These lightweight receivers allow dogs to be trained at home or at the park-up to 100 yards away. 10 levels of correction, plus a tone-only stimulation. Weather resistant hand held transmitter. Lightweight, waterproof receiver. Operates on a common 9-volt battery and Two (2) 3-volt batteries.
I own the remote correction collar. It does work, however is very cheaply built. I also have problems gettting the batteries in the collar and have to use something to guide them in. The remote cracked on the inside were the battery goes and was always losing connection. This was like this after the 3 time of use. We had to put a piece of paper or cardboard in it to hold it in place.
