Overview
The Topcon RL-200 1S Single Slope Grade Laser Package represents the professional contractor's choice for precision grading work across excavation, drainage, and foundation applications. This complete system pairs Topcon's rugged RL-200 1S rotating laser with the advanced LS-100D digital receiver and rechargeable battery configuration, eliminating the recurring cost and inconvenience of disposable batteries while delivering exceptional uptime on extended job sites.
Built for contractors who demand reliable elevation control day after day, this package combines single-axis slope capability with Topcon's renowned durability and ease of use. The RL-200 1S automatically levels and maintains grade across distances up to 2,600 feet diameter (800m), while the LS-100D receiver provides enhanced sensitivity and precision detection even in challenging lighting conditions. The rechargeable battery system ensures you're always ready for full-day operation without battery runs to the supplier.
Whether you're establishing drainage grades, setting foundation elevations, or controlling excavation depth, this turnkey system delivers survey-grade accuracy in a package designed for the rigors of active construction sites. The intuitive controls and automatic leveling mean less setup time and more productive hours, while the IP66 environmental rating ensures performance in dust, rain, and demanding field conditions.

Job Applications
- Site Excavation and Grading: Establish consistent depth control across large excavation areas, ensuring proper subgrade preparation while minimizing over-excavation costs. The single slope capability allows you to set drainage pitches without complex calculations or multiple setups.
- Foundation and Flatwork: Create level references for concrete pours, slab preparation, and foundation layouts with survey-grade precision. The 360-degree laser plane eliminates the need for string lines and provides instant elevation checks at any point around the job site.
- Drainage and Utility Trenching: Set precise slopes for sewer lines, stormwater systems, and utility installations. The single-axis slope function maintains consistent grade over extended runs, ensuring proper flow without standing water or excessive velocity issues.
- Agricultural Land Leveling: Control elevation across fields for irrigation efficiency and water management. The extended 2,600-foot working diameter covers large areas from a single setup, reducing positioning time and increasing productivity on acreage projects.
- Parking Lot and Roadway Subgrade: Establish base grades for asphalt and concrete paving projects, ensuring proper drainage and structural depth. The rechargeable battery system supports all-day operation without interruption, critical for time-sensitive grading operations.
- Retaining Wall and Landscaping: Set consistent elevations for tiered landscapes, retaining wall footings, and decorative hardscape installations where precise grade control enhances both function and appearance.

FAQ
- How long does the rechargeable battery last on a typical job?
- The included Ni-MH rechargeable battery pack provides up to 100 hours of continuous operation for the RL-200 1S laser unit under normal conditions. The LS-100D receiver operates for approximately 60-80 hours on its batteries. In practice, this means several full days of work between charges for most contractors. The package includes a charger, and we recommend keeping a spare battery pack on hand for back-to-back long days or when charging isn't convenient.
- What's the difference between the LS-100D receiver and standard receivers?
- The LS-100D offers enhanced receiver sensitivity and digital accuracy compared to basic receivers, extending the effective working range and providing more precise detection in bright sunlight or at longer distances. It features a larger LCD display with visual and audible grade indicators, making it easier to achieve exact elevation quickly. The improved electronics also provide better battery life and more consistent performance across the full detection range.
- Can this laser be used for interior concrete floor leveling?
- Absolutely. The RL-200 1S excels at interior flatwork, providing a consistent level reference across the entire floor area. The 360-degree rotating beam allows multiple workers to check elevation simultaneously from different positions. For large commercial floors or warehouses, the 2,600-foot diameter coverage means fewer laser repositions. The system is equally effective for screeding concrete, setting forms, or checking finished floor flatness.
- Is the single slope function difficult to set up for drainage work?
- No—Topcon designed the slope adjustment to be contractor-friendly. The RL-200 1S features manual slope controls with clear indicators, allowing you to set grade in one direction. For common drainage applications (typically 1-2% slope), you simply adjust the slope knob to the desired percentage, and the laser maintains that plane. The included manual provides a quick reference chart for common slope percentages, and most operators become proficient within minutes of first use.
