Scent Trax is a new revolutionary drag line system. Scent Trax places a scent trail just like a deer would. No more pulling a string, getting tangled in brush or getting torn off, like old drag lines do. The coarse velcro piece catches and holds scent for better dispersion. ItÆs water resistant liner keeps the scent off your boots and distributes scent on to the weeds, grasses and brush. Scent TraxÆs easy on/off process allows you to hang it from a branch as a scent dispenser when you reach your hunting destination.
