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 and Astro 430 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.
