Heart Monitors

I received a test HR belt monitor from Bob Walz at the time he was
developing it. The watch face slipped into a metal sleeve attached to
the belt. This arrangement worked PERFECTLY until the day I lost it
(about one year later). I should have known this was going to happen,
because over time it was working loose and began to fall out at vet
checks, etc. A little duct tape mighta saved the day.

Anyway, I ordered a replacement Polar (wrist)watch from EasyCare and
it simply hasn't performed. Rodger has been very supportive, offering
ideas on how to make it work -- apparently the watch has to be within
three feet of the transmitter. I don't know what's different -- the
watch, the angle, etc. -- but I am simply not getting regular or
reliable readings. Perhaps I need to go back to the watch-on-the-belt
arrangement. Any ideas will be appreciated.

Riding with heartbelts has many times been proven problemsome. The placment
of the electrodes must be adequately disatnced from one another and placed
in
such a manner that body movement does not cause erratic readings. Hence, I
do not recommend riding with a heartbelt. They are very good and accurate
while stading or under ideal conditions, but in the the long run, you will
find the wired models such as the V-max are accuarte 95% of the time...AND,
they can be used with a separate heartbelt when the saddle is stripped for
continuation of reading at vet checks.

>>Teddy, I have heard this also, but wonder why it is? If they work
adequately for a human runner, why not for a horse? Why do the
electrodes have to be farther apart? Can you or Rodger comment on
this? Why would they be accurate for the horse standing, and not
the horse moving?

Karen: I e-mailed Roger today and asked him to respond to this. After all,
he developed this HRM and knows beter than I. He actually TESTS out every
type of monitor on his own horses in comeptition.
