  • It works by receiving signals from additional Alpha 100 handhelds, TT 15 and TT 15 mini dog devices (each sold separately).

  • It can receive notifications when your dog is ‘Treed’ or ‘On Point’
  • It updates your dog’s location as often as every 2.5 seconds
  • You can use the handheld and tap the screen with gloves
  • When using a vehicle to find or follow your dogs, the Garmin DriveTrack™ 70 dog tracker and GPS navigator (sold separately) provides an easy-to-watch “big picture” solution. 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.
  • BirdsEye Satellite Imagery (subscription required) is an add on that allows you to have a better-than-real-life view of terrain, including roads, water, woods and more.

It also can transfer an unlimited amount of satellite images to your device when paired with a BirdsEye Satellite Imagery subscription.
  • You also have the option to use your computer as a tracking station. You can load your laptop with BaseStation software to turn it into a field control center for tracking multiple dogs and/or buddies (up to 20 Alpha units, TT 15 or T 5 dog devices). View real-time GPS information on the larger display of your computer, making it ideal for canine search and rescue teams. And because it’s GPS and GLONASS, you’ll get safe, secure and more effective tracking, even where Internet and cell phone service isn’t available.
