er... wrong choice of tools bro, u should get the night-vision
bino (price should be around $300-$400), u can be much tactical in
this sort of gear rather than torch-light
. Some "advance" fisherman already start using
"night-vision" so I think it will suit your purpose also. Infra-red
torches combine with some good night-vision capable video-cam
should help also... (go find out from "ClubSNAP" for details
LOL)
