You must have faith. You may not find out soon. Perhaps this is why people sight fish. But, take heart. Strategy is based on observations regarding the habitat and the creatures that live in it, and tactics on what conventional wisdom and voodoo say will get the job done.
Mechanics involves all the skills needed to execute the plan with the tools at hand.
Actually, it's little different than mowing the lawn or picking the corn. Put together a plan, select the tools and try not to drive over anything not in the original plan. If you cannot actually see the fish you are hoping to catch, which is usually the case, most good fishermen agree that a strategy based upon observations or experiences from a prior trip is advisable. The strategy is to fish points, the tactic to use crankbaits and the mechanics to put the boat in the right spot, while delivering long, backlash-free casts of the distance needed to drive the crankbait to the necessary depth, usually whatever is sufficient to make it ricochet off the bottom. To catch fish that eat bugs, it's usually important to use an insect imitation as close as possible to the size, shape and color of the insect being selected by the fish.
