The Spectra GL720 is an automatic, self-leveling construction grade laser with dual grade capability. Featuring +/-10% grade range in the X axis and -0.5 to +25% in the Y axis, the GL720 laser level is ideal for general construction and automatic machine control applications. 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.
With weather-resistant control panel and built-in non-slip carrying handle, the GL720 allows you to work in all weather conditions. This grade slope laser uses NiMH batteries and offers flexible power options, battery life indicator, and wirelessly operated sleep mode that saves power during breaks.
The Spectra CR600 is a handheld and rod-mounted laser receiver that can also be used for machine control. It has 270-degree reception and a highly visible display for use on a backhoe, small excavator or skid steer. Rugged, accurate and easy to use, the CR600 provides high, low or on-grade information for all your grading and excavation applications. With 15-channel linear display and receiver cells with continuous pickup, it provides less dead spot and does not require you to be on-grade to measure.
