Hound Recovery Outdoors All New Xtenda Range Backpacker Antenna. Compatible with the Garmin/Dogtra Pathfinder GPS Tracking Systems. The Backpacker comes with 10’ of coax and has the nice SMA connector for easy on and off your Garmin or Bluetooth device. This was designed by Myself (Wade) and my Co Owner Rickey Prince, that passed away in April 2020. Custom built and sent out over the USA to be tested in hunting conditions. Thanks to Trevor Britten for the Design of the Backpack Harness and his testing in Michigan. These are built for Hound Hunters who have to walk, or horseback, or even hunt out of boats, and have to walk a long way to retrieve their hounds. Super lightweight with ground plane technology to boost your tracking ability. The harness has adjustable straps that can even be strapped on to your Backpack if preferred. Protect what you Love!!!
