A laser is not a totally dumb idea. I would not use one, but it does not mean I think it's dumb or bad. But unless every fish you shoot is sitting still, then it may not be too practical imo.
As far as the learn to shoot your gun...it's a good comment, but could be taken as an insult. But yes, learn your gun, where it shoots and how it shoots at various distances. It is like a hand gun or rifle on land. Good shooters, the gun is an extension of them and the aim is natural. Lasers and such make the average shooter more accurate, but they will never be the pure shooter like the guy that practices his reactive skills continually.
