Spooli is a term that can refer to several different things, primarily related to winding or storing materials. In the context of fishing, a spooli is a small spool of line, typically made of monofilament, fluorocarbon, or braided material, that is loaded onto a fishing reel. This spooled line is what allows the angler to cast their line and retrieve fish. The type and amount of line on the spooli are chosen based on the fishing conditions and the target species. More broadly, "spooli" can also be used informally to describe any spool or reel that holds a length of material, such as thread on a sewing machine, wire on a spool, or film in a camera. The act of winding material onto such a device is often referred to as "spooling." For example, one might spool thread onto a bobbin or spool cable onto a reel. The term emphasizes the function of holding and dispensing a continuous length of a flexible material. The origin of the word is related to the spool, a cylindrical object used for winding.
