Spectra HV101 Multipurpose Construction Laser Level with RC601 Remote Control, Wall Mount, Laser Glasses and Heavy Duty Carry Case The Spectra Precision HV101 Self-Leveling Laser has 100 feet interior range that extends up to 1,000 feet when used with a laser receiver. It has an accuracy rate of ±1/8 inches at 100 feet and self-levels within ±5 degrees. The HV101 laser level can be mounted on a tripod either vertically or horizontally and includes a plumb reference point, making it perfect for acoustical ceiling and drywall installation. It is also great for interior squaring, vertical, and 90-degree layout, along with any other indoor finishing work.

The Spectra HV101 laser level features four rotation speeds: 0, 50, 200, and 600 RPMs, plus five preset angles for fast setup. It also works well outdoors with septic tank installation or other elevation transfer work, as well as short-range general construction aligning and leveling.

The included RC601 remote control offers scanning, speed, and alignment controls for fast one person setups. It allows the single-axis manual slope matching feature to be used up to 100 feet away from the laser.

The Spectra HV101 automatic self-leveling laser is water-resistant and maintains accuracy even after a three-foot drop. If it has knocked out of level, the beam and rotation automatically shut off and a red LED light flashes. This Spectra Precision laser comes with two D-cell alkaline batteries that provide up to 50 hours of continuous use and its LED light flashes red to indicate low battery power.
