Pet Safe Deluxe Big Dog Trainer Deluxe NIB Red Sz L Vibration Humane solution

Big Dog Trainer by Pet Safe Deluxe New in box. Made by Radio Corporations in Knoxville, Tn. Says it is made is USA and China on the box. Not sure of the color of the collar since it has never been opened, but the picture shows a red collar. Has range for up to 100 yards, water resistant and has 8 levels on the transmitter. Claims to be one of the most humane trainers out there. I have seen this work on dogs that are very stubborn and need encouragement to obey.
