Promate 4 Ft Signal Marker Buoy SMB Tube Safety Sausage

The Promate SA048 is a compact 4-foot surface marker buoy designed to help make a scuba diver easier to see at the surface. Its high-visibility safety-orange color provides a clear visual reference for a boat crew, shore support, or nearby traffic while the diver is waiting for pickup or marking a position.

This simple safety tube is inflated orally and uses heat-sealed nylon with binding-taped trim. At 48 inches long, it packs down more compactly than many full-size DSMBs, making it a practical backup marker for recreational dive kits and travel bags.
