What is "high flyer"

n. (alternative form of highflier English)

High Flyers, also known as Long Line High Flyers, are vertical poles used by commercial fishermen that serve to locate the beginning and end of a long fishing line, commonly used in tuna, swordfish, as well as other fishing. Often constructed with a vertical Marine Grade aluminum pole which resists corrosion, they have a tapered fluted buoy to provide buoyancy, and the poles are about 6–9 feet (2–3 meters) high above the water. The counter-weight at the bottom is often a PVC pipe filled with concrete. The High Flyer is tipped with an aluminum radar reflector that warns ships from a distance of a line between two High Flyers.
