Product Description

The Spectra GL622N Dual Grade Laser with RC602N Remote and CR700 Receiver delivers advanced slope and machine control in one kit. Offering automatic self-leveling and grade capability up to 25% on both axes (not simulatenaously), the GL622N is ideal for applications like ramps, parking garages, sports fields, drainage, and steep excavation. With 1/16 in accuracy at 100 ft and 2,600 ft operating diameter, it provides unmatched precision on even the largest sites. The RC602N remote extends control up to 150 m, allowing slope adjustments from anywhere on the jobsite.

This bundle includes the CR700 Combination Receiver, a versatile option for both rod-mounted and machine-mounted applications. The CR700 provides numeric elevation readout, bright LED indicators, and selectable accuracy deadbands, making it ideal for small excavators, skid steers, and backhoes. Ruggedly built with IP67 waterproofing and 3 m drop resistance, it withstands harsh environments while delivering reliable grade information in real time.
