Are you looking for a laser to help you with a lot of different applications? Because FUTECH’s 3D cross line lasers project continuous lines on the floor, walls and ceiling, they can be used in a very wide-ranging way. They are chosen for flooring, tiling walls, fitting false ceilings, placing switches or lights at the same height, fitting cabinets to walls, etc. Those wishing to use their 3D cross line laser outside occasionally can get started with the receiver mode and an optional receiver.
