"This mini no-bark trainer has a built in rechargeable battery system. The unit delivers 1/2 second corrective stimulation with automatic three-second safety delay and built in Magnetic ON/OFF, while the digital numeric display shows 8 different intensity levels. The Vibration Sensor only picks up vocal cord vibrations eliminating unnecessary "shock" from extraneous noises or dog's tags. The unit is completely waterproof and fully adjustable color for both small and large dogs."
