The Tracker4 is one of the fastest and easiest-to-use beacons in the industry featuring a rubberized over-molded case, large LED display, and the same BCA Tracker interface that basically makes it impossible not to find your companion. This version also includes Signal Suppression and Big Picture modes for no-nonsense multiple-victim searching, as well as motion-sensing auto revert-to-transmit mode. The software and electronics performance testing are also upgradeable fleet management.
