This product is a great alternative to our
dog pepper spray. To use this, you press a button which causes a discomforting, yet non-harmful high frequency sound, which is in the range of 20,000Hz to 25,000Hz, which makes it heard by animals but not humans. This is a multi-use tool because there is an extremely bright LED flashing strobe included, which confuses and blinds the dog temporarily. Also, you can use this as a flashlight.
This product can stop dogs from a distance of up to 40 feet! There is also a training setting programmed into this device. One 9-volt batter is required (INCLUDED!).
