Line/Point level Bosch GCL 2-15 G

The Bosch GCL 2-15 G is a compact line/point level that projects both a horizontal and a vertical green laser line plus two laser points for alignment tasks. Designed for indoor use, it provides a maximum working range of 10 m and a levelling accuracy of ±0.3 mm/m. The device features a self-levelling mechanism with a working tilt range of ±4° and runs on standard AA batteries, offering up to 22 hours of continuous operation. Weighing approximately 490 g and equipped with a tripod thread (1/4", 5/8"), the GCL 2-15 G is intended to simplify precise alignment, transfer of levels and layout work in construction and installation jobs.

Advantages

The Bosch GCL 2-15 G combines a clear green laser projection with compact dimensions and low weight for easier handling on job sites. Its high levelling accuracy of ±0.3 mm/m ensures precise alignment, while the self-levelling system with ±4° range speeds up setup. Long battery life—up to 22 hours on AA batteries—reduces interruptions during longer tasks. The integrated tripod thread increases mounting flexibility and the dual-function projection (lines and points) covers a range of alignment and transfer applications without the need for separate tools.

Suitable for

• Interior alignment of walls, windows, doors and timber frames
• Installing kitchen units, cabinets and shelving
• Tiling and floor layout where level and plumb references are required
• Electrical and plumbing runs requiring accurate transfer points
• General construction and renovation tasks up to 10 m

How to use

Place the Bosch GCL 2-15 G on a stable surface or mount it on a tripod using the included thread. Switch the unit on and allow the self-levelling mechanism to adjust; the device will automatically level within the ±4° tilt range. Select the required projection mode (line, cross-line or points) and position the laser so the projected reference aligns with your target. For tasks beyond the self-levelling range, manually adjust the instrument until the projected line is straight. Replace batteries as needed to maintain full output; standard AA batteries provide up to 22 hours of operation under typical conditions.

Usage recommendations

Use the green laser in indoor environments with moderate lighting for best visibility. For extended outdoor use or longer distances, consider additional visibility aids or a detector compatible with green lasers. Store the device in a dry, dust-free place and remove batteries if the instrument will be unused for extended periods to avoid leakage and corrosion.
