This patented dripper is the deadliest method known to keep a scrape fresh and working. The ULTIMATE SCRAPE-DRIPPER drips your lure only during the day to make sure the buck works the scrape during the day. Activated solely through the rising temperature, this unique unit tells the buck that a doe came by during the day. Unit also shuts off at night or during rain when temperatures are not rising. This allows the user to pattern the buck. Will operate about a week on 1 oz. of scent. Effective on both natural and mock scrapes. Scent not included. Protected under the following U.S. patents: 5,220,741 - 5,279,062 & 5,361,527.
