The Garmin Alpha 100 Dog Tracker System helps you track, train and control your sporting dogs. To help your dogs reach achieve optimum performance, the Garmin Alpha Dog GPS system combines proven Garmin GPS dog tracking technology with Tri-Tronics electronic dog training. This easy-to-use integrated handheld system allows you to track and train your dogs in the field from a range of up to 9 mi, delivering their exact position as often as every 2.5 seconds. With the Garmin Alpha 100 and TT 10 (available as an option), you can pinpoint up to 20 dogs or hunters' exact positions on a large, glove-friendly touchscreen display even when they are out of sight. Since the Garmin Alpha 100 Dog Tracker comes preloaded with 100K U.S. TOPO maps you'll always know your surroundings.

The Garmin Alpha 100 is designed to help you track your dogs. You can measure each dog's speed, distance and the direction being traveled. Plus, you can receive notifications when a dog is "Treed" or "On Point." A single Alpha 100 can track up to 20 dogs or fellow hunters when using either additional Alpha 100 handhelds or TT 10 devices (each sold separately, not compatible with Astro). Upgrade your view with a BirdsEye TOPO maps subscription for a better-than-real-life view of terrain, including roads, water, woods and more.

The Garmin Alpha 100 GPS helps you train and control your dogs, to stop chasing unwanted game or "recall" them to your position. Easy to access training buttons allow you to communicate separately to each dog through safe and effective features, including 18 levels of momentary and 18 levels of continuous stimulation or an audible tone command. Plus, a lockout setting is available to avoid accidental stimulation or tone. Two modes of level progression let you customize your training even further. Traditional stimulation allows you to make quick changes within a predetermined stimulation level (low, medium or high). Whereas linear stimulation allows progressively more stimulation through all 18 levels available.
