I was thinking the same as what Sam posted. Any light that would make a difference would have too narrow a beam for a spearfishing application. Unless you were doing some "macro" shooting. Besides, carrying a light on top of everything else would take the fun out of the dive I think.
With the one day old price drop on the hero3 GoPro HERO3 Black Edition - $329.99 it's a great time to upgrade and save some cash. But it may also be a good time to wait as something new from Gopro could be around the corner, for which you'll probably pay the non discounted price but get more value.
