I have a Sport dog 2500 e-collar system. I have two collars with beepers on them that can be controlled by the transmitter. I also have two more add on collars that are brand new. The receiver and one collar have new batteries. I have a holster for the transmitter as well. I am selling the transmitter, 4 collars (2 of them new), 2 beepers, and holster. I am asking $550.00 obo for all of it.
