I got my adapter kit from Roger Rittennhouse. I don't know if it is
the same kit as the V-MAX. I got mine from Roger at the AERC
convention two years ago and it works great. Better than any other heart
monitor I have owned. You use the transmitter from your Garmin with
this kit. Rogers email is in the 2009 membership guide and he is in the
southeast division. His email in the guide is roger@xxxxxxxxxxx. This may be the
same as distance depot and if it is I would highly recommend
it.
