The CAMO MARKSMAN is a tool designed for concealed edge fastening of wood decking. The weight of the device is only 2 pounds. Essentially, this tool is an adjustable guide that allows the screw to be driven more concealed than the traditional way into the wood flooring during installation. The guide allows the screw to be driven in so that the surface is unaffected - the installation is into the edge of the board. The device is suitable for treated boards, pvc flooring and similar materials. The guide has presets for different types of boards - thicknesses from 5-1/4 to 5-3/4 inches. The tool also automatically adjusts the interval. The nozzle avoids cracking and splitting of the material.
