Professional Rotary Laser Package for Site Work, Foundations & Excavation
The Spectra Precision LL1505C-18S is a fully equipped rotary laser package designed for contractors who depend on accurate, repeatable leveling across demanding jobsite conditions. Whether you're setting concrete forms, grading a pad, or establishing benchmarks across an excavation site, this package ships with everything you need to get on grade fast — the LL1505C self-leveling laser, CR700 multi-use receiver, tenths-graduated grade rod, heavy-duty aluminum tripod, and a protective carrying case. No hunting for accessories, no separate orders. One package, ready to work.
Laser Overview & Jobsite Applications
The LL1505C operates as a single-speed, self-leveling rotary laser with an automatic compensation range that handles minor tripod settling and soft ground without requiring a manual reset. It's engineered for outdoor use with a working range of up to 2,000 feet in diameter when paired with the included CR700 receiver, making it well-suited for large site layouts, road grading, utility trenching, and slab-on-grade work. The laser produces a highly visible reference plane that contractors can shoot to quickly with the CR700 detector even in direct sunlight conditions.

Job Applications
Concrete Flatwork & Slab Pours: Shoot grade across screeds and form work to maintain consistent slab thickness and meet spec tolerances on commercial and residential pours.
Site Grading & Earthwork: Establish a laser reference plane across the full site to control cut and fill operations, keeping equipment operators on grade without constant re-checking.
Foundation Layout & Elevation Transfer: Transfer benchmark elevations around a foundation perimeter accurately using the tenths rod and CR700 receiver for fast, consistent readings.
Utility Trenching & Pipe Grade: Set pipe slope and confirm trench bottom elevation on storm, sewer, and water main installations where grade tolerances are critical.

Frequently Asked Questions
- Does the LL1505C-18S package include everything I need to start using it on the jobsite?
- Yes. The 18S package includes the LL1505C laser, CR700 receiver, 18-foot tenths-graduated grade rod, aluminum tripod, battery pack, charger, and carrying case. You can unbox it and be on grade the same day it arrives.
- What is the working range of the LL1505C with the CR700 receiver?
- With the included CR700 receiver, the LL1505C has an effective working range of up to 1,000 feet in radius — or 2,000 feet diameter — making it more than adequate for most residential and light commercial site work.
- Is the LL1505C weatherproof enough for outdoor use?
- The LL1505C carries an IP54 rating, which means it is protected against dust ingress and water splashing from any direction. It can handle typical outdoor jobsite conditions including light rain. It should not be submerged or exposed to direct heavy rainfall for extended periods.
- Can the LL1505C be used for slope or grade applications?
- The LL1505C is a single-plane self-leveling laser optimized for level reference work. It does not have a manual slope or grade-setting function. For controlled slope applications, consider the Spectra LL500 series or a grade laser with dual-axis manual slope capability.
