Garmin · Dog Tracking & Training
The Garmin Alpha® TT 25 Dog Collar in the Dog Tracking and Training Collar configuration is built for hunters and handlers who want reliable tracking plus training support in one rugged, universally sized collar. Its top-mounted, high-sensitivity GPS and Galileo receiver helps keep tabs on a dog’s location, while VHF transmission works with a compatible handheld (sold separately) for tracking and control in the field.
Designed to fit both large and small breeds, Alpha TT 25 also supports training functions through a compatible handheld (sold separately). With dynamic tracking to help extend battery life, bright multicolor LED beacon lights for low-light visibility, and a user-replaceable flex band, it’s made to stay ready for demanding outdoor days.
Navigation
Alpha TT 25 uses a high-sensitivity GPS and Galileo receiver and transmits location via VHF up to 9 miles when used with a compatible handheld (sold separately). Update rates can be as frequent as every 2.5 seconds, helping handlers stay aware of a dog’s position during active hunts and changing terrain.
Training
Paired with a compatible handheld (sold separately), this collar supports 18 levels of continuous or momentary stimulation, plus audible tone and vibration. That flexibility makes it easier to reinforce commands and adapt correction levels to the situation without changing gear in the field.
Battery
Dynamic tracking adjusts based on a dog’s movement to help optimize battery life. With the standard battery pack (included), the collar provides up to 68 hours using dynamic update rate (default mode). It also supports an extended battery pack (sold separately) for longer runtimes when needed.
Alpha TT 25 is designed with a rugged yet slim build that’s universally sized to fit large and small breeds. The collar features a user-replaceable flex band intended to stand up to tough outdoor environments, and it carries a 1 ATM (10 meters) water rating. A rechargeable lithium-ion pack powers the collar and is user-replaceable, with charging handled through the USB-C interface.
Bright, multicolor LED beacon lights help make the dog easier to identify and follow in low-light conditions. When used with a compatible handheld (sold separately), the beacon lights can be remotely activated and colors can be changed, helping handlers quickly distinguish between dogs or improve visibility as conditions change.
Alpha TT 25 pairs with Garmin dog tracking handhelds, including the Alpha® series and Pro 550 Plus (sold separately). For maintenance, the collar can receive automatic software updates when it is charging and connected to a network using Wi-Fi® technology, helping keep the device current without adding extra steps before heading out.
