Alpha® Bundle (Alpha 100 and TT™ 15 Dog Device)


An invaluable tool in the field, the Alpha 100 helps you achieve optimum performance from your sporting dogs. It combines proven Garmin GPS dog tracking with Tri-Tronics® electronic dog training technology. This easy-to-use integrated handheld system allows you to track and train your dogs in the field at a range of up to 9 miles (TT 15) or 4 miles (TT 15 mini) away, delivering their exact position as often as every 2.5 seconds.

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 even when they are out of sight. Because Alpha 100 comes preloaded with TOPO U.S. 100K maps, you’ll always know your surroundings.
