Garmin TT 15 Extra Collar

The TT 15 track and train dog device with collar is a top-mounted, high-sensitivity GPS/GLONASS receiver that uses 18 levels of continuous and momentary stimulation plus audible tone and vibration activated from the Alpha® 100. Compatible with the Astro® 320 for tracking only.

Rugged and water resistant to 10 meters, this tracking and training dog device is tough enough to run wherever your dog runs, up to 9 miles away. The stimulation features let you train each dog separately -- traditional stimulation allows you to make quick changes (low, medium or high) within a predetermined stimulation level (1-6) whereas linear stimulation allows progressively more stimulation from levels 1 to 18.

TT 15 units, when sold separately, ship with a 1-inch red collar strap. Replacement straps are available in multiple colors (sold separately).
