I see your point, but this chip don't work like the old the 1, the old chip works by moving the scanner over the dog, then blips when your over the chip giving you the place where the chip is inplanted, this is not good, also the old chip was put under the skin of the dog so could move or be removed.
THE NEW CHIP IS PUT IN BY DEEP INTERMUSCLAR SHOT, AND THE SCANNER WILL PICK THE DOG UP WITH IN A ONE FOOT RADIUS OF THE DOG.
