2. If you don't have a tower then get a buddy to stand up on the anchor locker and holler out directional commands so you can zero in on the fish. The higher up you or your buddy are the farther away you can see and easier to see the fish in the water.
The hard part is just driving around looking for weeds, color changes, rips and junk in the water and seeing if Trips are hiding under it. Some times you'll spend hours looking for them and others they'll be right outside the port, just the nature of the beast when sight fishing.
