Purpose and benefits Designed primarily as a surface marking buoy for diving to improve safety and visibility during ascents, decompression stops, and boat pick-ups. Versatile enough to double as a recreational toy for surface play, training or swim practice. Solves common problems: makes divers easy to locate from the surface, signals your position to boats and shore support, and provides a visible reference for safety stops. Key features Size: 150 cm x 15 cm; long profile provides clear visibility at the surface and underwater. Dive signal design: duckbill SMB (surface marking buoy) that deploys quickly and remains visible. Inflation options: can be inflated by mouth, by a second stage regulator, or by a BCD inflator—compatible with standard diving gear and convenient in the water. Package contents: each package contains 1 buoy. Practical performance Visible profile helps reduce the risk of being missed by boats or surface personnel during ascents and drift diving. Simple, reliable inflation methods let you deploy the marker even if a primary air source is unavailable. Lightweight and easy to handle in the water for single divers or buddy teams. Typical use scenarios 1. Drift or open-water diving: deploy the SMB during ascent or a safety stop to mark your position for the boat crew and other water users. 2. Shore diving or group dives: use the buoy to indicate your location to surface support and to coordinate rendezvous points. 3. Recreation and training: use as a toy or visual target in pool or calm-water sessions for swim practice or dive skill drills. How to use Inflate using mouth, a second stage regulator, or a BCD inflator until the buoy is firm and deployable. Secure the buoy to your diver via a reel or line as required by your dive plan and local regulations. Pack one buoy per diver as included in the package. This buoy offers a straightforward, reliable surface-marking solution that enhances diver visibility and safety while remaining adaptable for recreational use.
