Garmin Astro GPS Dog Collar

Astro system consists of two components: a Handheld GPS unit -- Garmin Astro 220 which looks like a walkie-talkie and a Dog GPS Collar Unit Garmin Astro DC-40 with a whip style antenna that transmits your dog's location via radio signal. The Dog GPS computes its location from the GPS satellites and detects whether your dog is moving, on point, or treed.

The Dog GPS sends that info to your Handheld GPS every 5 seconds. The Handheld GPS plots the exact location of your dog on a map, shows distance, and whether your dog is moving, on point or treed. On your Handheld GPS, the MAP SCREEN shows your location, your dog's location, and the path that your dog has hunted.
