I am having the same problem with the HR transmit cutting in & out during my workout. It also randomly displays HRs in the 40-70s range in the middle of a run (and am just not in THAT kind of shape). Could this also be a weak battery (it's done this since I purchased the watch)? or is it just kinda part of being a lady- with the
strap under my sports bra- is it picking up "bounce" instead?
I am curious what the story is before I invest in batteries. No one seems to sell them around here, so I'll have to pay shipping. And would this be the transmitter battery only, or both?
Thanks!
