Fully waterproof 445nm laser pointer?

[xivlia]

Hello there, i know i have low rep...

but, i am gearing up for night spearfishing for when i go to turkey this summer, and i am looking to make a 1w laser pointer, but it needs to be FULLY waterproof, up to 15meters minimum.

i was thinking something on the lines of, being fully silicon sealed so no water can get in, and having two metal contact points on the host to charge, so i wont need to remove the batteries.

is something like this possible?

also probably need some sort of glass lens over the headsink and silicon seal that too so water doesnt leak in.

i need to beam to be out of focus so it covers a larger area of the sea.


i will also ofcourse be using diving torches attached to my wrist etc

I remember seeing waterproof lasers on rayfoss, but I don't have one. Maybe someone here bought one and can chime in on the subject.

I think a flashlight would be better applied to what you're doing.

I agree, just get a flashlight...

My C6 host spent a night in the hot tub and was completely dry inside, still can't figure out how it ended up in there but, no damage
