Garmin HRM Tri Heart Rate Transmitter and Strap
Made specifically for triathletes, this is Garmin's smallest and lightest heart rate monitor available. The strap is easily adjustable and comfortable both in and out of water. When in water the transmitter stores heart rate information and forwards it to the 920XT, Fenix 3, and Epix when out of water.
Heart Rate Data in Three Disciplines
This 2.4 GHz ANT Wireless Heart Rate Transmitter and Strap is designed for Triathletes in mind. It is smaller than most other transmitters and comes with a comfortable adjustable strap. Its soft, rounded edges and covered seams make the strap super-comfortable out of the water, too.
