The Tolsen MP20V is a cordless green laser level designed to provide precise alignment across large workspaces. It utilizes an Osram laser unit with a 520 nm wavelength to project three 360° lines, allowing you to establish horizontal and vertical references simultaneously. With a range of 30 meters and an accuracy of ±3 mm at 10 meters, it handles significant distances while maintaining a self-leveling range of ±4° to correct minor tilts automatically. Built for demanding environments, the tool features an IP54 protection rating and can withstand drops from up to 1.5 meters. It operates reliably in temperatures ranging from -10°C to +50°C, making it suitable for various seasonal conditions. For outdoor projects, you can use the pulse function in combination with a laser receiver to maintain visibility over longer distances. Power is supplied by a 20V Li-Ion 2.0 Ah battery that offers a runtime of at least 15 hours, ensuring you can complete extensive tasks without frequent interruptions. The set comes in a shock-resistant plastic box and includes a charger, a nylon stand, a sheet metal cup, a green target board, and protective green glasses to help you work safely and efficiently.
