Product Description

Overview for Spectra Precision CTO-GL710 GL710 Grade Laser

Accurate up to 3,000 feet, the Spectra GL710 is an automatic, self-leveling single grade construction laser suitable for site preparation, trenching, pipe laying and machine control. The GL710 laser level features -0.5 to 25% grade range on a single axis and self-levels to 10%, making it ideal for general construction applications. You can mount this device on a 5/8-11 tripod.

The Spectra Precision GL710’s large alphanumeric display is visible from the ground even on ten feet tripods. It also has active temperature compensation to give accurate, stable results regardless of temperature changes.

With fully sealed aluminum housing and protective lens hood, the GL710 laser is dustproof and water resistant. It also has a battery life indicator and operated sleep mode that saves power during breaks. This grade slope laser uses NiMH rechargeable batteries.

Configuration Options

  • CTO-GL710: With HL700 Laser Receiver

Ideal for use with any rotating Spectra grade laser, the HL700 laser detector features a digital readout of elevation that provides a numeric display of +/-2 inches. The readout is displayed on the large front and rear LCDs and shows exactly how far the elevation is from on-grade. Accurate measurements can be made without moving the rod clamp and selectable units of measure can be displayed in millimeter, centimeter, feet, inches or fractional inches. With a large five-inch reception height, the Spectra HL700 laser detector acquires the beam quickly and makes it easy to stay on the beam.

  • CTO-GL710-10: With CR600 Laser Receiver

With an operating range of 270 degrees, the included CR600 laser receiver indicates grade elevation information for general, concrete and site preparations. It can be used as a handheld or rod mounted receiver for a wide range of applications, or as a machine control mounted receiver for use on a backhoe, small excavator or skid steer loader. With 15-channel linear display and receiver cells with continuous pickup, it provides less dead spots and does not require you to be on-grade to measure. The CR600 laser detector also has bright red and green LED elevation indicators, which ensure high visibility in poor lighting or bright sunlight.

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