I have a new set of the 9 dog collars and have only used three (3) of the nine (9) collars, other six never been put on a dog. According to the Garmin Company they will hold up for 4 miles, I never have tried this distance. They nice and lighter in weight than my old T.T.G3 set. When I found out that they were not going to be anymore batteries, made for the G3, I jumped the gun, bought this as a two dog set,, like it real well, so I bought seven (7) more New collars form Oakey, he set them up for me and I have never use them they still in the new boxes
I found some new batteries, for my old T.T's so this set will be for sale,, will go the the best Offer
