Regardless of the breed of dog and its size, Alpha ^® T 20 K is the light, robust and universal collar designed to help you train your dog as best as possible.

The top-mounted, high-sensitivity Galileo and GPS receiver monitors your dog's location, while the Alpha ^® T 20K Collar transmits it via VHF up to 10 kilometers away, with frequent updates up to 5% seconds, when used with a compatible handheld (sold separately).

The sturdy yet slim design is one-size-fits-all to fit both large and small sizes.

Get long battery life with dynamic tracking based on your dog's movements.

The collar features a replaceable flexible sheath that can withstand the harshest outdoor environments.

This collar features multi-color LED location markers to help you identify and track your dog in low-light conditions. These beacons can be activated and modified remotely via a compatible handheld (sold separately).

When using dynamic tracking, you can get up to 68 hours of battery life with the standard battery and up to 136 with the extended battery (sold separately).

Download automatic software updates while charging and connecting to your Wi-Fi network connected to your Alpha ^® T 20 K.

The Alpha ^® T 20 K GPS dog collar can be easily paired with Garmin dog tracking handhelds, such as the Alpha ^® (sold separately).
