Garmin TT 25 Alpha Features The Garmin TT 25 Alpha is built to give handlers real-time location data on a working or hunting dog at distances up to 9 miles when paired with a compatible Alpha series or Pro 550 Plus handheld. GPS-enabled tracking lets the handler check a dog s position on the handheld display without needing line of sight which matters in heavy cover or rolling terrain where a dog can range well out of view. The housing is slim and rugged designed to stay out of the way of a working dog s movement while standing up to the abuse of brush water and repeated use in the field. A one-size-fits-all collar design keeps setup simple across different dogs and collar configurations. Beyond tracking the TT 25 Alpha doubles as a training device offering stim tone and vibration correction modes so the handler can choose the method that fits the dog and the situation. The rechargeable lithium-ion battery pack is rated for up to 68 hours of use between charges supporting long days afield without needing a mid-hunt swap. Its black and orange finish keeps the collar easy to spot on the dog at a glance which helps during retrieval or visual checks in dense cover. Compatible with the Pro 550 Plus and Alpha series systems the Garmin TT 25 Alpha extends an existing handheld setup to additional dogs without replacing the base system.
