Spectra Precision HL760-NB Laser Receiver (Radio) NO Bracket

High-Performance Laser Detection for Demanding Jobsites

The Spectra Precision HL760-NB is a professional-grade laser receiver engineered for accurate grade and elevation control across extended ranges. Designed for contractors who already have a compatible rod clamp or machine mount, this receiver-only configuration delivers all the detection power of the HL760 platform without the added cost of a bundled bracket. Whether you're expanding a multi-crew operation, replacing a lost or damaged receiver, or outfitting machine-controlled equipment, the HL760-NB gives you reliable performance you can count on at the end of a long day on the job.

Overview and Jobsite Applications

The HL760-NB is built around a large detection window that captures the laser beam quickly and accurately, even in bright sunlight or dusty conditions. The intuitive digital display and audio/visual indicators let operators read grade information at a glance, reducing the back-and-forth communication that slows down crews. Compatible with Spectra Precision rotary lasers, this receiver integrates seamlessly into existing grade control workflows for earthwork, pipe laying, concrete flatwork, and general site development. Its rugged housing stands up to the drops, vibration, and moisture exposure that are part of everyday contractor life.

Job Applications

Earthwork and Rough Grading: Mount the HL760-NB on a grade rod to control cut and fill operations across large site preparation projects. The extended detection range keeps pace with heavy equipment moving across wide areas.

Pipe and Utility Installation: Use the receiver on a leveling rod inside the trench to dial in pipe slope quickly and accurately, reducing the need for repeated laser checks and string line setups.

Concrete Flatwork: Set screeds and forms to exact elevation by using the HL760-NB to verify grade at multiple points across the slab before and during pour, ensuring consistent floor flatness.

Multi-Crew Expansion: When one laser is serving two crews on opposite ends of a jobsite, a second HL760-NB receiver allows both teams to work simultaneously without sharing equipment or waiting on each other.

Frequently Asked Questions

Does the HL760-NB come with a rod clamp or mounting bracket?

No. The "NB" designation stands for "No Bracket." This version ships with the receiver unit only. If you need a rod clamp or machine mount, those are available separately. This configuration is ideal for contractors who already have compatible mounting hardware or who are purchasing a replacement receiver.

Which Spectra Precision lasers is the HL760-NB compatible with?

The HL760-NB is designed to work with Spectra Precision rotary lasers, including popular models like the GL412N, GL422N, LL300N, and similar single and dual-grade rotary laser levels. Check your laser model's documentation or contact our team to confirm compatibility with your specific unit.

What is the maximum detection range of the HL760-NB?

When paired with a compatible Spectra Precision rotary laser, the HL760-NB can detect the laser beam at ranges up to 2,000 feet in diameter. Actual range may vary based on atmospheric conditions, ambient light levels, and the output power of the laser being used.

Can the HL760-NB be used with machine control systems?

Yes. The HL760-NB can be mounted to a machine mast using a compatible Spectra Precision machine mount bracket (sold separately). It is commonly used with motor graders, dozers, and scrapers for automated grade control when integrated with the appropriate machine control system and compatible laser transmitter.
