Inflatable dive marker buoy with anchoring system and PVC dive flag — designed to improve diver safety and visibility with fast setup and compact storage. Key benefits Improves safety and visibility: the included PVC dive flag makes your position easy to identify from the surface and underwater, helping skippers and other water users spot you. Stable, upright marker: a sand hole at the bottom secures the sphere in place so the buoy remains upright and visible in current or swell. Fast setup and compact storage: inflates in about 30 seconds and deflates quickly for easy packing and transport. Simple attachment: built-in hook accepts standard rope for towing or securing to a line. Main features Anchoring system: bottom sand hole designed to take sand as a simple, reliable stabilizer and keep the sphere upright. Rope attachment: integrated hook for fast connection to your dive line, boat, or surface buddy. Personal safety signal: PVC dive flag attached to the buoy for clear location identification. Inflation/deflation: quick 30-second inflation; straightforward deflation for compact storage between dives. How it solves common problems Keeps you visible to boats and surface teams, reducing collision risk. Stays upright in variable water conditions so the flag remains readable. Eliminates lengthy rigging—get the marker in the water and inflated quickly. Packs down small so it does not take space in your gear bag. Quick deployment (typical) 1. Inflate the buoy — about 30 seconds by pump or manual inflation. 2. Add sand through the bottom hole to stabilize the sphere and keep it upright. 3. Attach your rope to the hook and secure to your diver line, boat, or anchor point. Practical use scenarios Shore entry dive: inflate, fill the sand hole to stabilize, and tow or anchor the buoy to mark your exit point for surface support. Drift or open-water dive: deploy and attach to your SMB or line so boats and support craft can see your location at a distance. Training or group dives: use as a clear surface marker during instruction, buddy checks, or surface intervals to maintain team visibility.
