Line level Bosch GLL 3-80 C Professional

The Bosch GLL 3-80 C Professional line level provides 3 x 360° visible lines for alignment and layout tasks. It delivers self-levelling performance with a range of ±4° and a stated levelling accuracy of ±0.2 mm/m, and can be used with either the supplied 12 V Li-ion battery or standard alkaline batteries. The compact, robust unit (IP54) is designed for on-site use and supports remote reception up to 120 m when used with an appropriate LR receiver (LR 6 or LR 7 Professional, optional).

Advantages

The device combines dual power options—rechargeable 12 V Li‑ion battery or conventional alkaline cells—offering operational flexibility. Self-levelling engages quickly (within about 4 seconds) and maintains high precision, while the 3 x 360° projection simplifies continuous reference lines around a workspace. The compact, easy-to-handle housing is dust- and splash-protected (IP54) and includes tripod threads (1/4" and 5/8") for stable mounting.

Suitable for

• Interior and exterior alignment and layout tasks
• Installing ceilings, partitions and wall tiles
• Electrical and plumbing installations requiring continuous reference lines
• Surveying with a compatible LR receiver for extended range

How to use

Place the GLL 3-80 C on a stable surface or mount it on a tripod using the 1/4" or 5/8" thread. Switch on the unit and allow the self-levelling mechanism to engage (typically within 4 seconds). Select the required projection mode to generate horizontal and vertical 360° lines. For longer-distance detection, pair the laser with an LR 6 or LR 7 Professional receiver and follow the receiver instructions for alignment. Replace or recharge batteries as needed according to the power source in use.

Usage recommendations

For accurate results, set the instrument on a stable mounting, keep the laser lenses clean and use the LR receiver in bright conditions or at long ranges. Observe local safety regulations for laser devices and wear protective eyewear if required.
