The Topcon RL-200 2S (Model 314920782) is a professional-grade dual slope rotating laser system engineered for survey crews and excavation contractors who demand precise independent X/Y axis grade control, long-range detection, and the convenience of wireless remote operation. Sold as a complete package through Express Tools, this kit includes the LS-100D digital receiver, the RD-400 wireless remote control, and a rechargeable battery kit—giving your crew everything needed to start grading accurately from day one without the recurring cost of disposable batteries.
System Overview & Jobsite Applications
Built around Topcon's proven dual-grade platform, the RL-200 2S allows operators to independently set slope on both the X and Y axes simultaneously—critical for drainage swales, parking lot crowns, roadway cross-slopes, and agricultural land leveling. The laser broadcasts a visible red beam across a full 360-degree sweep, and the included LS-100D receiver extends working range to 2,600 feet in diameter (1,300 ft radius), making it one of the most capable systems in its class for large open-site applications. When instrument repositioning is needed, the RD-400 remote lets a single operator adjust slope settings, self-leveling, and power from up to 330 feet away—eliminating time lost walking back to the instrument.

Job Applications
Parking Lot & Flatwork Grading: Set independent X and Y slopes for proper stormwater drainage across large paved surfaces. The RL-200 2S holds grade accurately over long distances without operator intervention.
Drainage Swales & Detention Basin Slopes: Dial in precise fall rates on both axes simultaneously to meet civil engineering grade requirements on swales, retention pond berms, and detention basins.
Roadway Cross-Slope & Subgrade: Establish consistent cross-falls on roadbed subgrades for DOT-compliant base prep. Remote control capability lets the machine operator verify and adjust grade without leaving the cab area.
Agricultural Land Leveling: The 25% maximum slope range covers steep terrain demands in agricultural grading and field leveling applications where single-axis instruments fall short.

Frequently Asked Questions
- Can the RL-200 2S set different slopes on both axes at the same time?
- Yes. The RL-200 2S is specifically designed for simultaneous dual-axis slope control. You can independently program the X-axis and Y-axis grades up to ±25% each, making it ideal for crowned surfaces, cross-slopes, and complex drainage layouts that a single-slope laser cannot handle.
- What is the working range of the included LS-100D receiver?
- The LS-100D digital receiver extends the effective working diameter to approximately 2,600 feet (1,300-foot radius) under good conditions. This makes the RL-200 2S suitable for large open jobsites such as parking lots, airfields, and agricultural fields where long-range accuracy is critical.
- How far away can I operate the laser with the RD-400 remote?
- The RD-400 wireless remote provides control of the RL-200 2S from up to 330 feet away. Functions controllable via remote include power on/off, slope adjustments on both axes, and self-leveling activation—allowing a single operator to manage the instrument from a machine or rod location without returning to the tripod.
- Does this package include rechargeable batteries, or do I need to purchase them separately?
- This complete package (Model 314920782) includes the rechargeable Ni-MH battery pack and charger. The battery provides over 35 hours of continuous runtime, eliminating the need for disposable batteries and reducing long-term operating costs significantly for crews using the instrument daily.
