Welcome to the premier site for small wildlife GPS tracking collars. Offered in a wide variety of sizes, shapes and weights we tailor your GPS telemetry collars for your work. Starting with a miniature tracking device capable of acquiring GPS locations in the most difficult conditions we add wireless data download, activity sensors or Smart GPS to enhance data sets and prolong battery life of even our smallest tracking collars. Collars include a VHF transmitter and GPS receiver each working from its own battery. That means peace of mind for you when you are in the field using VHF to locate animals. Our user software is a powerful tool enabling you to program your collars in almost any way imaginable. To read more in depth about this device please click on the How It Works Button below.
