The familiar, easy-to-use Tracker is back in a 20 percent smaller, lighter package. Like its predecessor, the Tracker3 features three antennas as well as an instantaneous real-time display. Signal suppression eases multiple burial scenarios by hiding a found victim’s transmission in order to focus on the next closest burial and Big Picture Mode helps by displaying each signal’s distance and direction. A USB port in the battery compartment allows you to download software updates.
