1. Would recommend a green laser rather than red for better visibility outdoors and at long distances. 2. I also recommend a provision for mounting on a tripod. I simply glued a nut into the belt clip at 2-1/2" from the front face. See my pictures, attached. 3. The built-in level should be illuminated or larger and easier to read.
Works very well. Thought it had a problem but that was because I'd misread some of the incredibly tiny print in the manual. After I got a magnifying glass, I figured out what I was doing wrong. (Hard to read manual is the reason I only gave it 4 stars)
