GARMIN ALPHA TT25

Track your pack with the Alpha TT 25 dog collars.

They feature a durable yet slim frame designed to fit multiple breeds with a user-replaceable flexible strap. When used with a compatible controller (sold separately), these collars can locate up to 14.5km away and send training commands such as stimulation, tone or vibration when using the Alpha TT25 collar. The built-in multi-color LED makes identifying your dog easier even in the dark. You get up to 25 hours with a 2.5 second refresh rate, up to 68 hours of battery life with the basic pack when using dynamic tracking, or you can upgrade to the extended battery pack (sold separately) to get up to 136 hours when using dynamic tracking, which optimizes rate updates based on how your dog is moving. Plus, when you're charging and connected to your Wi-Fi® network, the collar will automatically install the latest software updates.
