The Ultrasonic Remote Pet Trainer is a small, hand-held device designed to assist you in the training of your dog or cat.
Ideal for correcting misbehaviors, it takes advantage of your pet's sensitive hearing in the ultrasonic frequency range, beyond the range of human beings.

The Trainer has only two buttons: Positive Tone for reward, and Ultrasonic Tone for correction. It's that simple! This has been a popular item with mail carriers and meter readers to repel unwanted advances from neighborhood dogs. Excellent for basic obedience training including: Sit, Stay, Come, Heel, Down and Break.
