Astro can track up to ten dogs per receiver at once, and the collar gives location updates every five, 10, 30 or 120 seconds (user selectable). Battery life is 17-48 hours (based on update rate) on the rechargeable DC 40 collar and 24 hours on the Astro 220 receiver, which is powered by two AA batteries. Both the DC 40 collar and the Astro 220 receiver are waterproof.
The Astro also has a map page to illustrate where a dog is and where it has been – in relation to the hunter – and allows hunters to determine if they have covered nearby ground. Garmin’s unique Covey Counter™ lets hunters mark the precise location, time of day, and elevation where they encountered their quarry – and users can easily note the number of birds flushed and how many were taken.
The Astro has a microSD card slot that allows users to insert optional pre-programmed topo maps or road maps, which can be invaluable in an unfamiliar area. Highly-detailed 24K topo maps give hunters an idea of the most productive areas to hunt, while road maps feature the same basic functions as an automotive GPS navigation unit – even in rural areas. The optional road map data can also give turn-by-turn directions to motels, gas stations, restaurants, and even veterinarians.
The new DC 40 collar is included as part of the Astro GPS Dog Tracking system. For those wishing to upgrade from a previous generation of collar, the DC 40 can be purchased separately.
