Garmin Beeper Battery Pack for Alpha T20 & TT25 Dog Collars

Gamin Beeper Battery Pack

The Garmin Beeper Battery Pack delivers powerful sound and long-lasting performance for your Alpha T20 and Alpha TT25 dog tracking collars, helping you keep tabs on your dog in the field with both audio and visual cues.

Designed with a built-in high-output speaker, this beeper battery pack lets you hear your dog’s movements from a distance. Choose from five selectable sounds — single beep, double beep, triple beep, low beep, or hawk — to indicate running, pointing, or stationary behavior. You can also manually activate the sound at the push of a button when using locate mode.

With up to 78 hours of battery life in dynamic tracking mode, this pack provides dependable runtime for extended hunts and training sessions. Integrated LED beacon lights can be activated from your compatible Garmin handheld, making it easy to visually track your dog in low-light conditions.

The beeper battery pack attaches easily to compatible collars and is fully controlled from your Alpha 10, Alpha 200, Alpha 300, or PRO 550 Plus handheld device (sold separately).
