I have a Sport Dog TEK 1.0 tracking system which I have used for most of my hunting career. there are a total of 4 collars but 2 stopped picking up signal and the other 2 work fine. Hand held has a crack on the screen but works perfectly fine. For the 2 collars and hand held is $250 the other 2 collars I will throw in with it. I think they can be sent to sport dog and fix for a reasonable price. email is
