Spend some time riding around and looking at your sounder for drops, hard bottom, or any kind of structure.
While you are “scouting” the area keep your eye out for old men in old boats and the guides. Dont crowd them, but do what they did on the following tide. If they were fishing creek mouths on the outgoing, you should ape them. Likewise, if they were fishing docks at high tide, do that.
Fish are hard to “pattern” when you first start in the salt. Only two things that I know of will remedy that, one is time on the water and the other is observing the old guys and the pro’s because they are much easier to figure out than the fish, lol.
Its called fishing, not catching. Not trying to be a smartarse, but if you sit in a spot for 5 or 10 minutes and nothing is going on, just move. Lots of times you don’t have to move far, but move you must.
Dont be afraid to drop the troller and drift along with the tide and pitch baits at the bank, especially at the drops, hard bottoms, and structure you found while scouting around.
June, July, and August are the hardest times for guys learning salt water. In September thru mid December things are much differernt/better. In the meantime, don’t stress on the fact that you aren’t catching big reds, just keep a line wet and things will fall in place.
