Track Dogs in Dense Cover
You can see his current location and a trail of where he’s been on the Map page of your handheld. Switch over to the Dog Tracker page to view a compass pointing to your dog’s location as well as his current status: whether he’s running, sitting, on point or treeing quarry. Astro can also sound an alarm to let you know instantly when your dog goes on point.
Astro boasts a high-sensitivity GPS receiver that can track your dog’s position even in the densest cover. You can track up to ten dogs at one time with Astro, at a distance of up to seven miles away (depending on terrain). The system transmits information by line-of-sight, so it reaches farthest in flat, open territory.
Count Your Coveys
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.
Experience Full-featured GPS
Astro shines when you’re out on the hunt, but it also excels in getting 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, 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.
Due to varying international regulations, this version of the Astro is approved for use only in the United States.
The sale and unlicensed use of the Garmin Astro GPS Dog Tracking System in any form is presently prohibited by the Canadian government. According to a document published by Industry Canada dated June 2009, the MURS radio frequency used by the Astro will be permitted to be sold and operated on a license-free basis at the end of a five-year transition period (June 2014).
