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. Helps stop the approach of unwanted dogs up to 40 feet. Has a training setting to help you correct your dog's behavior. Can Also be used as a flashlight. Features: • Dimensions: 4 3/4" x 1 3/4" x 3/4" • Requires one 9 volt battery (not included)
