The Topcon RL-H5A Horizontal Self-Leveling Rotary Laser is a multi-purpose laser that is ideal for grading, excavating, site preparation, concrete works, and other general construction projects. With a laser receiver, it offers a long operating range that covers up to 2,600 feet in diameter. This laser level also offers an accuracy of up to ±1/16" or 1/8" at 100 feet and is self-leveling within ±5 degrees. For added precision and accuracy, the RL-H5A features a manual single-axis leveling method, which allows you to match existing single slopes, and rotates 600 times per minute while the self-leveling of the cross-axis provides out of level protection for the opposite axis. The RL-H5A transmitter sends a continuous self-leveled 360-degree laser reference over your entire work area, allowing you to work longer from each setup with greater accuracy. This horizontal rotating laser is simple to use, intuitive and re-levels itself immediately if the device is disturbed on the job. Just turn it on and in seconds you’re working.
