Optical Level Bosch GOL 32 G Professional — 400 gon, with tripod

Optical Level Bosch GOL 32 G Professional is a precision optical surveying instrument with a 400 gon (grad) circle, supplied with a field tripod for stable setup. Designed for leveling and height transfer on construction and surveying sites, the instrument provides clear sighting and accurate line-of-sight measurements for setting out foundations, grading and alignment tasks. The included tripod allows quick, steady positioning and adjustment on uneven ground, making the system ready for immediate field use.

Advantages

The Bosch GOL 32 G offers robust optical performance with a fine 400 gon circle for angular measurement in grad units, combined with a stable mechanical leveling mechanism. Its integrated telescope provides clear, repeatable sighting and a wide working range suitable for common site tasks. Supplied with a tripod, the kit reduces the need to source separate mounting hardware and improves workflow efficiency during repeated setups. Construction-grade build quality and straightforward controls simplify routine surveying operations.

Suitable for

• Leveling and transferring heights on building sites
• Establishing grade and slope for drainage and landscaping
• Setting out foundations, formwork and structural alignments
• General surveying tasks requiring optical line-of-sight measurements

Key specifications

• Angular circle: 400 gon (grad) for measurements in grads
• Optical telescope: precision optics for clear sighting and reliable targeting
• Included tripod: field tripod for stable support and adjustable height
• Leveling mechanism: mechanical leveling suitable for typical construction tolerances
• Working range: designed for standard construction and surveying distances

How to use

Set up the tripod on firm ground and extend its legs to a comfortable working height. Mount the Bosch GOL 32 G on the tripod head and secure it with the locking mechanism. Use the foot screws or fine leveling controls to bring the instrument’s bubble to center and ensure the instrument is stable. Aim the telescope at the target or levelling staff, focus the optics for a sharp image, then read angular or height differences using the 400 gon circle and the staff readings. Recheck leveling after relocating the tripod or making large adjustments to preserve measurement accuracy.

Recommendations

Keep optical lenses clean and protect the instrument from moisture and strong impacts. When transporting, use a protective case and handle the tripod and instrument carefully to avoid misalignment. For best results, perform routine checks and calibrations according to site requirements and manufacturer guidance.
