The Garmin TT 15 Mini Dog Device 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 Alpha 200i, Alpha 200,  Alpha 100, Alpha 10 or the PRO 550 Plus. Compatible with Astro® 430 and 320 for tracking only.

Rugged and water-resistant to 10 meters, the tracking and training dog device with collar is tough enough to run wherever your dog runs, up to 4 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. You can remotely operate the LED beacon lights, built in to the dog device, to help locate your dog in low-light conditions.
