Spectra Precision GL422N Dual Grade Laser with HL760 DRO Receiver

This automatic, self-leveling dual grade laser simplifies level, grade, and vertical alignment setups! The GL422N has a working range of 2,600 ft. (800m) and features a Height of Instrument Alert that stops the unit from rotating when jarred to avoid erroneous readings. Selection of Sensitivity ensures accuracy even in windy conditions. The included HL760 Digital Readout (DRO) receiver provides a digital readout of elevation and offers a large laser capture height for fast grade checking and laser readings. The HL760’s ”Fingerprint” function ensures that the receiver only accepts the beam from the laser that it is paired with, reducing errors and conflict when other lasers are being used within close proximity. Grade Match connects different elevations and can calculate and display grade values between two points. PlaneLok automatically locks the beam on the HL760 and keeps it on-grade to eliminate drift or error due to improper calibration or environmental factors. The included RC402N radio remote control allows you to operate the laser from up to 330 ft. (100m) away and features a menu-driven interface to simplify use. Durable and portable, the GL422N survives drops up to 3 ft. (1m) onto concrete, and the energy-efficient design provides long battery life. IP66 dustproof and waterproof. Five-year manufacturer’s warranty.
