High-end laser performance is now available at a fraction of the cost! The LaserMark® LMH Automatic Self-Leveling Rotary Laser offers fast and simple leveling power to handle your toughest outdoor jobs with less manpower.

The unit levels itself via electronic sensors interfaced with motors, eliminating the need for re-leveling or rechecks. No more fussing with manual leveling screws or bubbles; just turn it on and you are ready for work! Plus, the built-in ADS sensor provides peace of mind when working on a busy job site; if the laser’s H.I. (“height of instrument”) is altered due to tripod movement or an accidental bump, the operator is instantly alerted.

The LaserMark® LMH is conveniently paired with our top-of-the-line LD400 Universal Laser Detector and heavy-duty rod clamp, built with all the rugged details and valuable features you need.
