Looking to purchase a new handheld transmitter or perhaps replace your existing Astro 220 handheld with the new, upgraded Garmin Astro 320?  The new Garmin Astro 320 Handheld has finally arrived for your Garmin Astro 320 unit!

The Astro 320 dog tracking system has evolved with a high-sensitivity GPS receiver that can track your dog’s stance and position even in the thickest of cover. Depending on the terrain you are hunting in, you can track up to ten dogs at one time at a distance of up to nine miles away.

Please note:  You must purchase DC-40 or DC-50 collar transmitters for EACH dog.

Count Your Coveys

Using the Astro’s Covey Counter™, a special waypoint 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. Mark 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

Don’t ever get lost in the woods again!  The Astro will lead 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, 3-axis 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.The Astro 320 improves user interface with a simpler menu structure and sophisticated graphics thanks to its vibrant, sunlight-readable 2.6” color display.

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.

With an optional BirdsEye Satellite Imagery subscription, hunters can pinpoint buildings, powerlines, and even individual trees – directly on their Astro 320.

Use the Garmin free BaseCamp software to download, view and save off your dog’s hunting patterns to a computer so you can go back to it at a later point – this is a great way to view your hunt and evaluate your dog training.

This sturdy, well-made, tough handheld also has a built-in vibration motor to support silent alerts, 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 safety keypad lock so buttons aren’t accidentally pushed during the hunt. It sports an orange trim color that is especially handy for hunters to spot the unit if it falls out of your pocket or bag during a hunt or is simply misplaced.

This unit has the ability to transfer waypoints, tracks, and even their dog’s tracking settings to other Garmin Astro 320 users wirelessly.

If you already have a Garmin collar, full backwards compatibility is offered with all existing Garmin dog collar products and most current accessories including the Garmin DC-20, DC-30, or DC-40.
