DEWALT DW089K Self-Leveling Line laser Review


The DEWALT DW089k Self-leveling line laser is yet another great innovation as far as finding the best laser level goes. What makes this laser stand out from other laser levels is the second plumb line which forms a 90 degree angle intersecting line on the floor and ceiling. This eliminates the need for a second laser level and takes care of all your layout applications in one go.  There is little to almost no need for extra accessories when using this laser, which makes it cost effective and quick and easy to use.

Technical Specs

There is an integrated pivot bracket and universal wall mount which makes it perfect for use during ceiling installation.  The laser is accurate for up to +/- 1/8inches at 30ft and is self leveling for up to +/- 4 degrees.  Single button control panel makes operation easy and hassle free.


The laser is designed with 3 laser beams which include a 90 degree angle plumb line. These specifications are needed for layouts which require a 90 degree layout.  This vertical plumb beam eliminates the need for a second laser level when used in conjunction with the universal wall mount. The micro adjust knob is an extremely important feature as it allows the user to adjust the beam in small increments without having to physically move the device around. A full time pulse mode allows for the use of a line detector which will extend the lasers reach to 165 ft


The lasers over-molded housing is covered in IP54 rated material making it strong and durable enough to withstand extended periods on harsh job site environments.  Water and dust proof as well as knock proof which allows the laser to stay calibrated for a longer period of time.

This is a class 2 laser with an output of 1mW to power its three laser beams.


Thanks to the second plumb line feature, this laser holds a great advantage when it comes to installing acoustic ceilings and drywall applications fast and effectively. Mapping wall and floor layout is a breeze with the three-beam features and even smaller projects like window and door installations are quick and easy.

This is the perfect laser for construction tradesmen or anyone who is thinking of building their own home. The track clearance of over 1-3/4 inches means that there is no need for any additional tools or accessories to lift the laser beam over drywall tracks.
