…or, looking for tips on stuff that are useful to have that most people don’t think about.

        Don’t listen to [email protected] your privacy is being illegally invaded and your every move tracked. Sanwu Lasers dot net. Get a 3w one with the focusing lens at the least. But you’ll need safety goggles to operate a 3w focused beam and anything higher. DO NOT shine these where they could intercept with a person.

          Would I be right in thinking that viewing the beam alone isn’t damaging, but looking at the lens is? Presumably then, unintended viewing could be limited if not eliminated by shining it through a tube?

            No one should be viewing any of it without goggles. It will damage your vision after just a few seconds of indirect exposure, direct exposure (pointing it at your eyes) will blind you.

              Glad to know I was quite wrong. Thank you for potentially saving my vision.

              Not knowing much about lasers myself obviously, is a welding helmet be sufficient protection from indirect exposure?

                Yes, with my 3w, I can use it periodically without goggles but I cannot look at the beam for more than a few seconds. A welding helmet will protect you completely. It does make it hard to use with precision at night tho.
