The PLS HVR-505R is an automatic-leveling horizontal/vertical rotary construction laser level. When we say "horizontal/vertical", I mean you can lay this laser on it's side and use it vertically as well. When used on it's side, the rotary laser beam produces a vertical plumb reference line. This HVR500 has capabilities of dual manual slope which means you can use it to do grade (realize that this is outside of the automatic-leveling mode). The HVR-505R has both a plumb-up and a plumb-down beam, as well as its rotary level beam. The plumb-up and plumb-down produce a "dot" on the ceiling and "dot" on the floor, which is directly plumb up and down from the rotary level beam. Very bright green beam. Excellent tool
