Pathfinder is a revolutionary way to mark trails to any location you are trying to get to without leaving all kind of signs to get to your secret spot. You simply spray and type of marking, you want to identify with onto a tree that marks out the trail to your location. Pathfinder can?t be seen in the daytime so there?s no worry. Simply shine your flashlight in the dark and light you way in and out of the woods. Pathfinder will last for months before slowly fading away, leaving no trace and zero harm to the tree. Comes in a 4oz spray can. Size: 4oz. Note: This item is flammable, and can only be shipped UPS Ground.
