The Astro system includes the redesigned Astro 320 and the rugged, orange polyurethane DC 40 transmitter collar. The collar accommodates most e-collar receivers, eliminating the need to put two separate collars on a dog. Plus, Collar Lock creates a 4-digit PIN number that helps prevent others from seeing your dog’s whereabouts — a useful feature in field trials to ensure that an Astro is used only as a recovery tool when a dog in competition becomes lost.

 See Your Dogs' Every Move

More intuitive and easier to use, the new Astro 320 takes dog tracking to an entirely new level. The interface streamlines what is displayed by allowing dogs that are outside the current zoom level to have their location notated in the display’s margin. The user also can choose the amount of each dog’s tracklog displayed, or toggle it off completely, to avoid cluttering the map

The Astro 320, compatible with any Garmin DC series transmitter, also debuts innovative features like enhanced map drawing capabilities, BirdsEye Satellite Imagery compatibility (subscription required), vibration-based alerts and a 3-axis electronic compass.

Thanks to the redesigned antenna, the maximum range between the Astro 320 and a Garmin tracking collar has been increased by nearly 30 percent – up to 9 mi in flat, unobstructed terrain.

Both durable and waterproof, Astro 320 features the legendary toughness that’s built to withstand the elements – be it dust, dirt, humidity or water, none of which are a match for this essential hunting companion.

Upgrade with Ease

Getting what you need for the hunt is now a little easier. Hunters have the option of purchasing the entire Astro bundle, a stand-alone Astro 320 or as many DC 40 collars as necessary. And if you do get the 320, remember it’s compatible with every DC series dog collar.

Get Additional Mapping

With its microSD™ card slot, Astro 320 lets you purchase and load TOPO U.S. 24K maps for land elevation contours or City Navigator NT map data for turn-by-turn routing on roads (see maps tab for compatible maps). Astro 320 also supports BirdsEye Satellite Imagery (subscription required), that lets you download satellite images to your device and integrate them with your maps. Mapping depicts important nearby geographical features – and lets hunters know, for example, if their dog has crossed a creek or is nearing a dangerous road.

In addition, Astro 320 is compatible with Garmin Custom Maps, free software that transforms paper and electronic maps into downloadable maps for your device.

Track Dogs in Dense Cover

As often as every 5 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 also can sound an alarm to let you know instantly when your dog goes on point.

Each dog’s precise distance also can be presented on the map page, and users can choose an option that auto zooms the map so all dogs can be seen on the display at any time. Alternately, dogs that are too far away to fit on the map’s current zoom scale can be notated on the display’s margin in the direction of the dog’s location. The user also can choose the duration that each dog’s tracklog is viewed on the display – or toggle it off completely for a cleaner display.

Astro boasts a high-sensitivity GPS receiver that can track your dog’s position even in the densest cover. You can track up to 10 dogs at one time with Astro, at a distance of up to 9 mi 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 Counte , 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
