Whenever users are trying to make highly clear dot alignment on various targeting surfaces, not simply used for quite close distance, it would be quite easy work to use Berlinlasers red laser diode module. After quite easy connect with a DC input power supply and proper use of inner metal heat sink cooling system and APC, ACC driving circuit board, which is able to work with super nice thermal emitting and highly stable red dot projection in continuous work. Whenever red dot laser gets correct installation and adjustment, within the maximum work distance of 25 meters, it achieves the most satisfied dot positioning result for all industrial dot measuring works effectively.
