Rated 1 out of 5 by from Horrible GPS Performance for Trail Running I so much wanted to like the Fenix3. It's a great-looking watch with every feature and function you could want. Unfortunately, it fails miserably in the most critical way: its GPS tracks are horribly inaccurate, at least for trail running. The performance is okay (not great) for road running, cycling, etc., but throw in heavy tree cover, lots of switchbacks, and altitude changes and the watch just goes bonkers. As a test, I wore both the Fenix3 and my older Ambit2 R on a recent 3-loop trail run (on different wrists to avoid mutual interference). The Fenix3 was running firmware version 3.6 which Garmin released expressly to "fix" the GPS issues. Here are the tracks from the Suunto and Garmin web services. Suunto is on the left (and it shows the correct track for the 3-loop run). The difference is clear, and the Fenix3 is simply unusable.

Rated 5 out of 5 by from Great for running and other sports For the past 6 years I had been running with the Garmin 405CX and before that the Garmin 305. I kept waiting for years for the right model to come along for my next upgrade. I bought the Fenix 3 with the Heart Rate Monitor from REI online and am really happy with my purchase. I haven't had any of the connectivity or software issues mentioned in the negative reviews. To the contrary everything has been working great. Not only is this super easy to use, but satellite acquisition time is so much faster. I use it for running, hiking, and cycling and in the winter will use it for winter sports. If you're a serious runner, and like other sports as well, this watch is amazing.

Rated 4 out of 5 by from Great watch! I've been using the watch for a couple weeks. While using Bluetooth connected to my iphone to get notifications, txt messages, ect, it loses about 10% of battery life a day. I've done several bike rides and runs with GPS and the battery life seems to be a good as stated. I've been checking the barometer against the national weather service for my location and it is spot on. .01 difference when checking. So far I've had no issues with the firmware (3.1), software and my phone or computers. The only reason I don't give it 5 stars is for two reasons. 1- The temperature gage is thrown off by the users body temperature. 2 - Even after calibration and because the barometer is tied to the altimeter, the altimeter is way off within 24 hours. These seem to be the two areas no watch maker has been able to successfully tackle. Still an awesome watch.

Rated 5 out of 5 by from So far I love it. I have only had this watch for a couple of weeks so far but I love it. I have wrists a little larger so as an all day wear it works well but it might feel bulky to someone with smaller wrists. The information from the HRM is outstanding. I never realized how poorly I was running. With the help of the metrics I have notice my runs actually getting easier. One thing, if you don't get the sapphire and plan on wearing it all the time I would definitely suggest looking into a screen protector. I find due to the size (or my not paying attention) that I know I it on things a lot and due to that the screen could start scratching.

Rated 2 out of 5 by from Great potential and features, terrible GPS I wanted this watch since it was announced and as soon as rei listed it I bought it as a birthday gift to me. Happy birthday to me. But the more I used the watch the more disappointed I got with one particular area of the device. It's got a terrible gps the $60 motoactv it replaced was much more accurate. The Fenix routinely drops the signal on the rail trail and will record 1/2 mile and at times 1 mile off on a 22 mile run. I used the watch on the Vermont City Marathon and it failed terribly at tracking my pace. I returned my garmin fenix 3 and went back to my motoactv for now. I loved every other feature of the watch because it's a great watch. So I'll buy it again if they fix the gps that's the most important feature of a gps watch!

Rated 1 out of 5 by from Nice Watch, HORRIBLE GPS! I love so many things about this watch, but I have returned it because the GPS performance is so substandard. Tree covered trails are the worst. Compared to my other Garmin products, a 310xt watch and etrex30, and also an Iphone, this watch consistently measures 5-10% short in those conditions. The track is crazy compared to the other, ( cheaper ) devices. In the open, staight courses, easy GPS conditions, it's better and usually distance is fairly close to other devices, but even then, when I compare tracks it's obvious the Fenix 3 is the worst of the bunch. Hopefully, they'll find a way to fix that. If they do, I may repurchase, it's a setup with potential, but at this point, there are any number of $100-$250 GPS watches that are far more accurate for actual workouts. Here's one example of a GPS track, with the Fenix 3 in pink, and the other devices (iphone and 310xt). I have so many examples where I have the other devices tracking like this and the Fenix 3 showing crazy tracks. In this instance, the Fenix measured 12.5 miles, the other devices 14.6 miles.

Rated 5 out of 5 by from The Best Watch IM I always love logging miles and elevation gain in my adventures, I have owned a Edge 305 since their release to market. I liked it and use it all the time but this is everything that was x 10. The display gets brighter in the sun and in light which is when I need to see it the most. Controlling the music player on your smart phone is such a useful feature when doing activities, as is Caller ID and reading Text Messages; Now you will never need to interrupt your ride just dig your phone out of your camel back to see a telemarketer is calling however you can see when an important call is coming through. There is as much information as a person can handle available in very custom ways.The battery is amazing considering the other offerings in either the smart-watch or fitness-watch competitors from the likes of Apple or Sunto. The ability to update apps widgets, watch faces and operating system gives me peace that this will be up to date as long as I am. It serves my needs in every sport I do. Also this watch looks really really Good. This watch does every thing you could want I wouldn't trade it for a Rolex, seriously.

Rated 5 out of 5 by from Best Garmin to date! So far, I have used this watch for a dozen runs and a couple of bike rides. I feel strongly that this is the best watch Garmin has ever made! I haven't had any problems with loss of data like I did with the Fenix 2 (despite uploading the updates) and the features of this watch far exceeded my expectations. The HRM is similar to the Fenix 2 and is accurate, comfortable and stays put. My biggest complaint about the 920 was that I couldn't use it as a daily watch and a GPS tracker… finally, I found a watch that works great for both. I love that they decided to add the sleep and step tracking function added to this watch. It also has lots of cool extra features like weather apps, temperature screen, calendar notification and daily activity tracker, which I use often. It also pairs well with my iPhone and syncs my completed runs extremely fast (unlike the Fenix 2) to Connect. You can also use the HRM and the live tracking feature simultaneously, which is an upgrade from the 2. Bottom line, although expensive, this watch is everything I had hoped it would be. I am also excited to see what extra features can be added (different watch faces, apps, ect.) as Connect IQ develops.

Can the HRM be worn in the water?

Asked by: Soccerdawg
The HRM chest strap can be worn in water but it will not read your heart rate underwater. Currently there is no ANT+ or Bluetooth Smart strap is capable of transmitting through water on the market.

Is the HRM monitor save the data from the swim and download it to the watch after? If it is, what is the deferance between the HRM RUN and the HRM TRI ?

Asked by: G W
The included HRM-Run heart rate monitor will not measure heart rate data when swimming. You would need to purchase the HRM-Swim or HRM-Tri which both have the ability to send heart rate data to the Fenix 3 after your swim.
