Not the collar. I have the collar (didn't leave the dog behind), but I left my handheld controller behind. Looking to see if anyone has an extra controller that I could borrow for a month
I doubt another controller would work with your e-collar, even if the same model you would have to some how re-sync them. If someone has an extra controller laying around, they probably have the collar to go with it.
I do have an old tritronics controller and collar. The on/off button on the collar does not work good, so I got a new unit. You are welcome to it, I'm in north dallas, PM me if interested.
