Building Construction - Lasers & Levels

Elevate the accuracy and efficiency of your construction and grading projects with the Spectra Precision GL720 Dual Grade Laser, complemented by the robust HL700 Receiver. This advanced tool offers unparalleled precision, ensuring that every job is done with the utmost accuracy and professionalism.

The Spectra Precision® RD20 Wireless Remote Display is designed to be used with the LR30W, LR50W and LR60W display receivers. The RD20 mounts in the cab and gives the operator grade information in a convenient location. The operator is free to focus on the work at hand.

The Spectra Precision Laser HL700 Laserometer is a highly versatile laser receiver for basic and advanced leveling and aligning applications. It is designed for general, concrete and site preparation contractors. The HL700 is an easy-to-use tool that accurately measures elevations across the site, and is ideal for use with any rotating transmitter.

The Spectra Precision® Laser level LL500 Laser Level is a one-person leveling system designed for longer range measurements across your entire site. Accurate, stable and reliable, the LL500 features a 1,600 ft (500 m) working diameter which increases productivity by reducing the need for multiple setups on a large job site. The rugged LL500 is self-leveling with built-in out-of-level shutoff that maintains accuracy over the entire work area and minimizes errors. Visible spotting beam determines receiver mounting placement makes it faster to find the on-grade position. LL500 package includes a HL700 Receiver.

The LL300N's fully automatic self-leveling capability provides fast, accurate setup. Rechargeable NiMH battery pack or alkaline batteries keeps the unit working with no downtime due to power loss. Single cross-axis manual slope mode with cross-axis self-leveling allows grade matching for basic slope work, while maintaining accuracy in the cross-slope. The Spectra Precision® LL300N Laser Level features a rugged design with "hard hat" rotor protection that provides superior drop and weather protection. Built to withstand severe drops of up to 3 ft (1 m) directly onto concrete, or up to 5 ft (1.5 m) when pushed over on a tripod means less downtime and cost due to damage caused by accidental drop. Includes Spectra LL300N with HL450 Receiver.

The Spectra Precision GL722 Dual Grade Laser is one of the most advanced grade lasers on the market. The long-range operation, advanced radio remote, grade matching, Planelok, and automatic axis alignment features mean that you can do quick and highly accurate set-ups for any grade application. With the GL722’s powerful, long-range remote control, it takes one person to accurately set up and operate the grade laser. Even grade reverse is done in an instant. You can automatically control all the transmitter’s functions using the remote. Grades can be changed on the fly up to 750 ft (225 m) from the transmitter. With a grade range of ±10% in the X-axis and -0.5 to +25% in the Y-axis, combined with a 3,000 ft (900 m) operating diameter, no job is too small for this laser. Automatic Axis Alignment can done up to 500 ft (150 m) from the transmitter, providing accurate set-up and eliminating the need to climb a ladder to try to align the laser to your grade hub.
