Garmin Alpha TT25 Dog Training Collar + Power Bank

GPS tracking collar with 9-mile VHF range

The Garmin Alpha TT25 is a rugged GPS collar built for hunters and field trainers who need real-time location data on working dogs. It transmits position updates as often as every 2.5 seconds via a high-sensitivity GPS and Galileo receiver. Integrated multicolor LED beacon lights assist visual tracking in low-light conditions. A compatible Garmin handheld device is required to receive and display the transmitted location data.

Training functions require a paired handheld

The collar delivers 18 levels of continuous or momentary stimulation plus audible tone and vibration cues. All training controls are accessed exclusively through the paired handheld unit; the collar itself has no onboard buttons for correction. Dynamic tracking adjusts update rates based on the dog’s movement to conserve battery life during long outings. Without the handheld, the unit functions only as a beacon and cannot issue training commands.

Replaceable battery packs enable extended field use

The included power bank provides a portable way to recharge or swap battery packs without returning to mains power. Battery packs are user-replaceable, letting you carry spares for multi-day trips. The collar fits both large and small breeds with its universal flex band, which is also replaceable. Automatic software updates occur over Wi-Fi when the collar is in range of a known network.
