Electronic Dog Repeller
Using the latest ultrasonic technology, the SUPER DOGCHASER uses two ways to repel a dog. One is the discomforting but not harmful high frequency sound (20,000Hz-25,000Hz), audible to dogs but not to humans. And, the second is a super bright LED flashing strobe that temporarily blinds and confuses the dog.
