HRM connection issues

Posting this here cos I thought it would be something people here would have experience with.

I've got a wahoo tickr and I'm having major consistency issues with it, keeps sticking on a number or dropping out entirely.

My first strap broke (connector stud snapped), tried it on an old garmin strap with no consistent connection, nor on a cheap amazon strap, so I got another Wahoo one. Which had been working OK-ish till the last week or so.

I've traced it to a connection problem because if I wet two fingers and press them against the studs on the unit itself the LEDs light up as they should.

Anyone got any tips to keep the connection working? I've been following the wahoo recommendations for cleaning the connectors etc but it's not helping much. And made sure new battery etc. etc..

I'm loathe to buy another because I have only had this for 14 months and I've had 2 Garmin ones previously that died completely.

    Mine recently started doing the same - constant values, unrealistically low values, occasional dropout. I changed the battery which helped but didn’t fix it. I did a reset (insert the battery upside down for a few seconds) which seemed to fix it, and I also bought a generic strap off of Amazon which it worked perfectly with last night. Make sure your Wahoo strap is tight enough - this will help maintain a connection.

    Tried the hard reset, seemed to be mostly OK yesterday after the first couple of minutes. Much easier to control on the turbo though because you can just keep resetting phone/hrm until it works, on the road you can't really do that.

    Ok that didn't work, it's still rubbish.

    I also tried changing the battery again and using all my other straps.

    I've come to the conclusion that it is f*cked again and HRMs need to be treated as essentially disposable items with a 12-24 month life.

    Has anyone tried using the Tri versions? They don't look too much more expensive and could be a bit more robust (since you can swim in them).
  • Wish I had looked into things better in Feb '17, spent ~£40 on a Polar H7 hrm which was Bluetooth only and often lost connection to my mobile or GPS unit, then bought a Coospo H6 (which also does ANT+) for ~£25 in Jan '18 and it's been great bar the odd ride when the cr2032 battery was running low.
