Using our T 9 collar device (sold separately or as a bundle) to transmit each dog’s location as often as every 2.5 seconds, Astro 900 is quick to pinpoint the track they’re following — even when they’re on the run. On the Astro 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. For help in keeping the big picture in sight when tracking multiple dogs, it’s easy to auto zoom the map page, so all dogs can be seen on the display at any time. Dogs that are too far away to fit on the map’s current zoom scale can be notated on the display’s margin in the direction of the dog’s location. To reduce visual clutter on the map, you can toggle between 'show all,' 'show some' and 'show none' — selecting the duration that each dog’s track is viewable on the display.
