- Safety signal indicator: This dive buoy provides a clear signal to indicate divers below, helping others easily find your location. It serves for both location marking and notification marking, allowing quick identification of signal markers while swimming. - Inflatable and portable: The buoy inflates in about 30 seconds and deflates quickly for compact storage. It folds flat and can be stored in your dive bag for convenient use and transport. - PVC material and durability: Made from high quality PVC, the buoy is UV resistant and will not fade with long-term sun exposure, suitable for continuous use outdoors. - Stable standing and easy positioning: A sand hole at the bottom helps fix the buoy and keep it upright. The built-in hook allows attachment with a rope for easy positioning, enabling rapid identification in the water. - Use scenarios: 1) Open-water diving or snorkeling to mark your position and improve safety by making you easily visible to nearby swimmers and boat traffic. 2) Group swims or training sessions to maintain visibility and quick signaling among teammates. 3) Shore or boat-based water activities to designate a swimmer’s location on the surface for quicker retrieval and safety confirmation.
