Johnson’s 40-6657 Self-Leveling Cross-Line Laser comes with a magnetic bracket so it can attach to all ferrous metal surfaces for hands free use. This laser also can project one horizontal, vertical or cross-line beam simultaneously or individually. Made with GreenBrite® Technology, this laser’s green beam is 400% more visible than red beams. It even adds a pulse mode for the cross lines for use with a detector (sold seperately), for use where the lines aren’t visible, such as in bright light or outdoor conditions.
