Garmin's Astro is a unique system that pinpoints your dog's position and shows you exactly where he is, even when you can't see or hear him. The Astro system includes a bright color-screen handheld GPS device and the rugged, all-weather DC 30 collar. The collar has an integrated GPS transmitter and is specially weighted so the antenna will always point to the sky for optimum signal.

To get started, just take the Astro outdoors and turn on the handheld unit and transmitter to acquire GPS satellite signals, then attach the DC 30 to your dog. 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 Astro handheld has all the features of Garmin's top-line handheld outdoor devices.

With optional detailed city street maps, you can search for over six million points of interest and create a route on roads with exact turn-by-turn directions. Contact: Garmin; (913) 397-8200; www.garmin.com.
