Locate your pack with the Alpha T 20 dog collars. They feature a durable yet slim frame, designed to fit many breeds with a flexible, user-replaceable strap. When used with a compatible handler (sold separately), these collars can track up to 14.5km. The built-in multi-color LED makes identifying your dog easier even in the dark. You get up to 68 hours of battery life with the basic pack when using dynamic tracking, up to 25 hours with a 2.5-second refresh rate, or you can upgrade to the extended battery pack (sold separately) to get up to 136 hours when using dynamic tracking, which optimizes the rate of updates based on how your dog moves. Plus, when you're charging and connected to your Wi-Fi® network, the collar will automatically install the latest software updates.
