hi mate you still need a collar to put on the dog like bellman collar etc or how are you going to attatch it to the dog ,in the clip it is showing you how to use it in an avalanche situiation
just a picture of my new pup 3 months old collie greyhound x saluki bull greyhound dont no the percentages not good with that not a very good picture either she wont sit still lone enough
never used the newer one myself but i have been told they are no tany better or accurate than the older ones they are bigger and have no sound which i think would be weird
