The Topcon RL-200 2S is a professional-grade dual slope rotary laser engineered for heavy civil grading, site development, and commercial excavation. This complete alkaline package includes the LS-100D digital receiver and a 16-foot elevator tripod with inch measurements, giving contractors a fully field-ready system straight out of the box. Whether you're cutting parking lots, establishing drainage grades, or pouring sloped concrete slabs, the RL-200 2S delivers repeatable, accurate elevation control across the entire jobsite.
Dual Slope Control for Complex Grading Operations
Unlike single-slope lasers, the RL-200 2S allows independent slope settings on both the X-axis and Y-axis simultaneously. This capability is essential for parking lot grading, athletic field construction, and any application requiring compound slopes. The laser self-levels within its compensator range and locks automatically, reducing setup time and operator error. The wide operating range and high RPM output ensure the LS-100D receiver picks up the beam reliably even on large, open sites.

Job Applications
Parking Lot Grading: Set independent X and Y slopes to achieve proper storm drainage grades across large paved surfaces without repositioning the instrument. The RL-200 2S holds grade reliably while machine operators work across the full site.
Site Excavation and Earthwork: Mount the laser on the elevator tripod at a safe perimeter location and use the LS-100D receiver on a grade rod to direct cut-and-fill operations. The 2,600-foot operating diameter covers most commercial excavation footprints.
Concrete Flatwork and Slabs-on-Grade: Establish precise screeding elevation or set form heights for sloped slabs. The LS-100D's audible and visual grade indication keeps finishers on grade without stopping work to check measurements.
Athletic Fields and Drainage Swales: Compound slope capability makes the RL-200 2S ideal for establishing precise crown and cross-slope on sports turf, ensuring proper surface drainage while meeting field specification tolerances.

Frequently Asked Questions
- Can the Topcon RL-200 2S set slope on both axes at the same time?
- Yes. The RL-200 2S is a true dual slope laser, meaning you can independently program X-axis and Y-axis grade simultaneously. This is the defining feature for compound grading tasks like parking lots and crowned fields where single-slope instruments fall short.
- Is the LS-100D receiver included, or does it need to be purchased separately?
- The LS-100D digital receiver is included in this package (SKU 314920782-2ET-ALKALINE). The kit also includes the 16-foot elevator tripod and alkaline batteries, so it is a complete, field-ready system requiring no additional purchases to begin work.
- What is the effective working range of the RL-200 2S?
- With the LS-100D receiver, the RL-200 2S has an operating diameter of up to 2,600 feet — over 1,300 feet in any direction from the instrument. This is sufficient for most commercial site grading, large parking lots, and multi-acre earthwork operations.
- Is the Topcon RL-200 2S weatherproof enough for outdoor jobsite use?
- Yes. The RL-200 2S carries an IP66 rating, meaning it is fully protected against dust ingress and resistant to high-pressure water jets. It is designed for outdoor use in rain, dust, and typical construction site conditions.
