TecLine Surface Maker Buoys Semi-Closed SMB's

The Tecline Semi-Closed Surface Marker Buoy (SMB) is a robust and high-visibility signaling device designed for diver safety. It features an Over Pressure Release (OPR) valve to prevent over-expansion when deployed from depth. The semi-closed design allows for easy inflation with minimal air loss, ensuring it stays inflated on the surface. Available in bright orange or yellow, it enhances visibility in various conditions, making it essential for divers signaling their position or marking safety stops​
