No pool should ever be in use without a Life Hook nearby. The Life Hook attaches to any standard straight pole (sold separately). The Life Hook is a handy aid to help swimmers in an emergency or useful in instruction. If someone seems to be drowning just extend the Life Hook out towards them and maneuver it around them to get the person to safety. Hook and handle made from durable anodized aluminum that will not break under pressure. Do not use on a telescopic pole. Ideal for teaching and emergencies.
