The Topcon RL-200 2S Dual Slope Grade Laser (314920712-BCA) delivers the precision two-axis slope control that serious grading contractors demand. Whether you're laying out a commercial parking lot, establishing drainage fall on an agricultural field, or setting complex sub-grade for a building pad, the RL-200 2S lets you dial in independent X and Y slopes simultaneously—eliminating the guesswork and saving hours of grade-checking time. This BCA package includes the laser unit, Topcon's rechargeable battery system, and a rugged protective carrying case. A compatible receiver is sold separately, giving you the flexibility to match the detector to your specific application.
Overview & Jobsite Applications
The RL-200 2S is engineered for contractors who regularly tackle grading work that goes beyond simple single-plane applications. Its dual-slope functionality means you can set a cross-slope and a longitudinal slope at the same time, replicating real-world site conditions where water must sheet off in two directions. The laser broadcasts a 360-degree rotating beam with a working radius suited to large open jobsites, and its robust self-leveling system keeps the plane accurate even as conditions change through the workday. From concrete flatwork to earthwork and irrigation grading, the RL-200 2S is built to perform in demanding outdoor environments.

Job Applications
Parking Lots & Paved Surfaces: Set cross-slope and longitudinal grade simultaneously to ensure proper stormwater runoff across the entire paved surface. The RL-200 2S eliminates the need for multiple setups and reduces grade-stake labor significantly.
Building Pads & Slab Prep: Establish a perfectly graded sub-base with controlled slope in both axes before pouring concrete. Consistent grade translates directly to reduced material waste and fewer finishing corrections.
Drainage & Irrigation Channels: Agricultural and site-utility contractors use the dual-slope capability to grade drainage swales and irrigation channels that must maintain precise fall in two directions across wide open terrain.
Highway & Road Construction: Set superelevation and longitudinal grade simultaneously for road base work, shoulder grading, and ditch profiles—keeping the machine operator on grade without constant manual checks.

Frequently Asked Questions
- Does this package include a laser receiver?
- No. The 314920712-BCA kit includes the RL-200 2S laser, rechargeable battery pack, charger, and carrying case. A compatible receiver such as the Topcon LS-100D or RD-1NX must be purchased separately depending on your application.
- What is the maximum slope range the RL-200 2S can handle?
- The RL-200 2S supports up to ±10% grade on both the X and Y axes independently, making it suitable for the vast majority of commercial and civil grading applications including parking lots, athletic fields, and drainage systems.
- Can the RL-200 2S be used with a machine control system?
- Yes. When paired with a compatible Topcon machine control receiver such as the LS-100D, the RL-200 2S integrates into blade and bucket control systems for motor graders, dozers, and scrapers, improving grade efficiency and cut/fill accuracy.
- Is the Topcon RL-200 2S suitable for use in rain or dusty conditions?
- Yes. The RL-200 2S carries an IP66 rating, meaning it is fully protected against dust ingress and resistant to heavy water jets. It is designed for all-day use in typical outdoor construction environments.
