This XDeep Surface Marker Buoy (SMB) includes a heavy duty OPRV, oral / BCD hose inflator, chemical light stick holder,bungee loop to hold it together and a wrist strap.

A closed SMB is often preferred as an emergency source of buoyancy both on the surface and underwater. The xDeep closed SMB includes a BCD hose inflator connector which can be orally inflated. The SMB has a dump valve / Over Pressure Relief Valve (OPRV) which prevents damage from over-pressure if deployed from depth, it also also the buoyancy to be adjusted like a BCD if used as an emergency buoyancy source.

Size: 140cm (56″) long and 12cm (8″) wide.

140 cm of perfect visibility. A SMB must be visible at a long distance. The bright colour of the XDeep SMB is clearly visible even during unfavorable weather conditions. SMBs are not an advertising banners, therefore the buoy material is free from big logos to make the bright-coloured surface as large as possible.

Emergency buoyancy device in a few seconds. In emergency situations, you may need an additional source of buoyancy to help you or any other diver remain surfaced. The XDeep SMB can be converted in a few seconds into an emergency source of buoyancy by clipping its ends together with a double-ended snap hook. It is an ideal solution since you take the buoy with you every time you dive.

Visible at night and at very long distances. The XDeep SMB is equipped with a special 3M Scotchlite reflective tape with a SOLAS maritime visibility certificate. This perfect fluorescent material guarantees that your buoy will be visible at a very long distance. It is especially important at sea where at night it is very difficult to make out something as small as a surface marker buoy.

Easy to access

The lower part of the SMB is equipped with a shock cord loop to hold the rolled up buoy – you can then clip the buoy onto a D-ring without the need for a pouch. This allows you to access the SMB and open it quickly when it is needed. It also takes up little space and is easer to clear than any buoy holder.

Easy to deploy

The lower loop in the XDeep SMB is stitched to maintain a round shape, which makes it easier to place a spool through or to clip a bolt snap. This small change is a huge convenience and speeds up the deployment of the buoy, especially in poor visibility conditions. A fixed snap hook has not been fitted on purpose, so if the clip was damaged you would not have to unstitch the buoy to replace it.
Space for a chemical light or message. The upper part of the SMB has a transparent holder for a chemical light stick or a paper with information for a surface support team – the perfect solution when you want to pass a message while staying at a deco stop.

Top quality fabric from the USA. The XDeep SMB is made of high quality fabric, Nylon 240 dTEX, made in the USA and destined for application in maritime signalling equipment and life jackets. In production, a special colouring process ensures that the material is more resistant to colour-fading in salty water.

Anti-bacterial coating. A wet environment inside SMBs is an ideal place for bacteria growth. Like XDeep’s BC wings, antibiotic protection has been applied to the shell of the SMBs to prevent the development of micro-organisms.
