The Garmin DC 30 slips around your dog's next, counterbalancing the electronics to keep an antenna high in the air, the better to broadcast your pup's location to the "Astro" handheld GPS unit. By default the DC 30 sends a blip every five seconds for up to 17 hours; increasing the interval increases battery life — up to 36 hours for 30-second spurts. Depending on the terrain, you'll be able to track your dog from up to seven miles away.
It's designed for hunters, of course. Most of us don't need a $200 collar and a $650 GPS unit to let us know that, yup, the dog's still in on the couch drooling all over a copy of Field & Stream.
While we're on the subject, I'd like to make a request to other gadget manufacturers: please provide more images of your gear being used by dogs. That your product is not specifically designed for canine use is inconsequential.
