Spectra RC602N Radio Remote Control for Spectra GL612N and GL622N Lasers

Control Your Grade Laser from Anywhere on the Job

The Spectra Precision RC602N Radio Remote Control puts full command of your grade laser in your hand—up to 330 feet away. Designed specifically for the GL612N and GL622N rotating grade lasers, the RC602N eliminates the constant back-and-forth trips to the instrument head every time a grade adjustment is needed. Whether you're working a large earthmoving site, a commercial pad pour, or a residential drainage project, keeping your operator mobile means faster setup, tighter grades, and a more efficient crew from start to finish.

Built for Real Jobsite Conditions

The RC602N gives machine operators and grade checkers the ability to dial in elevation changes and fine-tune slope settings without ever leaving their position. That kind of flexibility dramatically reduces downtime on grading and excavation operations where multiple stakeholders need to respond quickly to changing field conditions. The remote's reliable radio signal works without line-of-sight, so terrain, equipment, and crew movement won't interrupt your control. It's a straightforward upgrade that pays for itself in labor savings on the first major project.

Job Applications

Site Grading & Earthmoving: Machine operators can adjust grade references on the fly without stopping the dozer or grader run—keeping production moving and reducing re-work.

Commercial Concrete Flatwork: Finishers and grade checkers can call for elevation tweaks between screeding passes without pulling anyone off the deck.

Residential Drainage & Pad Work: Solo operators benefit most here—one person can manage instrument and grade check across the full lot without repeated walks back to the tripod.

Utility Trenching: Trench crews working at depth can signal remote grade corrections from the trench without disrupting surface operations or requiring a second technician at the laser.

Frequently Asked Questions

Which lasers is the RC602N compatible with?

The RC602N is designed for use with the Spectra Precision GL612N and GL622N rotating grade lasers. It is not cross-compatible with other Spectra or Trimble laser models outside of this series.

Does the RC602N require line-of-sight to operate?

No. The RC602N uses a radio signal rather than infrared, so it operates reliably without a direct line-of-sight between the remote and the laser—even around equipment, structures, or uneven terrain.

What functions can I control remotely with the RC602N?

The RC602N provides full-function remote control, allowing operators to adjust grade and elevation settings on the laser from up to 330 feet away, eliminating the need to manually interact with the laser head for most common field adjustments.

Is the RC602N sold with the GL612N or GL622N, or separately?

The RC602N is available as a standalone accessory. Check your laser kit contents to confirm whether a remote is included, as package configurations can vary. Contact Express Tools if you need help confirming compatibility with your current setup.
