This patented deer scent dripper from Wildlife Research Center is the deadliest method known to keep a scrape fresh and working. The Magnum Scrape-Dripper drips your buck lure only during the day to make sure the buck works the scrape during the day. This allows the user to pattern the buck. Drips daytime only, to get bucks to come during daytime hours. Will operate for 2 - 3 weeks on 4 FL OZ of scent depending on conditions. Gradually intensifies scent output to get bucks even more riled up! Normally shuts off during rain & bad weather, so it saves your valuable scent.
