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. 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.
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.
I do not swim so I can't comment on that use.
Overall I'm extremely pleased with this item.
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.
It works as advertised! I've run with it a few times now, including an 11+ mile run. I hardly know it's there. No irritation at all. Of equal importance, my HR, cadence, vertical oscillation, and ground contact time are all consistent with the data I was getting from the HRM-Run. It's not only comfortable, but trustworthy.
I will never swim with it, but I look forward to many long, comfortable runs and bike rides. Thanks, Garmin!
The HRM worked well on the first run. Saliva wasn't enough for a good contact but water from the water bottle worked well. Paired with my 920XT easily.
Trying it out on a bike later in the day.
Looked at Garmin Connect and there was a ton of data not available before - HR, Cadence, Stride Length, Vertical Oscillation, and Ground contact time (including left and right balance). Cadence and HR passed over to TraingPeaks without an issue.
