that sorta all depends. first off how many dogs are you wanting to track at any givin time. next what type of coon hunting do you do. hunt from the truck or walk all night going to the dogs treed and thenrecasting them from the tree? also what kind of terrain are you in? quick track are a nice unit and the 6000 is real nice, but i wouldnt over look wildlife and LL tracking systems(which are the two i have in my dogbox at the time). my next purchase though will be a tracker maximum 5000 because of its handiness(if thats a word) they dont quite have the range of the larger units but my dogs rarely get over 5 miles away and they track that far. hope this helps
