Overview
The Topcon LS-B110W PRO Wireless Laser Receiver System (312670121) revolutionizes grade control for excavation and grading professionals by eliminating the limitations of wired connections. This complete PRO-WIRELESS package combines Topcon's rugged LS-B110W laser receiver with the innovative RD-100W Remote Display featuring built-in magnetic mounts, delivering real-time elevation data exactly where you need it—whether mounted in the cab, on the blade, or held at ground level for manual checks.
Designed for contractors who demand accuracy without sacrificing mobility, this system wirelessly transmits precise laser detection data up to 150 feet from sensor to display. The LS-B110W captures rotating laser signals across a generous detection window, while the RD-100W presents cut/fill information through an intuitive visual interface with audio alerts. The magnetic mounting system allows operators to reposition the display instantly without tools, making it perfect for equipment that requires frequent visibility adjustments or multi-operator environments.
Built to withstand the punishing conditions of construction sites, both components feature IP67-rated weatherproof housings that shrug off mud, rain, and impact. Long battery life ensures all-day operation, while the wireless connection remains stable even through vibration and electromagnetic interference common around heavy machinery. For contractors running multiple machines or frequently moving between equipment, this system dramatically reduces setup time while maintaining the measurement precision Topcon is known for.

Job Applications
- Excavator Grade Control: Mount the LS-B110W on the excavator boom or stick while keeping the RD-100W display inside the cab on the window or console. The wireless connection eliminates cables that snag, break, or interfere with machine movement, while operators maintain constant visual feedback on depth without leaning out or repositioning.
- Dozer and Motor Grader Operations: Position the sensor on the blade for accurate cut/fill readings while the magnetic display attaches instantly to any metal cab surface. Operators can adjust display placement based on sun angle or personal preference throughout the day, maximizing visibility in changing conditions without stopping work.
- Skid Steer and Compact Equipment: The system's compact footprint and wireless design make it ideal for smaller machines where space is limited and cable routing is problematic. The magnetic display moves effortlessly between equipment, making it perfect for contractors who need one system to serve multiple machines on site.
- Utility Trenching: Ground crews can hold the RD-100W display for manual grade checks while the receiver remains mounted on the trencher or excavator bucket. This eliminates the need for separate grade rods and constant remeasurement, dramatically speeding up utility installation while ensuring proper slope.
- Foundation and Pad Preparation: Operators can perform rough grading from the cab, then grab the magnetic display for final hand-finishing walks around the perimeter. The wireless range allows checking grades across large pads without moving the equipment or losing laser connection, reducing fuel consumption and compaction issues.
- Multi-Machine Job Sites: Supervisors and foremen can monitor grade progress by walking between machines with the RD-100W display, connecting to different LS-B110W receivers across the site. This provides real-time quality control without interrupting operators or waiting for traditional survey checks.

FAQ
- Can I use multiple RD-100W displays with a single LS-B110W receiver?
- Yes, the LS-B110W can pair with multiple RD-100W displays simultaneously, allowing both the operator in the cab and a ground crew member to view real-time grade information from the same sensor. This is particularly valuable for training situations or when fine-grading requires coordination between machine and manual work.
- How does the wireless system perform around other radio equipment and metal structures?
- The 2.4 GHz digital wireless transmission is specifically designed to resist interference from two-way radios, cell phones, and the electromagnetic noise generated by heavy equipment. The system automatically selects the clearest channel and maintains connection even when the receiver is mounted on metal components or operating near steel structures. In testing, reliable connection is maintained at up to 150 feet even with obstacles between units.
- What happens if the wireless connection is temporarily lost during operation?
- The RD-100W display provides both visual and audio alerts immediately if it loses connection with the LS-B110W receiver, preventing the operator from working without grade information. The system automatically reconnects within 2-3 seconds once the units are back in range, and the last known grade reading is retained on screen. For critical applications, the receiver also includes a wired connection port as a backup option.
- Is this system compatible with laser levels from other manufacturers?
- The LS-B110W PRO is designed to work optimally with Topcon rotating lasers, but it can detect signals from most standard rotating laser levels operating on compatible frequencies. However, to ensure warranty coverage and achieve the advertised ±1.5mm accuracy, Topcon recommends pairing this receiver with Topcon RL-series rotating lasers. Using non-Topcon lasers may result in reduced accuracy or functionality limitations.
