Grave Digger Scrape Mate is soil impregnated with CODE BLUE buck urine that you shake onto a scrape or mock scrape. Use all season long as a curiosity or infringement scent. Time release scent stays potent for up to 30 days. Scrapes are one of the greatest ways to ensure bucks revisit a spot day after day, but the challenge is keeping the scrape fresh for a long period of time. Grave digger with TRS (time released scent) is a patented process that uses high-quality soil impregnated with buck urine collected from an individual buck. Pour it into a scrape or mock scrape then cover it up. Grave digger blends with the soil attracting bucks and allowing them to work the dirt freely and naturally. Moisture forces the scent to the surface keeping the scrape active for 30 days. Rain actually makes it stronger. Use grave digger scrape mate all season.
