Complete Professional Laser System — Ready to Work From the First Setup
The Spectra Precision LL1505C-27 is a fully matched laser package built for contractors who need reliable horizontal leveling without the hassle of sourcing components separately. Every piece in this kit is selected to work together — the LL1505C rotary laser, the HL760 long-range receiver, an inch-graduated aluminum grade rod, a heavy-duty tripod, and a large hard-shell system case. Unbox it on the jobsite and you're ready to shoot grades, set forms, and verify elevations the same day it arrives.
Overview & Jobsite Applications
The LL1505C is a self-leveling horizontal rotary laser designed for outdoor construction work where accuracy and range matter. It self-levels within ±5 degrees, spins a visible red beam in a full 360-degree plane, and works reliably in direct sunlight when paired with the included HL760 detector. Whether you're grading a pad, setting drainage slope, or transferring elevations across a large site, this system delivers the precision and range professional crews expect.

Job Applications
Site Grading & Earthwork: Set the LL1505C on a tripod at a central benchmark and use the HL760 receiver on your grade rod to verify cut-and-fill elevations across the entire pad. The 2,000-foot working diameter means you're not constantly repositioning the instrument on large commercial sites.
Concrete Form Setting: Transfer a level reference across footing forms, slab perimeters, and stem walls with consistent accuracy. The selectable rotation speeds let you slow the beam for easier manual reads or speed it up for detector-only work.
Drainage & Pipe Installation: Establish consistent grade references for storm drain, sanitary sewer, and utility trench work. The inch-graduated rod in this package is calibrated for traditional imperial readings familiar to most field crews.
Foundation & Floor Elevation Checks: Use the system to verify as-built elevations against design drawings, check floor flatness on concrete pours, and confirm benchmark elevations before structural work begins.

Frequently Asked Questions
- Does the LL1505C-27 work in direct sunlight?
- Yes. The LL1505C emits a red beam that is difficult to see with the naked eye outdoors in bright conditions, but the included HL760 receiver detects the beam accurately in full sunlight at ranges up to 2,600 feet. For visible indoor work, the laser is clearly usable without the detector.
- Is this package metric or imperial?
- The LL1505C-27 includes an inch-graduated aluminum grade rod, making it configured for traditional imperial measurement common on U.S. job sites. If your crew works in metric, Express Tools also carries metric rod configurations compatible with the same LL1505C laser unit.
- What is the self-leveling range of the LL1505C?
- The LL1505C will self-level automatically when the instrument is set up within ±5 degrees of level. If the unit is tilted beyond that range, it will alert the user and stop rotating until it is properly leveled. This protects against false grade readings caused by an out-of-level setup.
- Can I use the HL760 receiver with other Spectra Precision lasers?
- The HL760 is a universal-style receiver compatible with most Spectra Precision and Trimble red-beam rotary lasers. It is not limited to the LL1505C, making it a useful standalone accessory if you later add additional laser instruments to your kit.
