    • It works really well for running and Bike, for Swim I had some issues syncing.

It works really well for running and Bike, for Swim I had some issues syncing, but that may be my issue, other people I train with use it and have no issues.

    • good device; stores HR data when out of range of watch (swimming, climbing, soccer, etc)
Style: Monitor
I run 40-50 miles a week plus cycle when weather permits and I use Garmin to track my time, distance, speed, HR, HRV, etc. stats. I feed the Garmin data files into FirstBeat Athlete and use its coaching feature to know when to rest, go light, and go hard. But I also play sports where wearing a big watch isn't desirable or permitted and this meant I couldn't collect data for these workouts. I was left trying to estimate key stats and manually putting them in to Garmin Connect and Athlete. Otherwise, it would assume I had taken that day off when in fact I had done monster workout(s). So when this HRM came out I was excited because one of its capabilities (primarily for swimming, where water will block the ANT+ signal) is to record HR data when a watch/etc is out of range and then later dump it all to the watch. I am happy to report it works as advertised with my Garmin Fenix3 watch. One important thing to note is that you MUST START THE ACTIVITY ON YOUR WATCH WITH THE HRM CONNECTED (IN RANGE). When you get done, you stop the activity on your watch and it will give you the option to look for and download stored data. Sometimes I have to try a second time but I've never lost a stored workout (not true any more -- see edits below). Make sure you download the stored data while still wearing the strap. If you take it off, you will get spurious HR readings if your watch doesn't have optical (wrist) HRM and, worse, the strap will eventually turn off/time out, taking your stored data with it. This HRM accurately records the R-R data that FirstBeat requires. I've found this HRM-Tri to be more comfortable than the Garmin HRM-Run I was using before. The elastic strap part feels more robust and that, plus the silicon-like rings on the contact patches, mean this stays in place more than the HRM-Run. It's less annoying overall on long, sweaty workouts than the HRM-Run. It also has only two contact patches instead of the three or four, depending on which HRM-Run version you have. One downside to the HRM-Tri over the HRM-Run is that the electronic sensor part does not pop off like it does on the HRM-Run. As a result, you have to hand wash the Tri once every seven uses while the Run you can toss the strap in the wash on gentle. The HRM-Tri uses lithium CR2032 coin-style batteries. When the strap is working right (see updates below), they last a very reasonable amount of time and the watch will alert you with a low battery warning with enough juice left for several more workouts (ie, you need to replace the battery soon but not right before THAT particular workout). There are four very small phillips screws holding the battery cover on. Normal screwdrivers are way too big -- you'll need eye-glasses type ones. I do not swim so I can't comment on that use. These are great for competitive sports or where you can't safely wear a watch. For example, I use this regularly for soccer games and for climbing. 2016/01/14 edit -- I've noticed in FirstBeat Athlete that for the same runs, the HRM-Tri tends to have a noticeably higher error % than the HRM-Run. For example, on a 30-min treadmill run the Tri error rate is typically around 12-18% while the Run is 2-6%. There is no immediate obvious downside to this outcome so for now I am not docking a star on the Tri. 2016/03/25 edit -- I'm bumping down to 4 stars for two reasons. First, as mentioned in my edit above, the Tri gets a higher error rate during "connected" activities where the watch is in range the whole time. I've come to realize that FB Athlete seems to not count error periods or count them as less. The net effect is that given the same stats (same time, distance, avg HR on a treadmill) runs with the Tri seem to be rated slightly less intense which I believe is due to its higher error rate. So for normal running, I tend to stick with the HRM-Run. Second, the HRM-Tri gives very high error rates in FB Athlete (40-55%) when I use it in disconnected mode during competitive sports. 2017/11/29 edit -- About 1.5 years ago, I upgraded from the Fenix 3 to the Fenix 5s watch (the 5s is superior in every way). The Tri worked just the same with the 5s. Since the 5s has the built-in optical wrist HRM, it can be hard to make sure the Tri has connected and is being used instead of the less accurate (and without HRV/R-R data) optical sensor. Unfortunately, almost exactly two years after I purchased the Tri, it has to be replaced. It's chewing through the CR2032 battery every couple days with perhaps 6-10 hours of use. I tried a fresh new set of spare batteries to make sure my original spares hadn't gone bad. I followed the instructions for care and it's definitely been showing signs of wear and tear. Overall I'm still happy and will be replacing it with another one. 2019/11/30 edit -- These HRM-Tri are now lasting six months. I'm on my FIFTH one since the 11/29/2017 review. Every time, they fail by chewing through the CR2032 batteries like candy. When they are failing, they often use the battery so fast that I won't get a low battery warning (like normal) and it will simply die in the middle of an activity, losing all my data. Dropping another star here to three and may drop to two, depending on how my contact with Garmin goes. I am now using the Tri with a Garmin Fenix 6S Pro watch and, when it's working properly, it works well. ... show more

    • Vital for better accuracy
Style: Monitor
Yes, this is a must if you are interested in tracking your HR during workout. My watch does work well but with the heart rate monitor, it captures info more accurately in my opinion. I've used this for almost 2 years now and only just now changed the battery. The battery is easy to manage. I let my hubby change it for me. He found it easy to do after researching instructions online. Now its going strong again. The device can be easily misplaced so i always keep it in my gym bag to keep up with it. I've had it come apart only a few times, at the clip area, when working out but thats rare. I would also like to clean it more. When I use it vs dont, you can truly see a difference in my workout stats. I would highly recommend this device for novice to experts. ... show more

    • Good investment if you plan on swimming with your garmin
I purchased this bundle and have primarily been using the HRM Swim. I use this with a fenix 3 and it was a snap to setup and instantly connects when out of the pool. The only drawback is while swimming there is no heart rate feedback. I knew this before purchasing and I believe it is a limitation of the transmission type used and not a design flaw. The HRM swim stores your information and when you step out of the pool syncs to the watch. It does provide a nice overview of swolf, hr, speed etc. in the app. The swim strap seems to be holding up great to the harsh chlorine of the pool and looks brand new after being used about 3 times a week 1-1.5hrs at a time for a couple of months. Just as an FYI the HRM-Tri will also store the info just like the swim but the design is very different. It is designed for a triathlon making it a jack of all trades (swim, run, bike), but a master of none and won't hold up to the chlorine in the pool for very long. It also doesn't fit nearly as snug since it has more elastic in the band (the swim has very little give so once you get it around your chest it is going to stay put). I use the Tri mostly if I forget the HRM- Run going to the gym. The Run is the most comfortable and flexible strap for just working out, or going for a run. I have used the Tri a few times biking, running and lake swimming and it worked fine. You might be thinking do I really need all three? No, you could get by with the Run and Swim. The other question I had was if the Run is water proof why can't I just use that for the pool? The HRM-Run is water proof but doesn't store data like the Swim or Tri so it's useless to swim with since the watch and HRM cannot connect while in water. It also would fall apart rather quickly from the chlorine and the band is too elastic and would lose contact at each turn of a lap. If I were to do it again I would probably only get the HRM-Swim and the HRM-Run because they are much better for their particular activities and since I am just training I don't mind switching HRMs. I would then get the Tri when it got close to race time, unless you can get a deal on the bundle. Apologies for the long review and congrats managing to get this far. I wanted to share some of my learnings about the different HRM bands since the info can be hard to find along with my experience of using them. ... show more
