This Garmin TT 15 Dog Device Collar lets you add another dog (up to 20 dogs) to your existing Tracking & Training Sytem Alpha 100 GPS transmitter. The TT 15 is also compatible with Astro 430 and 320 for tracking mode 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 9 miles away. The TT 15 collar comes with a high-sensitivity top mounted GPS and GLONASS satellite receiver for safe, secure and more effective tracking, even where Internet and cell phone service isn’t available. The polyurethane-coated collar strap is 1 " x 27", adjustable and will fit dogs with a neck diameter of up to 24".


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 or at night.


TT 15 ships with a 1-inch red collar strap. Replacement straps are available in multiple colors (Want a different color?  Let us know).


Note: This collar does not work with the Astro 220. The TT15 is only compatible with the Astro 430, Astro 320 and the Alpha 100. TT 15 can be configured for operation with either handheld but cannot be tracked simultaneously by both the Astro 430 and 320 at the same time.
