Garmin Astro 320 GPS Tracking Collar w/ DC-40 (2 Dog Combo)

The Astro 320 improves user interface with a simpler menu structure and sophisticated graphics thanks to its vibrant, sunlight-readable 2.6" color display. Both durable and waterproof, Astro 320 is built to withstand the elements. It features the legendary toughness built for the rigors of the outdoors – be it dust, dirt, humidity or water, none of which are a match for this essential hunting companion.

The 320 features a built-in worldwide basemap with shaded relief, plus support for enhanced mapping such as BirdsEye™ satellite imagery, Topo maps, and Garmin custom maps. Hunters know, for example, if their dog has crossed a creek or is nearing a dangerous road. Garmin's free BaseCamp software allows hunters and trainers to download, view and save their dog's tracks to a computer for viewing later – a great tool for evaluating performance.

A refined user interface streamlines what is displayed on screen by allowing dogs that are outside the current zoom level to have their location notated in the display's margin. The user can also choose the amount of each dog's tracklog displayed, or toggle it off completely to avoid cluttering the map.

This rugged handheld also has a built-in vibration motor to support silent alerts in addition to audible tones, a 3-axis digital compass (allowing the hunter to hold the handheld at any angle), improved reception range, a fully rubberized outer coating with an over molding for a better grip, a new keyboard design, and onboard memory for storing additional mapping (1.7 Gigs). The new handheld also features a handy keypad lock so buttons aren't accidentally pushed while being carried in a pocket or through thick brush. The orange trim color is great for hunters and especially helpful for visibility if the handheld is dropped or misplaced.

Now offering two new included antenna options, the extended range antenna can increase the tracking range by up to 30%. Thanks to the redesigned antenna, the maximum range between the Astro 320 and a Garmin tracking collar can achieve up to nine miles in flat, unobstructed terrain. Dog handlers can wirelessly transfer waypoints, tracks, and even their dog's tracking settings to other Astro 320 users.
