertical feet skiing. So I went to the "training" app to set a target- What? I cannot set a vertical feet, or descent target? Okay, well I will just use the odometer feature and track day to day myself, "manually". What, no vertical descent odometer? Okay, well I will just use the climb odometer, because chair skiing I guess descent and climb are the same. What? It does not record climb on the skiing app, because that is turned off with the "auto-run" feature on. Okay, I will turn that feature off. What? Now it does not keep track of runs?

          You can keep track of distance, which for skiing is a joke; the easier the run, the longer the distance for the same vertical drop. So "distance" is relevant only if you are trying to NOT get in shape.

          $500 and I cannot use it for skiing? I am taking it back. Very disappointed. I wanted to love this watch and geek out with it for years to come. Turned out to just be a big time suck trying to figure out why it wouldn't do what a skier would want it to do.

          • Familiarity: I've put it through the wringer

          My old Garmin forerunner died and the stressful quest began to find the replacement. I like to have 1 GPS for running, biking, skiing, hiking and all things fun. Its primary purpose is for my long training runs and 100 mile trail runs and it has exceeded my expectations.

          Being able to down load apps and set the display to something I like is fun, navigating the menu is simple and the buttons are easy to find even after no sleep for 24 hours.

          While the Garmin doesn't have enough batter life to use the GPS for a full 100 miles (at least for most of us), you can charge it on the go using a Goal Zero Flip 10 recharger, you have the Garmin charger cord to deal with, but just for a couple of hours and then you are good to go for another 12-14 h. I'm not one that likes or needs to be connected to my phone 24/7, however, I have to admit that being able to run or mtn bike with my phone in my pack and receive text messages and see who is calling without having to stop, this has turned into a value added feature. While this was purchased for use with activities, I have found myself wearing this everyday since it reminds me when I have been sitting too long at my desk with a message to 'MOVE', I can't argue with that!

          Geek out or not - great watch

          • Familiarity: I've put it through the wringer

          Upgraded from the Fenix to Fenix 3 and haven't looked back. If you are a geek then this watch will give you a lot of data to pour over. I'm not a geek, but still love the user friendliness of this watch to customize screens and even download unique faces and parameters from the internet. Veddy Cool.

          For the "Jack-of-all-trades" this is THE watch. I trail run, whitewater kayak, backpack, mountain bike, flyfish in saltwater marshes and the list goes on. For gym rats you can even measure your spin class stuff or treadmill crap (ugh).

          If you are only a runner or tri-athlete this isn't the watch for you, but if you engage in a LOT of various outdoors activities this watch will meet your needs.

          My ONLY complaint is that mt biking in the thick woods it doesn't mark distances super accurately. Running doesn't seem to be a problem and maybe this is something Garmin can fix with an update.

          Go out and get it done - on the trails, on the road, in the woods, in the marsh. This watch will serve you and all those pursuits well.


          Addendum: 1/20/16-- I was having issues with my Fenix 3 reliability on distance. I called Garmin and they verified I had updated the firmware and THEY suggested they send me a new device! I did not have to press them at all - great customer service. New watch is in and will test it and comment when I get a few runs/mt bike trips/etc behind me to weigh in, but I feel like based on the conversation with the CSR at Garmin that there was an issue with my device.
          Great Service Garmin.

          What are the differences in the Fenix Models?

          Best Answer

          So there are actually a lot of differences, maybe to many to hit up here in this forum. First off, lets drop the Fenix out of the equation, its the same price as the updated 2, and Garmin doesnt make/ sell it anymore.

          Fenix 2 versus Fenix Bundle = HR monitor. Extra $50 gets you the heart monitor included in the box.

          Fenix 3 slightly bigger face yet, thinner on the wrist. Better display resolution, and had color display. Weigh .01 oz less than the Fenix 2. Smaller battery means its faster to charge yet, it holds the same power as the 2 and even an extra week when only in watch mode (No GPS). You can also have some functionality between music on your phone and a find your phone feature. A big seller is the Fenix 3 uses, GLONASS an additional GPS system that provides more accurate and faster (20% faster) satellite data, than a device with out.

          Some other features is that it will keep your personal records and provide a virtual pacer for you. Comes with a step counter, and actually monitors sleep patterns. It will also easily auto syn data to your computer.

          The one thing it does not come with is the hunting/fishing calendars, and the sun and moon info.

          I think the GLONASS alone is worth the extra $100 plus you have the latest and greatest from Garmin.

          backpackers dream

          • Familiarity: I've put it through the wringer

          I have to say as a suunto fan I was hesitant to get this watch. However after using it for some time I'm glad I made the switch. Suunto makes great watched but they are more geared to the ultra sport crowd. I love pizza too much to be running, biking, and swimming all in one day. However my passion is backpacking. the accuracy of this watch is amazing. Compared to my other watches including the suunto ambit 3 the fenix 3 was closer to not only my location but altitude and pace. I lost most of my hearing when I was in the Army, (my fault for being to close to stuff that goes boom) so i have a very hard time hearing the alarms on most watches. Having the ability to set a vibrate alarm to notify me of a planned stoping point or wake up time was a huge plus. Also the ability to change the settings on the watch is nice, some make you connect to a computer to do so. Lastly i use a powermonkey solar charger and noticed the watch takes to battery and solar charging very well unlike the older garmin and suunto models that liked to throw a fit when you used anything but a wall outlet. Its a bit pricy but this watch will give suunto a run for their money.
