Usage
The Bosch GLL 3-80 projects three 360° laser lines to enable precise horizontal and vertical leveling for interior construction, such as installing ceilings, laying tiles, or mounting shelves.
Advantages
- Projects three clearly visible 360° lines for efficient full-room alignment
- High-powered red diodes ensure excellent visibility across large workspaces
- Self-levels quickly on uneven surfaces up to ±4° in less than four seconds
- Robust IP54-rated housing resists dust and splash water for demanding job sites
- Straightforward operation with an intuitive control interface; requires standard AA batteries (4x)
Specifications
- Design & Materials: Compact ABS plastic housing; integrated pendulum lock for safe transport; suitable for tripod use (1/4", 5/8" threads)
- Durability & Standards: IP54 protection against dust and splashes; operates in temperatures from -10°C to +40°C; storage range -20°C to +70°C; laser class: Class 2 (630–650 nm)
- Performance:
Accuracy: ±0.3 mm/m
Self-leveling range: ±4°
Levelling time: < 4 s
Working range up to 30 m (120 m with receiver)
Power supply: Four AA batteries provide max. four hours in full line mode
Weight: approx. 0.82 kg
- Differentiating Features:
Three independent, simultaneous full-circle laser lines allow multi-surface marking at once
How it works
The device uses high-visibility diodes to project one horizontal and two vertical red laser lines around a room. It self-levels automatically within its range—users position the tool, switch it on, and reference the projected lines for accurate layout and installation tasks.
