Using the latest ultrasounic technology, the SUPER DOGCHASER uses two ways to repel a dog!
One is the discomforting, but not harmfu,l 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.
Also has a training setting.
Requires one 9 volt battery and can also be used as a flashlight!
