Losing your dog and having to waste valuable time tracking him down is a problem for most hunters. Well not anymore! Garmin's Astro is an extremely sensitive GPS dog tracking system that will allow you to let your dog do the hunting while all the time knowing exactly where your dog is. Imagine being able to pinpoint his exact location without even being able to see or hear him. As quickly as every 5 seconds, the DC-30 transmitter attached to your dog sends his location to your hand held. You can also see the trail he took to get there. Switch to the Dog Tracker view and determine if your dogs is running, sitting, on point, or treeing. The Astro can also be set to send you an alarm when you dog goes on point.
