I use cheap ones too...put it in your ears and tap
with a finger, you definately shoud hear that! Try for your own
heartbeat....if still nothing, sometimes the rubber tube is sort of
backwards...hard to explain, take the thing apart and look...
I bought a stethascope at the local pharmacy thinking the $7.95 one is as
good as the one for $19.99. Either I'm going deaf or I've been riding a ghost
horse! I can not find a heartbeat with that thing to save my soul. Is there
that much difference in stethascopes??? Should I just quite being cheap
and buy a moniter???
