The Wildlife Research Center Magnum Dripper Deer Scent Combo allows a hunter to create an exceptional mock scrape or keep an existing scrape fresh. The Magnum Dripper is an amazing tool that drips the Active Scrape buck lure during the day when the temperature rises, but it stops dripping as soon as the temperature falls again. Combo includes the Magnum Dripper, 4 ounce bottle of Active Scrape and the Scrape Hunting book.
