In our trailer we use Mighty Lite mats for cushioning & dust free Kitty
Litter to soak up urine. We try to let the horses out every 3-4 hours while
hauling & they usually go then.
I bought a "People" HRM, don't remember the brand. The snaps on the transmitter
were compatible with the snaps on the electode & wires Roger sells. The
transmitter & watches are interchangable too. If you're buying from a bike shop
order some wires & electrodes for the horse & take them to the shop & see if
they snap on the "people" transmitter. But some of the watches are NOT
waterproof(Mine Wasn't) & don't work in the rain. Roger, do you have a chest
belt people can buy to use your horse monitor on themselves???
