A trophy fish will usually not give you more than a fleeting second before he bolts from under a ledge or wreck, and your eyes have not yet begun to adjust to the dim light. A light mounted under a speargun can illuminate your prey when you have little or no chance of spearing the fish otherwise. After the first shot, when extracting a fish, it can be even more important to line up the kill shot.
I remember the Seabear gun and laser sights, and I bought a small number of them for our shop, despite the poor track record of most short pneumatic guns. They looked really cool and were heavily promoted. They were gone within a few years.
IST makes a laser in the housing of the Princeton Tec 40 light. We made a light holder for that light, and I still have a few. I don't recommend a laser however.
You want to be able to see your target, thats all.
Aiming a speargun is a skill aquired with hand/eye coordination, not a laser. Spears will drop a certain amount, and the shooter will only be able to determine this if he has shot his gun hundreds of times.
Presently we make light holders for Pelican Mitylite 4aa lights and UK miniQ 40 lights.
You can see them on

They mount easily to the wood stocks of Wong, Seahornet and Riffe guns.
The light holder is also the front part of a two piece side shaft holder, available for one or two spare spears.
To my knowledge we are the only manufacturer anywhere of a light holder for spearguns.
