Garmin's T 5X dog collar has a top-mounted, high-sensitivity GPS and GLONASS receiver, so you can track your dog from up to 9 miles away. It features a rugged design that's water resistant up to 10 meters, and features an impressive 80-hour battery life with a sleep mode to remotely put the device to sleep, you can focus on the hunt instead of the next charge. LED beacon lights, activated from your compatible handheld, help keep track of your dog in the field. Visible up to 100 yards away, the lights work in low-light conditions and at night.
