    Overview for Spectra Precision CTO-GL720 GL720 Dual Grade Laser

    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.

    Configuration Options

    • CTO-GL720: With HL700 Laser Receiver

    The Spectra HL700 Laserometer provides a digital readout of elevation that shows exactly how far you are from on-grade and allowing quick elevation checks without moving the rod clamp. This laser detector has highly visible LED display and features an anti-strobe sensor that stops construction lights from setting off the receiver and makes it easier to identify true laser beam signals. The readout is displayed on dual sided LCDs and selectable units of measure are displayed in millimeter, centimeter, feet, inches or fractional inches. 

    • CTO-GL720-10: With CR600 Laser Receiver

    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.

         Active Temperature Compensation gives accurate, stable results regardless of temperature changes.
