The Dewalt DCE088D1G18 12V/18V Cross Line Green Beam Laser.
The self-levelling, green beam laser projects a bright crossing horizontal and vertical lines as well as extended working range for internal applications.
The locking pendulum helps to prevent damage to internal components and there is an integrated magnetic pivoting base with a 1/4in thread. It has a variable blink sequence for manual mode for use with a detector to maintain full brightness and visibility.
The DCE088D1G18 has a visible working distance of 30m or 50m when used with a detector and includes an accuracy of +/-3mm at 10m. A fine adjustment knob allows for precision as well as accuracy while the self-levelling time is as little as 5s.
