An underwater laser would only be useful in the absence of light or night dives if you prefer. Beyond the refraction of the beam due to underwater particles, the color RED is the first color lost from the spectrum as you descend. Havent you noticed when shooting fish at depth that their blood is green?
Lets try a little experiment with a cheap laser
1) Fill a bathtub with water
2) Point laser at bottom of bathtub
3)Try to see the red dot
4)Switch off the light and try again
5)Post Results
Needless to say if one is having trouble seeing the dot in the bathtub OPERATION LASER SCOPE stops there.
