I have never been able to get my heart rate monitor to work consistently. I have a Garmin Edge 500, previously had a 305 (more than one) and since I started riding five years ago, I have always had issues whenever I tried using the HR monitor. So, for the most part I haven't bothered.

I am a full 34D and I'm wondering if this is part of my problem. Maybe I can't get it to go as high as it's supposed to go? I put it just under my "girls" , as high as I can get it, sometimes with the elastic of the bra over it. I have warn it on the tightest setting, which feels too loose and it would only sometimes engage and tell me my HR. DH uses the goopey stuff doctors use to do an ultra sound on his. He read somewhere that it helps get a better reading and it seems to work for him. So I tried that and it didn't work. Someone told me his wife makes hers tighter with safety pins. I tried that today, with the goopey stuff and still it only sometimes registers my HR. If I push against the monitor, I can usually get it to tell me my HR. I could try making it even tighter, but I'm not feeling very hopeful that will work.

Should I try putting it above my boobs? That doesn't sound very comfortable, but I don't think I have tried it. DH has changed the battery, and we have tried more than one strap as Garmin computers got lost, crushed, upgraded, etc.

Any tips you guys might have would be great.
