Underwater lasers

[underwaterlasers]

Just curious about the interest in underwater lasers. Is there a lot of interest out there in having such a device. I know there are a few on the market already. We have built some prototypes and are just trying to get a feel for the interest for this type of device. We are trying to get a feel for the interest in the marketplace. All my friends that are divers think its a great device, but aren't sure they would really want to include one in their dive. Just wondering if there are others out there that are already using them, or have some critical feedback on why hardly anyone uses them, etc.

Thanks!

Haven't used, but I am interested in the subject.

Would be nice to get some info on the type of lasers and power used/proposed and how far they reach in "troubled water"

Sorry, but what would you do with one? Point at stuff? Get fish to chase the dot?

Not (entirely) a facitious question.

As a pointing device or a weapon? for the record I'm only interested in the latter .

Oh and as a follow up to the above response

Researchers are using calibrated lasers to size fish in stereo video setups. Two lasers in parallel with a known distance apart can be used as a scale bar for accurately sizing many animals in such a scenario. I am unsure of the specs of the underwater lasers they use, but I think it should be a different spectrum than red lest it be absorbed within a few feet.

From personal experience (and several posts on Scuba Board) red lasers don’t work very well in water, even with good visibility.

Reportedly green lasers are better, but I have no personal experience, and they are (or at least used to be) significantly more expensive.

What color are your prototypes?
