Bosch GOL 26 D Professional Optical Level Set

The Bosch GOL 26 D Professional Optical Level Set is a complete surveying kit designed for accurate levelling on construction sites and civil engineering projects. Built around a 26x magnification optical level with IP54-rated dust and splash protection, it is well suited to outdoor use in demanding site conditions.

The sturdy metal housing makes this optical level exceptionally resilient, standing up to the rigours of daily site work without compromising accuracy. With a working range of approximately 100 metres and a levelling accuracy of ±1.6 mm at 30 m, it delivers reliable results for setting out foundations, checking gradients, and establishing level datums across a range of trades applications.

A built-in target collimator and integrated circular vial simplify alignment and setup, helping to reduce time on site. The compensator lock protects the instrument during transit, and the standard 5/8" tripod thread ensures broad compatibility with other surveying equipment. Operating across a temperature range of -10 °C to +50 °C, it remains dependable in typical UK site conditions throughout the year.

This set includes everything needed to get to work straight away, with the building tripod, measuring rod, and carrying case supplied as standard — making it a practical choice for contractors and groundworkers who need a self-contained levelling solution.
