Garmin T20 Collar Compatible with Alpha 300, 300i 200, Alpha 200i, Alpha100 & Astro 430 (AU model only) Garmin T20 dog collar has a top-mounted, high-sensitivity GPS and GLONASS receiver, so you can track your dog from up to 14.5 kilometres away. It features a rugged design — water-resistant to 10 metres (1 ATM) — so it’s tough enough to run wherever your dog runs. Plus, with up to 80 hours of battery life and 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 90 metres away, the lights work in low-light conditions and at night.
