GPS collars are a wonderful tool in enabling us to retrieve our dogs when everything works as Garmin planned within a perfect world. There are several things that can prohibit this: 1) The cost of these systems are quite expensive meaning not everyone  can afford them. 2) The antenna on these collars can brake contributing to a dramatic reduction in tracking range if at all. 3) There is a very  small guage wire connecting the antenna to the transmitter on the collar. Although when designed this wire was built in a manner to protect this wire the best way possible but it still brakes at times making tracking impossible. For these reasons I'm asking that you please don't implement this rule into the running of dogs for hunting.
