Overview
The Spectra Precision LL300S-26 Laser Complete Package represents a professional-grade solution for contractors and site managers who demand accuracy without complexity. This self-leveling rotary laser system combines Spectra Precision's proven LL300S-26 laser transmitter with the rugged CR700 digital receiver, a 15-foot inches-graduated aluminum leveling rod, and a heavy-duty tripod—everything needed to establish precise elevation control straight out of the case.
Engineered for medium-range applications up to 1,000 feet diameter (500-foot radius), this laser package excels in site preparation, foundation work, concrete placement, and general grading operations. The LL300S-26 automatically levels itself within ±5 degrees and maintains accuracy to ±3/32 inch at 100 feet, ensuring reliable elevation references throughout the workday. Its dual-slope capability in both axes enables controlled drainage work and cross-slope grading, while the enclosed laser design withstands dust, rain, and the rigors of active construction sites.
What sets this complete package apart is the integration of the CR700 receiver—a backlit, dual-display detector that provides precision within 1/16 inch and works seamlessly with the LL300S-26's rotating beam. Whether you're shooting grade for building pads, setting footing elevations, or checking excavation depths, this system delivers consistent, repeatable results that keep projects on specification and on schedule.

Job Applications
- Site Grading and Excavation: Establish consistent grade elevations across large building pads and excavation areas. The 1,000-foot diameter range means fewer instrument setups, reducing setup time and increasing productivity on sprawling residential subdivisions or commercial developments.
- Foundation and Footing Work: Verify formwork elevation and ensure foundation systems are level before concrete placement. The ±3/32-inch accuracy maintains tight tolerances critical for structural integrity, while the CR700's audible alerts let crew members work hands-free without constantly checking the display.
- Concrete Slab Preparation: Set screeds and grade stakes for flatwork, basement floors, and parking structures. The dual-slope capability allows precise control for drainage-designed slabs, eliminating guesswork and costly rework when positive drainage is specified.
- Utility and Drainage Installation: Grade trenches for storm sewers, sanitary lines, and subsurface utilities requiring controlled slope. Manual slope adjustment in dual axes provides the flexibility needed for complex drainage networks and outfall systems.
- Landscape and Hardscape Grading: Control elevation for retaining walls, paver patios, walkways, and landscape features. The visible red beam works well in moderate lighting conditions, and the variable rotation speeds optimize visibility whether working in bright or lower-light environments.
- Interior Construction and Ceiling Grid: Set elevations for suspended ceiling systems, interior finish floors, and elevation-critical millwork. The compact laser head and tripod setup fits into tight interior spaces while maintaining the accuracy needed for architectural finishes.

FAQ
- What is the maximum distance I can use the CR700 receiver with this laser?
- The CR700 receiver works effectively with the LL300S-26 up to a 500-foot radius (1,000-foot diameter). Actual range depends on ambient lighting conditions, with optimal performance in overcast or indoor conditions. In bright sunlight, practical working range may reduce to 300-400 feet radius without laser enhancement glasses.
- Can I use this laser for drainage and slope work?
- Yes. The LL300S-26 features dual-axis manual slope capability, allowing you to set grades up to ±10% in both X and Y axes simultaneously. This makes it ideal for drainage applications, parking lot grading, and utility trenching where controlled slope is required. Slopes are set using the RC702 remote control included in the package.
- How long does the battery last on a single charge?
- The rechargeable NiMH battery provides approximately 60 hours of continuous operation under normal conditions. Battery life varies based on rotation speed (faster speeds consume more power) and temperature (cold weather reduces runtime). The package includes a charger, and spare batteries are available for extended workdays.
- Is this laser suitable for interior work like suspended ceilings?
- Absolutely. The LL300S-26 works exceptionally well for interior applications including ceiling grid installation, wall layout, and interior elevations. The visible red beam is easily detected indoors, and the compact size allows positioning in confined spaces. The included tripod provides stable elevation control for interior finish work.
