Garmin Astro 900 T9 GPS Collar

With faster 2.5-second location updates and the capacity to follow up to 20 dogs, the Garmin Astro 900 is a handheld powerhouse of a dog-tracking performance. Using this T9 collar device to transmit each dog’s location as often as every 2.5 seconds, Astro 900 Handheld (sold separately) is quick to pinpoint the track they’re following, even when they’re on the run. On the handheld device’s bright, crisp display, you can see your dog’s current location and a trail of where he’s been. You also can switch over to the Dog Track page to view a compass pointing to your dog’s location.

Reduces Clutter and Share Track Code

To reduce visual clutter on the map, you can toggle between show all, show some and show none by selecting the duration that each dog’s track is viewable on the handheld's display. You can also share a dog’s track code so another person can view your dog’s location on their unit’s map, along with the dog tracking compass. Further, by sharing a dog’s control code, you can allow another person to configure and control your dog’s on-collar device.

Track with Hunt Metrics Dog Data

Sophisticated Hunt Metrics data helps monitor your dog’s hunting patterns and behaviors to optimize your training opportunities. You can see your dog's times, distances traveled, and overall scores. Plus, Astro 900 will also capture the number of times during the hunt when an on-point or treed event was indicated.

Count Your Coveys

After you’ve tracked down your quarry, mark the exact spot with the Astro device’s Covey Counter, a special waypoint that shows 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.

Share Wirelessly

With an expanded ecosystem of wireless connectivity options, Astro 900 can support unit-to-unit data transfer with a variety of compatible Garmin devices.

Turn Your Computer Into a BaseStation for Tracking Dogs

Load your laptop with BaseStation software to turn it into a field control center for tracking multiple dogs (equipped with T9). 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 and GLONASS capable, you'll get tracking, even where internet and cell phone service isn’t available.

Tough, Water-resistant, Long-Lasting

Like all Garmin outdoor products, Astro 900 is designed to be effective, easy to use, reliable, and rugged enough to withstand all the blows, bumps, and sloppy conditions of training and hunting.

Note: This collar device needs to be paired with a handheld device (not included) for operation.
