The DC 20 is a wireless transmitter that transmits a signal to your Garmin Astro 220 handheld GPS Dog Tracking Device (not included). Simple and easy to use, you just take the Astro outdoors and turn on both units to acquire a GPS satellite signal, then attach the DC 20 to your dog, either via the included neoprene harness or by threading it onto an existing 1-inch e-collar, and you're ready to go.

The DC 20 transmits your dog's position to the 220 every five seconds, showing current location as well as where he's been on the Map page. The Dog Tracker page shows you a compass that points to your dog's location, and lets you see your dog's current status, such as running, sitting, on point or treeing quarry. The Garmin Astro can even sound an alarm to let you know instantly when your dog goes on point.

The Astro 220's high-sensitivity GPS receiver can track your dog's DC 20 transmitter signal up to five miles away in open territory. The Astro features a Covey Counter, which lets you place a special waypoint that tells you the exact location, time of day and elevation where you found your prey, as well as the number of birds flushed and taken from that location. The Astro also lets you save other important waypoints, such as Truck and Lodge, and choose special icons to represent food plots, tree stands and other hunting-related items.

The Garmin Astro DC 20 is a single dog-tracking transmitter, and requires the Astro 220 in order to be used. This unit has an extremely rugged construction, with an IPX7 waterproof exterior that can withstand full immersion in water up to 1-meter deep for up to 30 minutes, and can be used without interference with up to nine other DC 20 transmitters via a single Astro 220 handheld tracker.
