Topcon RL-H5A Self-Leveling Rotary Laser Kit | 800m Range, IP66, LS-80 Receiver, Field Book

Rugged reliability for real-world construction

The Topcon RL-H5A is a self-leveling horizontal rotary laser built to endure dust, weather, and daily wear on active job sites. It can cover a diameter of up to 2,600 feet (800 meters) with a high accuracy of 1/16 inch at 100 feet. The electronic self-leveling system starts with a simple power-on and maintains level within a ±5 degree range, while a height-of-instrument alert keeps crews informed of elevation changes.
