For successful pier fishing, particularly when targeting bass, there are several key pieces of equipment and techniques that can enhance your chances of a good catch.

Firstly, let's talk about equipment. A versatile baitcasting or spinning setup is essential. For baitcasting, a medium-heavy rod with fast action, paired with a reel that has a good drag system, will give you the power and sensitivity needed for fishing around structures. Spinning gear can be used as well, especially for finesse techniques; a medium power rod with a fast action is a good choice. As for line, fluorocarbon in the 10 to 20-pound test range is often recommended due to its low visibility and good sensitivity.

Now, onto techniques. Based on the video context provided, here are some strategies:

1. Water Clarity Consideration: As Randy Blaukat mentioned, water visibility is crucial when fishing bridge pilings. In clearer water (ideally 3 to 10 feet visibility), bass are more likely to suspend and use the structure for cover. In such conditions, a swimbait or a drop shot rig can be very effective.

2. Targeting the Right Areas: Focus on the upstream and downstream sides of the pilings, as well as the sides. These areas often hold bass looking for current breaks and food. Parallel casts to the structure can be very effective.

3. Lure Selection: Depending on the species of bass and water clarity, your lure choice may vary. For mixed species lakes with clear water, small swimbaits and drop shot rigs can be effective. For largemouth bass, consider using jerkbaits like the Megabass Vision 110 or topwater walking baits if the water is clear.

4. Fishing Boat Docks: When fishing around boat docks, look for metal pilings, steel cables, and man-made structures. These can hold more fish than the docks themselves at times. Creature baits that skip well, such as the Yum Christie Critter, can be flipped around these structures with a consistent weight like a 5/16 ounce to maintain accuracy.

5. Finesse Techniques: For docks, using finesse techniques with lighter line (10 to 12-pound fluorocarbon) can be effective. Work the bait from the outside in, targeting key areas like corners and gaps between pilings.

Remember, the approach can vary based on the specific conditions you're facing, so it's important to adapt and experiment. If you're fishing in an area with current, don't assume bass will only be behind pilings; they can be all around, so cover different angles.

Always be ready to adjust your techniques based on what the bass are responding to and the conditions of the day. Happy fishing!
