Product details

The GRL18V-3-31G rotary laser is designed for comfort and reliability. The simple one-button interface makes operation intuitive and saves time on every job. It is built for rugged environments, featuring protective handles and a reinforced top cover, and offers IP66 protection against dust and water to minimize interruptions even under challenging conditions. The dual power supply gives you the flexibility to use either 18V lithium-ion batteries or 4 alkaline C cells with the BA 18-C adapter. This results in less downtime and allows you to remain productive even with weak batteries. This rotary laser is perfect for outdoor applications such as excavation, concrete pouring, and landscaping. Use it to determine cut and fill levels or to set up concrete forms. The GRL18V-3-31G is compatible with the new LR3-2 laser receiver, ensuring precise results for demanding tasks. With an impressive accuracy of ± 1.5 mm at 30 m and an extended self-leveling range of ± 15%, it provides the necessary precision for better and more efficient results.
