Just thought I would share this with you all. My dad has this yellow level that has a laser dot in the end. I used a screw to mount it to the cabinet where I work on my cams. The level already has a hole to mount it with. Then, you can level the level so it is straight up and down. The dot is just the right size. It looks larger in this picture than it actually is. The dot is about the size of the end of an ink pen. My wife just got an ltd book and it has these same levels for less than $10. I think it was $9.95. It works perfect.
