HRM-MOD-TIMEX-& GARMIN 301/305 Trans Mod
Pictures of the TIMEX GPS+HR modified for use with a saddled horse. Lead wires are attached to the transmitter strip contacts. Lead electrodes are placed under the saddle and girth. For full design details and the test reports go to www.vmaxept.com. I also use this kit for use with ANY standard human HRM strip style transmitter, we are using this setup on all the monitors we ride with.
This mod also applies to the GARMIN 301/305 HRM Transmitter

The final electode method as of 11/13/03. I think the use of the small dot snap on electrodes along with the waterproof tape of the exposed contact of the trans offers the best method
