Projecting Custom Angles with a Speed Square

What happens here

To project custom angles, such as a 45-degree angle, you can combine the laser level with a speed square. First, use the speed square to mark or visually reference the desired angle on a surface, for example, by lining up the 45-degree mark on the square with a horizontal line created by the laser. Then, put the laser level in its 'On and Locked' position (bypassing auto-leveling). This allows the laser to project a line at any angle it is tilted. Tilt the locked laser level until its projected line perfectly aligns with the previously marked 45-degree angle from the speed square. This method effectively extends the angle across the entire surface.

Goal: Accurately project custom angles beyond just horizontal and vertical.
