Although the dog tracking GPS system from Garmin looks to be unnecessary for tracking dogs, (maybe its main purpose is for hunting dogs) I can recall countless times when I lost my dog in my neighborhood, only to find him 20 minutes, happy after his little lone-trip.
Now, this dog tracking system can be great if you tend to lose your dog a lot.
The Astro GPS Dog Tracking System requires very little configuration straight out of the box, and is extremely simple to use. Once the transmitter and receiver acquire a GPS signal, the receiver automatically lets users know the location of their dog. Unlike old radio telemetry collars, the Astro features a dog page that shows the precise direction and distance to a dog – even indicating if it is running, on point, or treeing quarry – and does it all without the annoyance of beeper collars. Unlike cellular tracking systems, there are no subscriptions or setup fees required to use the device.
