Trimble‘s Spectra Precision Laser LG20 Crossbeam Generator is a one-person hand tool that can be used to replace a level, square, plumb bob, chalk and optical instrument for faster completion and increased accuracy on the job site. This self-leveling, universal accessory operates in both horizontal and vertical modes in a variety of interior and general contractor applications. The LG20 Crossbeam Generator can also withstand a drop of up to 3 feet directly onto concrete. The laser diode emits a beam that can be seen at a distance of up to 100 feet visually.
