Stink Finder Super Brite Ultra-Violet Light & Flashlight guickly and easily helps locate invisible sources of pet odor such as per urine, dog urine, cat urine, feces and vomit and make them visible. It features a 9" super brite ultra-violet bulb for large area inspection, a full-size flashlight for easy navigation in dark areas and cordless, battery operation for go-anywhere convenience. If you have a pet on board your boat or even in your home you will be glad you purchased this one. It works excellent as I have used it many times to locate odors and remove them. A great gift for the pet lover !!!
