Surface Marker Buoys

Surface Marker Buoys (SMBs & DSMBs): Be Seen, Be Found!

Want to significantly increase your visibility to boats and your surface support crew once you surface? Surface Marker Buoys (SMBs) and Delayed Surface Marker Buoys (DSMBs) are brightly colored, inflatable signaling tubes designed precisely for this purpose, making your position clearly known at the surface.

These signaling devices are a key piece of equipment for many diving situations:

• Alerting Boat Traffic: Their primary role is to alert nearby boats that divers are below or are in the process of ascending.
• Marking Your Location: Very useful during safety stops in open water, while drift diving, or to help your dive boat locate you after you've surfaced.
• Ascent Reference: A DSMB deployed from depth can provide a visual reference for your ascent path for yourself and your buddy.

What You'll Find in Our Selection:

We offer a variety of these inflatable signaling tubes to suit different needs and preferences:

• Different Sizes & Styles: From smaller, easily stowed DSMBs to larger surface marking buoys.
• High-Visibility Colors: Typically in bright orange, yellow, or pink for maximum detection.
• Inflation Methods: Options for oral inflation, connection to a low-pressure inflator hose, or self-sealing designs.
• Features: Some models may include over-pressure relief valves (OPVs), dump valves for deflation, and attachment points for your reel or spool line.

Using an SMB or DSMB is a common practice for divers wanting to enhance their presence at the surface. Consider your typical diving conditions and how you plan to use your surface marker when making your selection.
