Multi-Channel & Customizable Control
Choose between 3 receivers with one remote and four training modes: Shock/Vibration/Light/Sound. Control your pet up to 330 yards in an open field and 165 yards in a field with tons of obstacles.
You could adjust the level of vibration mode and shock mode from 1 to 100. The LCD screen and blue backlit show the modes, levels, and channels in the dark, avoiding the wrong operations.
Adjustable and Versatile
The collar length is 27.5in, and it can be adjusted to fit small, medium, large dogs, and puppies, 15lbs or larger. The receiver is 100% waterproof so your dog can swim or walk in the rain with it.
