swimming flags
Swimming flags are colorful markers used in swimming pools to indicate the location of the turn wall. They are typically placed about 5 yards from the wall, helping swimmers gauge their distance and prepare for a flip turn or finish. The flags are usually made of lightweight fabric and are strung across the pool on a wire or rope.
These flags are especially important in competitive swimming, as they assist swimmers in maintaining their speed and technique during races. The USA Swimming organization often specifies the use of swimming flags in their guidelines for swim meets to ensure consistency and safety.
