To use, place on a tripod and set it approximately level. The built-in compensator automatically sets the horizontal plane and the laser rotor starts revolving immediately. If tilted or jarred beyond its self-leveling range, the rotation and laser beam stop automatically and a warning light flashes.
This makes it the superior method for dampening the effects of vibrations and rough use to ensure that you're always working with a stable, accurate beam even in extreme temperatures. Laserplane LL500 is designed so that any crew member can easily perform precise, error-free grade checking with reduced manpower and speedier setups. Spectra's waterproof housing ensures maximum productivity anytime, anywhere.
