T61 Coded Transmitter and Belt Set - If you exercise in a crowded health club, chances are that you're hanging out with other athletes who monitor their workouts with a heart monitor. Stand too close to one of them and your heart rate monitor might pick up their signal--a growing phenomena known as crosstalk. If you own a Polar SmartEdge™ and Achiever series model (except the Protrainer NV™), you can tune out other signals with this T61 Coded Transmitter and Belt set. Like all Polar Transmitters, it features a one-piece sealed design that's 100% waterproof and the transmitter signal should last up to six or more years--even if you're exercising every day.

* 100% waterproof
* eliminates crosstalk
* Available for the Polar SmartEdge™ and Achiever series model (except the Protrainer NV™)
* Two-year maintenance-free warranty
