Oh! Yes! This one has done the rounds before. It causes nearly as much disagreement as free versus scuba spearfishing.
Having done a lot of experimenting a fundamental problem was discovered. Underwater lasers don't work. A red laser that throws a beam literally miles out of water can't be seen at 6 inches underwater. Lasers that were sold specifically for pointing out things underwater were a con 'cause they didn't work.
The next generation of laser was the green laser. Very expensive. Absolutely massively powerful. Dangerously so. Videos on you tube showed them being used in swimming pools. Tried then in the sea. Crap. Don't work.
My brother Foxfish is the expert and loves his toys but he's never got a laser to work underwater either.
One last point though is that they do work to some extent at night and I have had some fun with them on night dives.
Finally, finally, there is currently a green underwater green laser advertised as a shark deterent. Aparently you shine it in their eyes, seriously!!!!
