"...Some fish are even attracted to the red light and will chase the beam!"... - from description.
Garett. Old Man Dave & myself brought that very same laser! We carefully fitted them to our guns & excitedly tired them out in the water. As I said they dont work!!!:head You can see the beam very nicely out of water but at 6'' underwater you could not! I contacted the company in question to complain but they never replied.
Not surprisingly I am reluctant to buy the same company's green model in fear of that not working either. However I am lead to believe that green lasers do in fact work underwater??

The ultimate conclusion of this approach is pair trawling :rcard If you need to resort to gizmo's like these then there is something wrong with your basic skills (a generalism, not aimed at you matefoxfish said:Personally I think it is a good idea to pursue any method that helps me catch my tea. Water proof green laser pointers can be found on the net for about $350.
Chad Carney said:Simply put, you don't need a lazer to aim a speargun.
Spearfishing is done in relatively close confines, so even from the hip, the angle of the shot is easy enough to figure out.
foxfish said:Laser sights have been through the DB washing machine several times before. lt would seem this type of technology is too much for some members to deal with.
Shadowkiller said:Controversial? Maybe, more like a waste of money.
Situation 1: Shooting moving fish where you aim ahead of them in order to hit them. Laser is useless...
Situation 2: Fish moving slowly or stationary within 1-2m of the tip of the gun. Do you really need a 300 buck laser pointer to hit them?
Situation 3: Fish is more than 2m away. Good luck finding a laser with a focused enough beam that it wont diffract into nothingness. Now hope for perfect viz as any particles in the water will deflect/reflect the beam.. Laser is pretty useless...
The transmission of energy through dense, moving medium, like water, is very, very different to air.
