I have a Dogtra 2500 dog collar for sale. I've used it for 3 years. It has some typical wear from the dog running through brush. It has been a great collar, and have had no problems at all. Everything works as it should. Only reason of selling is that I got another pointer, and bought the same thing only in two dog model. For more specifics go to the webisite above. Asking 235 bucks.
