With multiple Alpha 100 handhelds and TT™ 15 or TT 15 mini dog devices, pinpoint up to 20 dogs or hunters’ exact positions on a large, glove-friendly touchscreen display. Comes preloaded with TOPO U.S. 100K maps. Measure each dog’s speed, distance and the direction being traveled. Receive notifications when a dog is “Treed” or “On Point.” The 7-inch moving map display shows dog positions overlaid on TOPO contours or satellite image views – along with navigation cues that help point you to your dog’s current location.
