The General Tools LDM3 120’ Laser Distance Measure is designed to replace a conventional tape measure. The LDM3 is faster, safer and more accurate than a conventional tape measure. It takes much less time and only one hand to hold the tool against a wall, aim at the opposite wall and press the button than it does requiring both hands to secure one end of a conventional tape measure, walk the other end to the far wall, write down the reading and retract the tape. The LDM3 offers advanced features, like a midpoint finder to help you accurately find the center of a wall to make sure your pictures, furniture, and other home décor are perfectly centered. The area function provides the square footage of a room or wall so you can easily estimate the amount of paint, flooring, tiles, or other materials needed to complete your project.
