The RP4000 Self Leveling Plumb/Cross Laser represents one of the best values we’ve seen in a while. For pros and do-it-yourselfers alike, this is one tool that is priced as low, or lower than many of the non-rechargeable competition. The tool actually sits inside of a plastic jacket that contains a threaded tripod mount. Once the tool is lifted a bit and “unlocked”, the level is able to self-level and you can get effective results in any of the three modes. The modes are a combination crosshair/plumb bob mode which fires a horizontal and vertical beam as well as top and bottom lasers for use as a plumb bob. The second mode fires only the horizontal beam and the top dot. The third mode shoots a vertical beam with the bottom dot. For setting up cabinets and interior work this is going to be a no-brainer and a real go-to tool.
