Topcon RL-H5A Self-Leveling Rotary Laser – 2600 ft Coverage, IP66 Construction Kit

Reliable construction laser for serious job sites

On demanding sites, precision and dependability matter. The Topcon RL-H5A self-leveling rotary laser blends rugged build with proven accuracy to help teams maintain grade and alignment from first light to last call. Its long-range reach supports large layouts, while a straightforward workflow keeps crews moving. With thoughtful touches like a height-of-instrument alert and an EDEN field notebook included, you have a practical partner for grading, excavation, and general construction tasks.

Performance that travels with you

The RL-H5A delivers wide-area coverage and stable leveling in real-world conditions. Highlights include a 2,600 ft diameter reach, 1/16 inch accuracy at 100 ft, and a leveling range of ±5 degrees. Electronic self-leveling allows operators to focus on the task at hand, while the HI alert signals elevation changes so teams can adjust quickly on the fly.

• Diameter coverage up to 2,600 feet (800 meters) for expansive layouts
• Self-leveling accuracy of 1/16 inch at 100 feet
• Leveling range of ±5 degrees for uneven terrains
• Electronic self-leveling with a clear height-of-instrument alert
