Item Description:
Introducing Astro, the first high sensitivity GPS-enabled dog tracking system for hunters and sportsmen. This unique system pinpoints your dog?s position and shows you exactly where he is, even when you can?t see or hear him.

For your outdoor adventures when your dog is not by your side whether it be hiking, camping or bike riding, the Astro 220 serves as a full-featured handheld GPS unit. It contains top-notch features such as a high-sensitivity GPS receiver, long battery life, a bright sunlight readable color display and a rugged IPX7 waterproof exterior. This unit also offers automatic routing with turn-by-turn directions. The Astro 220 has a micro SD card slot so you can add preprogrammed data cards with detailed maps such as TOPO, Inland Lakes, BlueChart and City Navigator.

Astro can track up to ten dogs at once and has the ability to update the dog's position every five seconds. In flat, unobstructed terrain, the Astro system can reach up to five miles. This system requires very little configuration out of the box. Once the transmitter and receiver acquire a GPS signal, the receiver will automatically display the location of the dog.

Note: Dog tracking with Astro 220 receiver requires the use of the Garmin DC20 transmitter(s).
