Description

The Topcon RL-200 2S dual slope grade laser package gives civil contractors, site developers, and grading crews a complete, field-ready system engineered for precision dual-axis slope work. This kit pairs the industry-proven RL-200 2S rotating laser with the LS-80X machine-control-ready receiver, a tenths-graduated grade rod, and an elevator tripod — everything needed to establish accurate grade planes straight out of the case. Whether you're establishing swales, matching existing drainage slopes, or executing decimal-dimensioned site plans, this package delivers the accuracy and setup speed professional crews demand.

System Overview & Jobsite Applications

The RL-200 2S sets dual independent slopes simultaneously on the X and Y axes, making it uniquely suited for parking lots, athletic fields, drainage channels, and ADA-compliant flatwork where two-axis grade control is essential. The LS-80X digital receiver provides audible and visual grade indication with a 1/16-inch detection window for fine-grade work and interfaces with most machine control systems. The tenths-graduated rod simplifies reading decimal elevations directly from engineer's plans, eliminating conversion errors in the field.

Job Applications

Parking Lot & Hardscape Grading: Program independent X and Y slopes to direct stormwater to inlets without re-leveling the instrument. The 2,600-foot diameter working range covers large commercial lots in a single setup.

Athletic Fields & Sports Turf: Achieve consistent cross-slopes and crown grades on football fields, soccer pitches, and baseball infields — applications where both axes must slope simultaneously and uniformly.

Drainage Channels & Swales: Set longitudinal and cross-slope in a single instrument position. The tenths rod lets crews read engineer-plan elevations directly without converting fractions.

Machine Control & Grade Checking: The LS-80X receiver mounts to motor graders, scrapers, and excavators for automated blade control, then doubles as a handheld checker for final grade verification.

Frequently Asked Questions

Can the RL-200 2S set different slopes on both axes at the same time?: Yes. The RL-200 2S is a true dual-slope instrument, allowing you to independently program a slope value on the X-axis and a separate slope value on the Y-axis simultaneously — no need to re-level or reposition the instrument between axis adjustments.
Why does this kit include a tenths rod instead of a standard 8ths rod?: Civil engineering and site development plans are typically drawn in decimal feet. A tenths-graduated rod lets your crew read 0.1-foot increments directly from the rod face, matching your plan dimensions exactly and eliminating the math errors that come with converting fractions to decimals in the field.
What is the advantage of an elevator tripod in a laser kit?: An elevator tripod has a center column that raises and lowers independently of the tripod legs. This lets you quickly adjust instrument height to clear obstacles, match a required benchmark elevation, or reposition for different crew needs without having to re-level the tripod from scratch each time.
Is the LS-80X receiver included in this package compatible with excavator or motor grader machine control systems?: The LS-80X is designed with machine control compatibility in mind and can interface with most popular aftermarket and OEM grade control systems via its mast-mount bracket. Always verify pin-out and signal compatibility with your specific machine control brand before installation.
