T 5 and T 5 mini dog devices with collar are top-mounted, high-sensitivity GPS/GLONASS receivers that use LED beacon lights activated from Astro 320 and Alpha 100. The lights work in low-light conditions and at night, and are visible up to 100 yards away.
Rugged and water-resistant to 10 meters, these tracking-only dog devices are tough enough to run wherever your dog runs, up to 9 miles (for T 5) or up to 4 miles (for T 5 mini) away. T 5 ships with a 1-inch blue collar strap, and T 5 mini ships with a 3/4-inch blue collar strap. Replacement straps are available in multiple colors (sold separately).
