When I am trying to get clear enough cross line targeting result, I just cannot control myself to recommend other users to try Berlinlasers green cross laser alignment. It is a very bright beam emitting cross line laser device, on basis of its good use of 532nm green DPSS laser system, it is easily obtaining high brightness two perpendicular green lines with accurate 90 degree at quite long distances.
This green cross laser alignment gets advanced configuration of glass coated lens, within its selectable optic lens degree of 10, 15 and 110 degree, cross line source is available with different dimension. It is much more advanced and easier to operate than any other manual cross line drawing tool. According to exact work distance, height, and other working environments, this cross line laser can be easily selected with output power and optic lens degree, getting quite easy and low labor force input cross line alignment all the time.
