4 TRAINING MODES: Our dog training collar offers 4 working modes: shock/vibration/light/sound. Both vibration and shock can be adjusted. The remote control has 1 to 99 individual shock and vibration levels. When using, choose the level that suits your dog, which can help you better control your dog's behavior and help your pet eliminate bad behavior. LIFETIME: The remote control uses advanced transmission technology and does not need to be aimed directly at the receiver. The remote control information can penetrate walls and other obstacles, which is convenient for training your dog in a park or backyard. When your dog swims and dives, the waterproof performance is super good! Made of high quality nylon, the collar is soft and breathable and will not damage your pet's neck like other leather collars. The length of the collar can be adjusted to suit all dog sizes. UNIQUE ENERGY SAVING DESIGN: Automatic sleep function and memory function. The receiver has a sleep power saving function.
