I'm a fairly lean guy...I'm 6'2" 152lb. My wrists are skinny and bony but in proportion to the rest of my body... they are 6.75" in circumference. Sometimes, my watch does not pick up my correct heart rate. Sometimes it reads exactly half of what it should and in other cases it is between half and the actual HR like it is trying to catch up. I try to get it to read accurately by pressing it down on my wrist but I can't do that for an extended period due to the fact that I'm working out. Sometimes pressing it down will help but not always. As this is the core of what I need the watch for, I'm considering getting rid of it and just going to a chest strap which always reads correctly.
Anyone else have this issue and have any solutions? Thanks in advance!
