Garmin Hrm-pro vs Garmin Hrm Tri

And then the actual, uh, stretchy part of the strap is very supple. Very stretchy. uh, very easy to use. And then there's the end clip, which is the i...

I bought this chest strap heart rate monitor to replace an older Garmin version. Paired it to a number of Garmin devices including a Fenix 5 and 6 watch and Edge 500 and 1000 Cyclometers. No issues with pairing, connecting during an activity and the additional functionality to collect data when swimming and the additional running metrics make the strap a joy for those into tracking their workout data.

Washed it recently, let it dry then no more pairing. Opened it up and noticed condensation in the battery compartment so decided that it was terminal enough to do "major" surgery to investigate.

Maybe if I washed this without the battery in (cover on) and then let it dry out I could have got a few more months out of it? This seems to be a pretty common problem with these series of garmin hrm units (pro, tri, run, etc) so buyer beware
