The Topcon RL-200-2S-BL gives contractors a direct path to adding or replacing a dual slope rotary laser without repurchasing a full kit. Whether your original unit was damaged on the jobsite, lost, or you simply want to run a second laser off your existing receiver and rod eye setup, this bare laser delivers the same precision dual-axis grading performance as the full RL-200-2S package — just the laser transmitter, nothing else.
Overview: Where the RL-200-2S-BL Gets to Work
The RL-200-2S-BL is purpose-built for grade-critical applications where a single-axis laser falls short. Parking lot construction, athletic field grading, detention pond shaping, highway subgrade, and complex drainage systems all demand precise two-directional slope control — and that is exactly what this unit delivers. Topcon's proven self-leveling platform and robust housing make it equally at home on flat open sites and demanding civil grading operations.

Job Applications
Parking Lot Construction: Establish dual-direction cross-slope and longitudinal grade simultaneously across large paved areas, reducing the number of setups and keeping heavy equipment moving.
Athletic Field Grading: Crown and sideline fall grades require precise two-axis control. The RL-200-2S-BL holds both slopes independently so finish grading crews can work the full field without resetting the laser.
Detention Pond and Drainage Basin Shaping: Complex bottom grades and berm slopes on retention infrastructure demand dual-axis capability. Set invert and cross-slope simultaneously to hit design elevations on every pass.
Highway Subgrade and Shoulder Work: Control roadbed cross-slope and longitudinal grade in a single instrument setup, keeping motor graders and fine graders on grade across wide pavement sections.

Frequently Asked Questions
- What is included with the RL-200-2S-BL bare laser?
- The RL-200-2S-BL includes only the laser transmitter unit. No receiver, rod eye, remote control, tripod, carrying case, or accessories are included. This listing is designed for contractors who already own compatible Topcon receivers and accessories and need a replacement or additional laser only.
- Which receivers are compatible with the Topcon RL-200-2S-BL?
- The RL-200-2S-BL is compatible with Topcon laser receivers including the LS-100D and LS-80L. If you are unsure whether your existing receiver will work with this unit, contact our team and we will confirm compatibility before you order.
- Can I control slope settings remotely without walking back to the laser?
- Yes. The RL-200-2S-BL is compatible with the Topcon RC-400 remote control (sold separately), which allows you to adjust X and Y slope values wirelessly from the machine cab or from the grade rod position — a significant time saver on large grading sites.
- Is the RL-200-2S-BL covered under Topcon's warranty as an authorized dealer purchase?
- Yes. Express Tools is an authorized Topcon dealer, so the RL-200-2S-BL purchased through us qualifies for full Topcon manufacturer warranty coverage. Buying through an authorized dealer protects your warranty and ensures you receive a genuine Topcon product.
