Spectra Precision LL1505C-26A Laser Level Package with CR700 Multi-Use Receiver, Rod INCHES, Tripod and Large SYSTEM Case

The Spectra Precision LL1505C-26A is a complete, jobsite-ready rotary laser package built for contractors who need reliable accuracy across grading, excavation, concrete placement, and general site layout. Everything you need arrives in one system case: the LL1505C self-leveling rotary laser, the CR700 multi-use receiver, a soft-app remote control, an aluminum tripod, a grade rod graduated in inches, and a protective system case. No hunting for accessories — unbox it and get to work.

Rotary Laser Overview & Jobsite Applications

The LL1505C uses motorized self-leveling technology to automatically compensate for minor setup variations, getting you on grade faster than manual instruments. With a working range of up to 2,000 feet in diameter (with receiver), this laser handles large open sites without repositioning. The CR700 receiver provides clear, audible and visual grade indication so operators can work efficiently even in bright daylight. A remote control lets the grade foreman adjust the laser from the rod location — no trips back to the instrument.

Job Applications

Grading & Earthwork: Establish consistent grade elevations across large cuts and fills. The 2,000 ft range covers most residential and light commercial site work without moving the instrument.

Concrete Flatwork & Foundations: Set screed rails, check form elevations, and verify slab thickness with repeatable accuracy. The ±1/16 in. at 100 ft spec meets typical ACI flatness tolerances.

Excavation & Utility Trenching: Keep trench bottoms on slope and verify subgrade before stone placement. The CR700 receiver's rod holder clamps to standard grade rods for hands-free reading.

Landscape & Drainage: Set swales, retaining wall footings, and drainage outlets to positive grade. The remote control keeps one operator running both the rod and the laser adjustment.

Frequently Asked Questions

Does the LL1505C-26A shoot grade (slope)?

The LL1505C supports manual grade via its tilting base, allowing the user to set single-axis slopes for drainage and road crown applications. It is not a dual-axis automatic grade laser, so slopes are set manually by tilting the instrument on its base rather than dialing in a percentage electronically.

What is the maximum range of the LL1505C with the CR700 receiver?

With the included CR700 receiver, the working diameter reaches up to 2,000 feet — a 1,000-foot radius from the instrument. In direct sunlight the receiver's detection window helps maintain reliable signal at extended distances where the naked eye cannot see the beam.

Is the Spectra Precision LL1505C weatherproof?

Yes. The LL1505C carries an IP66 rating, meaning it is fully protected against dust ingress and can withstand powerful water jets. It is designed for active outdoor jobsite use in rain and dusty conditions, though it should not be submerged.

What batteries does the LL1505C use and how long do they last?

The LL1505C runs on standard alkaline D-cell batteries and delivers up to 100 hours of runtime per set under normal operating conditions. Alkaline batteries are widely available at supply houses and hardware stores, reducing downtime on the job.
