This package contains the handheld Astro unit only (no DC 20 collar) so that additional users may track the same dog. The Astro 220 also functions as a full-featured GPS receiver like the GPSMAP 60CSx, and lets you add MapSource detail for roads and trails.

Leave the hunting to your dog.
Tired of searching for your hunting dog in tall grass or dense cover? Now you can leave the hunting entirely to him. 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.
Attach Collar and Go
The Astro system includes a bright color-screen handheld GPS device and requires a wireless transmitter, called the DC 20. To get started, just take Astro outdoors and turn on the handheld and transmitter to acquire GPS satellite signals. Then attach the DC 20 to your dog, either with the neoprene harness or by threading it onto an existing 1-inch e-collar. Now you're ready to turn him loose - no other setup required.
Track Dogs in Dense Cover
As often as every five seconds, your dog's DC 20 transmits his position to your handheld, and you can see his current location and a trail of where he's been on the Map page of your handheld. Switch over to the Dog Tracker page to view a compass pointing to your dog's location as well as his current status: whether he's running, sitting, on point or treeing quarry. Astro can also sound an alarm to let you know instantly when your dog goes on point.
Astro boasts a high-sensitivity GPS receiver that can track your dog's position even in the densest cover. You can track up to ten dogs at one time with Astro, at a distance of up to five miles away (depending on terrain). The system transmits information by line-of-sight, so it reaches farthest in flat, open territory.
Count Your Coveys
After you've captured your quarry, mark the exact spot with Astro's Covey Counter, 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 you flushed and took from that location. Astro lets you save other special waypoints, such as "Truck" and "Lodge," so you can save the location of these places quickly and easily for each hunt. Astro also offers special waypoint icons to represent food plots, tree stands and other hunting-related points.
Experience Full-featured GPS
Astro shines when you're out on the hunt, but it also excels in getting you back to your truck at the end of the day, or even back home again. In fact, the Astro handheld has all the features of Garmin's top-line handheld outdoor devices, including a barometric altimeter, microSD card slot, celestial information, area calculator, rugged, IPX7 waterproof exterior and a revolutionary 3-axis compass, which works no matter how the handheld is oriented. With optional detailed city street maps (see the Accessories tab), you can search for over 6 million points of interest and create a route on roads with exact turn-by-turn directions.
