AS2 Precision slope laser, great value. The Pro Shot™ AS2 laser level tool is the class leader for delivering value in a precision slope laser.  Dial-in up to a 25% slope, with resolution down to .01%.  That is fine enough to set specified slopes straight from an engineer’s cut sheet on a sanitary sewer project.  This servo self leveling laser won’t let you down, with degrading accuracy as higher slopes are entered, like its competitors.  It is also fully self leveling when slope is dialed-in.   Specifications 2000’ dia., 1000’ rad.
