Overview
The Topcon RL-200 2S Dual Slope Grade Laser Package (Model 314920722) delivers professional-grade precision for contractors tackling complex grading projects that demand accurate dual slope control. This horizontal-only rotating laser system combines Topcon's legendary reliability with advanced dual slope functionality, making it the ideal choice for drainage installations, parking lot grading, athletic fields, and large-scale foundation work. The complete package includes the RL-200 2S laser, LS-80L wireless receiver with rod clamp, rechargeable battery system, and rugged carrying case—everything you need to achieve ±1/8-inch accuracy at 100 feet right out of the box.
Unlike single-slope lasers that limit you to simple grade applications, the RL-200 2S enables independent slope control on both the X and Y axes simultaneously. This dual slope capability means you can establish proper drainage across multiple planes without repositioning equipment, dramatically reducing setup time on large sites. The intuitive control panel features dedicated slope controls for each axis, while the bright LED display ensures visibility even in direct sunlight. Built to withstand the rigors of daily construction use, the RL-200 2S features IP66 water and dust resistance, protecting your investment against rain, concrete dust, and job site debris.
The included LS-80L wireless receiver extends your working range to an impressive 2,600-foot diameter (1,300-foot radius), giving you coverage for even the largest commercial projects. The receiver's wireless remote operation eliminates the need to walk back to the laser head for adjustments, keeping your workflow efficient when you're working solo or coordinating with equipment operators. With accuracy that holds ±3/32 inch at 100 feet and construction-grade durability, this package represents exceptional value at $2,995 for contractors who demand professional performance without the premium price tag of full robotic systems.

Job Applications
- Drainage and Storm Water Systems: Dual slope capability allows you to establish proper pitch in multiple directions simultaneously, essential for swales, catch basins, and subsurface drainage that requires water flow toward collection points from multiple angles.
- Parking Lot and Roadway Grading: Create complex crowned surfaces and multi-plane drainage patterns that direct water away from structures and toward drains. The ability to set independent X and Y slopes eliminates the need for multiple laser setups, cutting your grading time significantly on large paving projects.
- Athletic Fields and Recreation Areas: Achieve the precise multi-directional slopes required for proper field drainage on baseball diamonds, football fields, and soccer pitches. The RL-200 2S helps you create the subtle grades that prevent standing water while maintaining playability standards.
- Large Foundation Excavations: Establish accurate benchmarks across expansive foundation digs where simple single-plane grading isn't sufficient. The 2,600-foot working diameter covers even the largest commercial foundation footprints without repositioning, while dual slope control accommodates sites with complex drainage requirements.
- Site Development and Mass Grading: Control elevation across large development sites where terrain naturally slopes in multiple directions. The wireless receiver lets equipment operators make real-time adjustments from the cab, increasing productivity on dozer and scraper operations while maintaining grade accuracy.
- Concrete Slab Preparation: Set the precise grades needed for large warehouse floors, manufacturing facilities, and commercial slabs where drainage or operational requirements demand sloped surfaces. The long runtime (100 hours) means the laser keeps working through extended concrete pours without battery changes.

FAQ
- What's the difference between single slope and dual slope lasers?
- Single slope lasers can only create a grade on one axis at a time (either X or Y direction), meaning they're limited to simple pitched surfaces like basic foundation footings or single-direction drainage. Dual slope lasers like the RL-200 2S can establish independent slopes on both X and Y axes simultaneously, creating complex multi-directional grades essential for parking lots, athletic fields, and advanced drainage systems. This eliminates the need to reposition your laser multiple times when establishing crowned or compound-sloped surfaces.
- How far can I work from the laser with the LS-80L receiver?
- The LS-80L receiver provides a working diameter of 2,600 feet (1,300-foot radius from the laser head) under optimal conditions. Actual range may be affected by bright sunlight, airborne dust, or atmospheric conditions. For most construction applications, you'll achieve reliable detection at 800-1,000 feet in typical job site conditions, which covers the vast majority of commercial grading projects without repositioning equipment.
- Can I use this laser for vertical layout or plumb applications?
- No, the RL-200 2S is a horizontal-only rotating laser designed exclusively for grade work and elevation control. It cannot be tilted to vertical orientation for plumb bob applications, wall layout, or structural alignment. If you need both horizontal grading and vertical plumb capability, consider a dual-grade laser model like the Topcon RL-H5A or a dedicated rotary laser with axis lock features that allow 90-degree positioning.
- How long does the battery last and how do I know when it needs charging?
- The included rechargeable Ni-MH battery provides up to 100 hours of continuous operation on a full charge under normal temperature conditions. The laser's control panel features a battery status indicator that alerts you when power is running low, typically giving you several hours of warning before shutdown. Cold weather can reduce runtime, so we recommend keeping a fully charged spare battery for winter work or starting each week with a fresh charge for critical projects where downtime isn't acceptable.
