Garmin gps device collars TT 15 and TT 15 mini track and train dog devices with collar are top-mounted, high-sensitivity GPS/GLONASS receivers that use 18 levels of continuous and momentary stimulation, plus audible tone and vibration activated from Alpha® 100. Compatible with Astro® 320 for tracking only.
Rugged and water-resistant to 10 meters, these tracking and training dog devices are tough enough to run wherever your dog runs, up to 9 miles (for TT 15) or up to 4 miles (for TT 15 mini) away which are garmin device collars. 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 ships with a 1-inch red collar strap, and the TT 15 mini ships with a 3/4-inch red collar strap. Replacement straps are available in multiple colors
