SPECTRA GL412 Precission Laser Level

SPECTRA GL412 Precission Laser Level is a rugged, automatic self-leveling laser that performs level, grade and vertical alignment. This construction rotary laser has a 2,000 foot range and includes a CR600 laser receiver with 270-degree reception for fast and easy machine control display.

With grade capability of –10 to +15% on a single axis, the GL412 grade laser self-plumbs in the vertical position to allow bolt installation, form, tilt up, and curtain wall plumbing. It is ideal for agricultural and construction applications with its self-leveling accuracy of 1/16th inch per 100 feet. You can also mount this device on a 5/8-11 tripod thread vertically or horizontally.

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. The CR600 laser detector also has super-bright red and green LED elevation indicators, which ensure high visibility in poor or bright sunlight.

Spectra Precision GL412 has a mask mode that allows you to turn the laser beam off electronically on up to 3 sides of your choice to eliminate interference with other crews. It also features an electronic leveling vibration filter that dampens vibrations typically experienced on tall tripods, in high winds or on high vibration worksites. Incorporating automatic temperature and grade compensation, this Spectra laser level delivers highly accurate results in any weather or geographical location. It also includes a RC402 radio remote control that gives you full control of the laser from up to 330 feet away.

With an IP66 rating, the GL412 laser level is protected against dust and water jets from any angle and can survive drops of up to three feet high on concrete! This grade slope laser uses four NiMH batteries and works up to 55 hours.

This Spectra grade laser package comes with a CR600 laser receiver, remote control, rod clamp, carrying case, NiMH rechargeable battery pack, charger and a 2-year manufacturer’s warranty.
