If any item holds special mysticism among fishing gear, it’s the lure. Most lures are commercially made, but some are hand-made by the angler (such as hand-tied fly lures, which is considered a hobbyist challenge by many amateur entomologists). Modern lures are typically cast and manipulated with a fishing rod and retrieved with a reel, but there are some who use a technique where the line is directly held with hands (known as handlining) rather than manipulated through a rod. Longlining and trolling, commonly used for commercial fishing, also can employ lures to catch fish. When used for recreational fishing, the lure is repeatedly cast out far and then reeled back towards the angler, and during retrieval it interacts with the water current and drag, creating vibrations, turbulent splashes and/or a popping action. A skilled angler can explore many possible hiding places for fish through lure casting under logs, grass and on flats.
