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.
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 such as parking lots, athletic fields, and drainage pads.
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 under good atmospheric conditions, providing ample coverage for large commercial and civil grading sites.
Is the RL-200 2S compatible with machine control systems?
The RL-200 2S is primarily designed for manual grade checking with a rod and receiver. For full automated machine control integration on motor graders or dozers, Topcon recommends the GL series or RL-SV2S laser platforms instead.
How long does the battery last on a full charge?
Topcon rates the included Li-ion rechargeable battery system at approximately 60 hours of continuous runtime. Under typical field use, most contractors can run the RL-200 2S for a full week without needing to recharge.
