The Backcountry Access Tracker 2 subtracts weight and size, and adds real-time display and a third receiving antenna to the best-selling, dead-simple Tracker DTS. The third digital antenna increases accuracy and provides a strong buried signal in any orientation, while the real-time display eliminates lag time, allowing you to narrow your search zone quickly when seconds count. The Tracker 2's single search / transmit switch makes learning and teaching a snap, and it reduces confusion when you hit adrenaline overdrive.
