EASY TO SET UP. Locate a tunnel using a stick or the Swissinno probe. Cut a hole down into the tunnel. Insert the trap. Pull the handle to set the trap. Job done! NEEDS MINIMAL STRENGTH to set the trap, and it's done in seconds! Pull the handle out to its full extent and the trap is set ready to strike CATCHES GOPHERS, VOLES AND FIELD MICE IN EITHER DIRECTION and gives a visible above-ground signal of a capture (the handle drops back into the trap), so you don't have to continually dig up the trap to check.
