Bosch GOL 26CK Auto Optical Level Kit 26X – Accuracy ± 1/16 In. at 100 Ft.

The Bosch GOL 26 CK Auto Optical Level Kit is engineered for jobsite-ready accuracy and durability, built for professionals who require reliable, precise leveling in construction, excavation, and layout work. With a 26x magnification lens and a working range up to 330 feet, this auto level is accurate to ±1/16″ at 100 feet, delivering dependable measurements for grading, leveling, and alignment applications. The self-leveling compensator and integrated crosshairs with Stadia lines support fast, accurate readings even in challenging outdoor environments. Its large aperture allows more light into the scope, giving you a sharper image when sighting over long distances.

The GOL 26 CK includes essential components to get started right out of the box, including a contractor-grade aluminum tripod and 8-ft. leveling rod, all stored in a rugged carry case. Bosch’s IP54 protection rating ensures this tool resists dust and water spray, so it performs reliably even in tough jobsite conditions. The top-mount quick sight speeds up alignment, and the circular bubble vial with 90° prism simplifies setup from any angle. This is a solid choice for crews who need repeatable accuracy day after day without the cost or complexity of laser leveling systems.
