Overview for the Spectra GL720 Dual Grade Laser

The Spectra GL720 is an automatic, self-leveling construction grade laser with dual grade capability.

This grade laser has a working range of up to 3,000 feet and can be mounted on a 5/8-11 tripod.

Active temperature compensation gives accurate, stable results regardless of temperature changes. In addition, the Spectra Precision GL720’s large alphanumeric display is visible from the ground even on ten feet tripods.
