I have the Wicked-supplied nice goggles, but a second person would have to use their own or some sunglasses at least although inadequate. I would need to read through that thread again, it's big. There's a couple vids too. Not for the beginner if you wanna play it safe.
Maybe someone from MASC has the waterproof one. There's another recent Laser thread, dig it up and see how they faired. There's also Aptasia-X or a Copperband...
