With Birdseye I can look on my Garmin Astro 320 map and determine the easiest way to get my dog back. With the Birdseye I love being able to tell the tall woods from the cut-over and fields. You can see the routes your dogs run the deer and bam your in the hot spot all the time. Great feature for the Garmin Astro tracking system.
