Kapro Tools presents its 873G Prolaser Vector Green Laser Level. The 873G is comprised of a green beam with a wavelength that is more easily detected by the human eye to see than a red beam, the company stated. This allows the beam to be seen over a greater distance, up to 200 ft. using a detector. It also features an outstanding accuracy of 0.0002/1 in., which is less than 1/4 in. at 100 ft.
