The Tolsen 35155 is a 3D green laser level designed to provide full spatial coverage by projecting three 360-degree lines. It utilizes an Osram laser unit with a 520nm wavelength, which ensures the green beams are highly visible across a working distance of up to 30 meters when used without a detector. For precise alignment, the device maintains a beam accuracy of ±3mm per 10 meters across both horizontal and vertical planes. Built to handle demanding environments, the tool features an IP54 rating for protection against dust and splashes, and it can operate in temperatures ranging from -10°C to +50°C. You can power the unit with a 3.7V Li-ion battery that charges via USB, offering a runtime that varies based on your needs: 15 hours for a single line, 10 hours for two, and 5 hours when all three lines are active. It also includes an outdoor pulse mode for extended reach and multiple line switching functions to focus only on the planes you need. To keep the device stable, the base is equipped with both 1/4" and 5/8" threaded holes for compatibility with various tripods. The set comes housed in a durable blow mould case and includes the instrument, a back clip, the battery and charging cable, as well as a green target board and glass to help you spot the beams more easily in bright light.
