Professional Dual-Axis Grading Laser for Complex Site Work
The Topcon RL-200 2S is a self-leveling, dual-slope rotating laser built for contractors who need precise X and Y axis grade control on demanding jobsites. Model 314920782-2T is the complete 2T package — everything you need straight out of the box. With a maximum slope capability of 25% on both axes simultaneously, the RL-200 2S tackles complex grading tasks that a single-axis laser simply can't handle. Whether you're cutting slopes on a commercial parking lot, establishing finish grades for a sports field, or controlling drainage on a large pad, this machine delivers the accuracy and reliability Topcon is known for.
Package Overview & Jobsite Applications
The RL-200 2S 2T package is designed to be a complete, field-ready solution. It ships with the LS-100D digital receiver, which provides clear cut/fill audio and visual feedback at extended ranges. The included RD-400 remote control lets operators adjust grade settings from across the jobsite without returning to the instrument — a real time-saver when you're dialing in finish grades. The rechargeable Li-ion battery system delivers consistent runtime throughout a full workday, and the heavy-duty tripod and grade rod round out the kit for immediate deployment on any site.

Job Applications
Commercial Parking Lots: Establish dual-direction cross slopes to meet ADA drainage requirements and spec tolerances — simultaneously control X and Y pitch without resetting the instrument.
Athletic Fields & Turf Grading: Crown grading for football fields, soccer pitches, and baseball infields requires consistent fall in two directions. The RL-200 2S sets both grades in one shot.
Site Pads & Building Foundations: Control finish subgrade elevation and slope simultaneously to ensure proper drainage away from structures across large building pads.
Road & Highway Shoulder Work: Set and maintain consistent cross-fall on road shoulders and ditches where both longitudinal and transverse grades must be held tight.

Frequently Asked Questions
- Can the RL-200 2S set different slopes on both axes at the same time?
- Yes — that's the core capability of the RL-200 2S. You can independently dial in X-axis and Y-axis grades up to 25% simultaneously, making it ideal for any application requiring compound slope control.
- What is the working range of the included LS-100D receiver?
- The LS-100D receiver is rated for use up to 800 meters (approximately 2,600 feet) from the laser head in good conditions, providing ample coverage for large commercial sites.
- Is the RL-200 2S compatible with machine control systems?
- The RL-200 2S is primarily a manual-control grade laser designed for rod-and-receiver grade checking. For full machine control integration (motor graders, dozers), Topcon's GL or RL-SV series are the recommended platforms.
- How long does the battery last on a full charge?
- Topcon rates the Li-ion battery system at approximately 60 hours of continuous operation. Most contractors get a full week of typical site use on a single charge cycle.
