Lets say you have a brush pile in the middle of a cove in about 26 ft of water, you can spider rig through it with minnows and catch fish and also hang up 5 or more rods at once. Seems like you could throw a marker bouy on the structure and cast a jig into it and work it through it or just let it fall into it like when shooting a dock or bridge piling or a tree that fell off the bank. I consider myself pretty good with a jig but cant catch off shore fish with it. I've tried this with a couple good brush piles with no sucess...why???
