Bosch GCL 12V-50-22 CG Professional, 25 m, 0.3 mm/m, 4°, 50 m, 500-540 nm (< 10mW), Line/Point level

The Bosch GCL 12V-50-22 CG Professional combination laser is a robust and precise tool for leveling in demanding conditions. Its durable rubberized housing with an IP65 rating ensures a high level of protection against dust and water. The device projects green lines and dots (up to 4 times more visible than red ones), which can be controlled remotely via Bluetooth using the Levelling Remote mobile app.

The laser uses Dual Power (12V Li-Ion rechargeable battery or AA batteries) for continuous operation. It features a U-shaped laser window for a wider horizontal line angle, an always-on receiver mode to extend the range up to 50 m, and is ideal for installing drywall, light fixtures, and electrical wiring.
