Introducing the Next-Generation Garmin Astro 320 GPS dog tracker! Also see the Astro 320 Bundle (the bundle includes a DC-40 collar with the Astro 320 handheld unit).
Garmin Astro 320 delivers what hunters have asked for:
- Increased range
- Sophisticated built-in mapping capability; also supports additional mapping with Garmin Custom maps, BirdsEye ™ (overlay satellite imagery), and TOPO 24K
- Vibration mode for when you want silent alerts
- A simplified, streamlined user-interface.
You can upgrade right now! The new Garmin Astro 320 handheld GPS unit is compatible with your DC-20, DC-30 or DC-40 collars!
- Longer Range - nearly 30% greater
The Astro 320 handheld comes standard with a removable VHF antenna and a flexible, long-range antenna with a range of up to 9 miles with the DC-40 collar.
- Built-in Memory
Now there is 1.7GB of internal memory.
- Built-in Worldwide Basemap
Now features a built-in, shaded relief worldwide basemap that shows basic geographical features such as roads, streams, rivers and ponds.
- Vibration Mode
New vibration mode for when you want silent alerts.
- 65k full-color TFT MAP screen display
The 6.6 cm (2.6") screen display now shows more detail in full-color and can be read in sunlight.

- Easy-to-use options to customize maps
No more cluttered maps! Now you can customize the map to show as much detail or as little detail as you like. With the push of a button you can toggle between:
- Hide or show dog names
- Hide or show dog status
- Hide or show dog distance
- Hide or show off-screen dogs (in the margin)
- Hide or show complete history or partial history
- Much easier to set up multiple dogs
Set up your first dog and the Astro 320 will automatically use the same settings for the rest of your dogs. (You can, of course, make changes if you don’t want the same settings for all dogs.)

Wirelessly transfer waypoints, tracks, and even your dog’s tracking settings to other Astro 320 users
