Electronic Dog Repeller
Using the latest ultrasonic technology, the SUPER DOGCHASER uses two ways to repel a dog. The unit produces a discomforting but not harmful high frequency sound (20,000Hz-25,000Hz), audible to dogs but not to humans. Additionally, the unit has a super bright LED flashing strobe that temporarily blinds and confuses the dog. Powered by a 9V battery, the unit is effective up to 40 feet.
Dimensions: 4.75" x 1.75" x 0.75"
