Designed to be “pocket friendly,” T3 is the choice of guides, mountaineers, and the weight-conscious crowd. Signal Suppression (SS) and Big Picture (BP) modes for no-nonsense multiple-victim searching. Motion-sensing auto revert-to-transmit mode. Upgradeable software and electronics performance testing for Tracker3 fleet management. All transceivers include harness and batteries.
