Description: The automatic self-leveling Spectra Precision® GL700 Series grade lasers help you precisely control difficult tasks like long-range, high accuracy elevation control and fine grading for major construction projects. The GL700 Series gives you the right laser for the right job... from a single grade transmitter to an advanced, long-range radio remote controlled steep grade transmitter. The GL700 Series offers the most innovative collection of features available - Long Range Remote Control, Grade Matching and Automatic Axis Alignment, and - to get you to grade faster and with more accuracy.

The grade laser is an easy-to-use tool that allows you to take accurate elevation measurements with grade up to 1500 ft (450 m) away using a receiver. The exclusive automatic alignment features allow for quick and easy setup. The exclusive temperature and grade compensation systems are designed for superior accuracy so that your grade laser can be used for general construction, machine-control, and applications requiring tight tolerances under all environmental conditions.

Features:

• Better than 5 arc second servo deadband accuracy for demanding high accuracy requirements

• Active temperature compensation provides accurate stable results regardless of temperature changes

• Automatic self-leveling over the entire grade range simplifies setup and ensures repeatable accuracy

• Large displays make the numbers easy to read, even when set-up on a tall tripod

• Intuitive, simple controls makes using the lasers easy to use and easy to learn

• Fully sealed, rugged aluminum housing and protective lens hood allow work in all weather conditions

• Machine Control compatible and works with all laser-based machine control systems

• Multiple rotation speeds - RPMs - allow for optimal machine control performance

• Long battery life and flexible power options keep the unit working throughout the day

• Grade Bump allows simplification of raising or lowering grade remotely

• Grade Reverse mirrors the grade setting with the push of a button

• Field calibration makes it simple to check and adjust the calibration in the field either at the laser or via the remote control

• Advanced functions and long range radio remote control of the GL722 make it ideal for large-scale, high accuracy applications
