Garmin DC 40 Transmitter Collar (For Astro)

This rugged, all-weather collar combines a high-sensitivity GPS receiver and VHF antenna into an all-in-one transmitter that works with the Astro® 220 or 320 to safeguard against your dog getting lost. Astro DC 40 sports a durable one-inch orange polyurethane collar that fits most e-collar receivers — eliminating the need to put two separate collars on a dog. Plus, Collar Lock uses a four-digit PIN number that helps prevent others from seeing your dog’s whereabouts.

Attach Collar and Go

When teamed up with the Astro™ 220 or 320, this system will have you hunting in no time. The DC 40, in combination with the Astro 220 or 320 pinpoints your dog’s position every 5 seconds. An innovative charging connection with a flashing LED-charging indicator lets you know when the battery is ready to go. You can extend the battery life of the DC 40 by changing the position transmit rate from 5 to 10, 30, or 120 seconds, enabling the DC 40 to work up to 17-48 hours in the field on one charge. You will know if your dog is pointing, sitting, moving or treeing. Where your dog is. Where it’s been. How fast it’s moving and how far it’s gone.

Track Dogs in Dense Cover
As often as every five seconds, your dog’s DC 40 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 seven 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, electronic compass, microSD™ card slot, celestial information, area calculator and rugged, IPX7 waterproof exterior. With optional detailed city street maps, you can search for over 6 million points of interest and create a route on roads with exact turn-by-turn directions.
