Garmin Dual Heart Rate Monitor

Just purchased the garmin dual with a bluetooth connection hoping it would resolve my issues. The hrm pairs via bluetooth and works for 10 mins then drops out or remains at a false heart rate then kicks back in and drops back out then back showing a true figure.
Anyone else having the same problem. All other bluetooth connections work fine with the elite drivo trainer that I use.

Kenny. Have a new dual garmin HR monitor about 3/4 weeks, no issues at all. Also connected to garmin 910XT / Watt bike at same time and data correct. Sorry no help. Darren

Hi Kenny

It might need a new battery. I had a new Dual, which started dropping out and then not connecting at all, after only 3 months. I hadn’t been using it more than 3-4 times a week until then. I took it into the local dealer assuming it was faulty and they just changed the battery, and it’s worked perfectly since then.

My Wahoo bluetooth HR strap eats batteries compared to my Garmin ant+ ones, always assumed it was something to do with the signal. So I would suggest trying a new battery.

Thanks Darren!

Thanks Dave, will change the battery.

Thanks Paul, will change the battery!

I don’t think the Wahoo ever switches off, mine eats batteries and even when I’ve taken it off I can see the lights flashing.

Thanks Neil!
