Who Is This Collar For?
The Garmin Alpha® TT 25 is built for hunters and dog handlers who already own or plan to pair with a compatible Garmin handheld (Alpha series or PRO 550 Plus, sold separately). It's well suited to upland hunting, tracking working dogs across large open ground, and anyone who needs reliable location data alongside hands-off training control.
The top-mounted GPS and Galileo receiver keeps constant tabs on your dog's location, transmitting via VHF up to 14.5km when paired with a compatible handheld, while 18 levels of stimulation, tone, and vibration give you a full range of training options in the field.
One of the main advantages of the TT 25 is its universally sized, slim design, the same collar fits both large and small breeds, so you're not locked into a specific size or shape.
It's worth noting the TT 25 is an add-on collar, not a standalone device, it requires a compatible Garmin handheld to unlock tracking and training functionality. Someone building a full setup from scratch may want to pair this with a handheld such as the Garmin Alpha 300 or Alpha 10.
