There are several virtues of having a GPS tracking collar on a dog. I like knowing exactly what is happening with my two dogs in the field, all the time. Many of you say your dog is fine without one but wait till something happens and you cannot find the dog! A trap, a deep hole, ran after a deer you didn't see. Heck they can wander off and in a few minutes be gone! Ever loose a pair of dogs for three days? It will tear you up. Luckily I found mine and immediately purchased a GSP tracking system. I even put it on the dogs when I take them fishing. One could fall in and it could be difficult to locate when swimming a few hundred yards away.

When hunting two dogs in thicker cover and one goes on point I check to see where the other one is so I don't accidentally shoot in his direction. If a dog is out of sight without a collar what is he doing? If a hunter has a training/shock/buzzer/vibrate collar he might hit the button to get the dog back, and it turns out the dog is on point!

A gps tracking collar will tell you what the dog is doing and how far away.

That dog is around here somewhere! ( mearns country ):
