A fishing pole with an electric current running through the line (you may want to wear rubber or leather gloves when using this) so that when a fish grabs the hook the current jolts it sufficiently to stun it long enough for you to reel it in without it fighting back.
(edit: changed category from "sport" to "product" since this is obviously not for sport fishing.)-- 21 Quest, Jan 01 2007 xandram, sorry I didn't mean to delete your anno, I accidentally posted this twice, the first one before I was done typing, so I deleted the unfinished one.-- 21 Quest, Jan 01 2007 hey, that's cool, I came back to see if you finished your idea! I don't fish very often, but I would most likely hurt myself with this item. I'll let the fisherman vote on this one.-- xandram, Jan 01 2007 how do you make the current go through the fish as opposed to going into the water around the fish?-- jhomrighaus, Jan 01 2007 I was thinking a switch in the hook, so the electricity is only activated if the fish bites.-- 21 Quest, Jan 01 2007 random, halfbakery
