The fisherman shown on the right caught his huge largemouth bass while visiting friends in North Carolina using a spinnerbait lure.
Spinnerbaits were sometimes called "safety pin lures" because they have a frame like an open safety pin with two arms sticking out from a tie point. One arm contains a leadhead and a hook covered by a soft plastic or silicon string skirt. The other arm contains one or two spinner blades. Most spinnerbaits have two spinners. One is a round, spoon shaped Colorado blade optimized to make vibrations, and the second is a longer Willowleaf blade optimized to flicker and flash.
Thus, the lure attracts bass visually by flash and also by sound or vibration via a fish's lateral line. This allows them to work in both clear and murky water and even at night. Use a lure with smaller blades in shallow water and one with bigger blades in deep water.
With a spinnerbait you can cover a lot of water in a short time. The leadhead allows it to be cast far. Cast it out and after it lands give it a little jerk to get the blade spinning, then start your retrieve. Often a steady slow or medium speed retrieve works well, but also try a little stop and go to give it an erratic action like a wounded baitfish.
The lure sometimes makes a noisy splash when it hits the water after a cast. A good technique is to mark where you think the fish are, then cast well past them. Let your retrieve move the lure to where you targeted the fish.
