The DeWalt DW083K is a self leveling 3 beam laser powered by AA batteries. It is accurate to ±0.2mm/m. It is self leveling up to 4 degrees surface angle with the pointer able to be rotated 180 degrees, it has a one button operation - for fast and easy operation of the laser.
The pendulum locks when in 'off' position and the focused laser beam keeps the laser dot small, even over long distances for improved accuracy and visibility. Location magnets allows the pointer to be used on metal track or with wall bracket, with the industrial design allows pointer to be placed over track. It also has a 1/4in standard tripod connection.
