The Hunter's Specialties Blade Driver Scent Delivery System is a super quiet scent delivery system that disperses both cover and attractant scents over a wider area than conventional scent wicks. Powered by 2 AA batteries (included), the device spins a scent-infused, fan-shaped wafer blade to discharge scent by exposing the wafer to a substantially greater surface to air ratio. The Hunter's Specialties Blade Driver comes with one wafer blade, batteries, and a lanyard to hang the unit from a branch or treestand. (replacement wafer blades sold separately.)
