Spectra Precision LL300S-16 PRO Laser Complete Package w/ CR700 Receiver, 10ths Rod and Tripod

The Spectra Precision LL300S-16 PRO is a professional-grade self-leveling rotary laser level kit built for contractors who need dependable elevation control across grading, drainage, foundation, and site work applications. Packaged as a complete field-ready system, the LL300S-16 PRO includes the CR700 multi-mode laser receiver, a 15-foot tenths rod, a heavy-duty tripod, and batteries — so your crew hits the ground running without waiting on secondary orders or missing components.

Product Overview

Designed for mid-range jobsite accuracy and built to Spectra Precision's proven durability standards, the LL300S delivers consistent horizontal plane coverage up to 800 feet in diameter with the included CR700 receiver. Whether you're shooting grades for a parking lot, setting drainage slopes, or verifying foundation elevations, the LL300S-16 PRO provides the performance and reliability that keeps your project on schedule. The self-leveling mechanism activates within ±5° of level and locks the beam automatically, reducing setup time and operator error on uneven terrain.

Job Applications

Site Grading & Earthwork: Set consistent cut-and-fill grades across large disturbed areas. The 800-foot working diameter means fewer instrument moves per site, keeping your operators productive and reducing overall grading time.

Drainage & Slope Control: The single-axis grade function lets you dial in specific slope percentages for swales, detention basins, and pipe trenches without secondary calculations or string lines — improving accuracy and eliminating rework.

Foundation Layout & Elevation Checks: Verify form elevations and slab benchmarks with ±1/16-inch accuracy at 100 feet. The CR700 receiver's light-bar readout gives rod operators instant above/below/on-grade confirmation without radio communication delays.

Agricultural & Landscape Leveling: The IP66 rating and -4°F low-end operating temperature make the LL300S-16 a reliable choice for field leveling, irrigation grading, and landscape contouring in variable outdoor conditions throughout the work year.

Frequently Asked Questions

Does the LL300S-16 PRO work in outdoor daylight conditions?

Yes. The included CR700 receiver is required for outdoor use in ambient light. The CR700 detects the rotating laser beam even in full sun, providing directional feedback via its light-bar display at distances up to 800 feet. The laser is not visible to the naked eye at typical working distances in daylight.

Can the LL300S-16 shoot grades, or is it horizontal-only?

The LL300S-16 includes single-axis grade capability, allowing operators to dial in slopes from 0 to 25% on one axis. This makes it suitable for drainage grading, pipe trenching, and sloped slab work without the need for a full dual-axis grade laser.

What is the difference between the LL300S-16 and the LL300N?

The LL300S adds single-axis grade matching capability and is packaged as a more complete PRO kit. The LL300N is a horizontal-only self-leveling laser better suited for interior or flat-grade applications. If your work involves drainage or slope control, the LL300S-16 PRO is the appropriate choice.

Is the LL300S-16 PRO covered under warranty?

Yes. Spectra Precision backs the LL300S-16 with a standard manufacturer's warranty.
