Frustrated with my Polar HRM

JBennis1013

So my Polar HRM is starting to annoy me. I clean the strap regularly and every time I exercise it takes some time for it to pick up my heart rate. During my work out it will go back to 00 and then jump back up. It does this quite often during my work out. Does anyone have this issue and if so what do you suggest to help with the issue?

Thanks
