Ready-to-Work Rotary Laser Package for Concrete and Site Prep Professionals
The Spectra Precision LL1505C-19S is a complete, job-site-ready rotary laser package built for contractors who need to hit the ground running. This factory-configured kit pairs the rugged LL1505C self-leveling rotary laser with the Spectra HL760 digital receiver, a tenths-graduated grade rod, a heavy-duty aluminum tripod, and a protective carrying case — everything needed to start laying accurate grades from the moment you arrive on site. Whether you're placing concrete flatwork, cutting subgrade, or checking drainage slopes, this package removes the guesswork from equipment selection and delivers a proven, integrated setup trusted on thousands of job sites.
Product Overview & Jobsite Applications
The LL1505C operates at up to 1,200 RPM with a working range of 2,000 feet in diameter when paired with the HL760 receiver. Its self-leveling pendulum compensator automatically plumbs the beam within ±5 arc minutes, and the instrument shuts down safely if knocked out of level — protecting both the tool and your layout data. The HL760 receiver features a large, easy-to-read display with directional arrows and numeric elevation offset readout, making grade checks fast even when the instrument is 800 feet away. Built to IP66 standards, both units are rated for rain, mud, and the kind of abuse a busy site crew delivers daily.

Job Applications
Concrete Flatwork & Slab-on-Grade: Set your instrument elevation once and let form setters work independently across the slab area using the HL760 receiver. The 1,200 RPM rotation speed keeps the beam cycling fast enough that crews rarely wait for a reading.
Site Grading & Cut/Fill Operations: The 2,000-foot working diameter covers most residential and light commercial grading spreads. Grade the receiver rod directly on the blade of a skid steer or laser screed for machine-control-style accuracy without the machine-control price tag.
Foundation & Footing Layout: Use the tripod-mounted LL1505C as a benchmark reference throughout the foundation pour sequence. Consistent benchmark elevation means fewer re-checks and faster form stripping.
Drainage & Utility Slope Work: The LL1505C supports single-axis grade mode, making it suitable for setting consistent pipe-trench inverts and drainage swale profiles when paired with a grade rod and experienced rod person.

Frequently Asked Questions
- Does the LL1505C-19S package work for single-axis grade applications?
- The LL1505C supports a manual grade mode on one axis, but it is primarily designed as a horizontal leveling laser. For dedicated dual-axis grade work, consider upgrading to a Spectra GL series grade laser. For flat layouts, drainage slopes, and basic site grading, most contractors find the LL1505C fully adequate.
- What is the maximum working range of this package?
- When used with the included HL760 receiver, the LL1505C delivers a usable working radius of up to 1,000 feet (2,000 feet in diameter) under normal outdoor conditions. Bright sunlight can reduce visible beam detection, which is why the HL760 receiver is essential for outdoor work beyond 50 feet.
- Is the HL760 receiver compatible with other Spectra or Trimble lasers?
- Yes. The HL760 is compatible with most Spectra Precision and Trimble rotating lasers that emit a standard 635–690nm red laser beam. It will also work with many competing brands of rotary lasers operating at the same wavelength, making it a versatile addition to any survey or layout equipment inventory.
- What warranty comes with the LL1505C-19S package?
- Spectra Precision backs the LL1505C with a 3-year instrument warranty and a 1-year warranty on accessories including the HL760 receiver, grade rod, and tripod. Express Tools is an authorized Spectra Precision dealer, so all warranty service is fully supported through official channels.
