The Astro 320 handheld takes dog tracking to a higher level. It allows you to keep track of up to 10 dogs with multiple handsets and T 5 dog devices (sold separately). High-sensitivity Garmin GPS/GLONASS transmitter, enhanced map drawing capabilities, BirdsEye Satellite Imagery compatibility and a 3-axis electronic compass ensures you get to your truck or camp at the end of the hunt. And it’s all easy to get to through a vibrant, sunlight-readable 2.6-inch color display.

The Astro handheld and T 5 dog device boast high-sensitivity GPS receiver/transmitters. The T 5 has a top-mounted GPS antenna and is designed to keep its flexible, braided stainless steel radio antenna upright for best reception so you can track your dog’s position even in heavy tree cover or deep canyons. And it’s tough enough to run wherever you dog runs (water-rated to 10 meters).

You can track up to 10 dogs at one time with Astro, at a range of up to 9 mi away, depending on terrain.

You can track up to 10 dogs at one time with Astro, at a range 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.

As often as every 5 seconds, the T 5 dog device transmits your dog’s position to your Astro 320 handheld. Through the vibrant display, you can see your dog's current location and a trail of where he’s been on the map page. Switch over to the Dog Tracker page to view a compass pointing to your dog’s location.

When tracking multiple dogs with T 5 dog devices, you can also see each dog’s precise distance on the map page, and you can choose to auto zoom the map so all dogs can be seen on the display at any time. 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. You can also choose the duration that each dog’s track log is viewed on the display, or toggle it off completely.

Rescue mode provides a reduced update rate when battery life drops below 25 percent in order to preserve battery life and give you more time to look for a lost dog. The improved battery life means when you set your update rate to every 5 seconds, the battery lasts 26 hours. In rescue mode, the battery lasts 54 hours. 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 an Astro is used only as a search tool when a dog in competition becomes lost.

Getting what you need for the hunt is now a little easier. You can purchase the entire Astro bundle and as many T 5 dog devices with collars as you need. And your Astro 320 is compatible with every T 5 dog device.

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

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

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.

Take charge of your next adventure with BaseCamp™, software that lets you view and organize maps, waypoints, routes, and tracks. This free trip-planning software even allows you to create Garmin Adventures that you can share with friends, family or fellow explorers. BaseCamp displays topographic map data in 2-D or 3-D on your computer screen, including contour lines and elevation profiles. It also can transfer an unlimited amount of satellite images to your device when paired with a BirdsEye Satellite Imagery subscription.

Load your laptop with BaseStation software to turn it into a field control center for tracking multiple dogs (T 5 dog devices). View real-time GPS information on the larger display of your computer, making it ideal for canine search and rescue teams. And because it’s GPS/GLONASS, you'll get safe, secure and more effective tracking, even where Internet and cell phone service isn’t available.

¹The DC 50 is compatible with the Astro 320 handheld only (software upgrade required). It does not work with Astro 220 or Alpha™ handhelds.
