HQ Diving Yellow Emergency SMB 150cm – Diver Below

The HQ Diving Yellow Emergency SMB 150cm – Diver Below helps you make your position visible to boats and surface support. Measuring 150cm long and 15cm wide, this fluorescent yellow surface marker buoy combines bold black DIVER BELOW lettering with a reflective strip for a clear, noticeable surface signal.

Designed for use as a delayed surface marker buoy (DSMB), it features an open bottom and integrated oral inflation valve. The automatic over-pressure valve releases expanding air during ascent, helping protect the buoy from over-inflation. After the dive, the quick-dump valve makes deflation straightforward, and the elastic retaining bungee keeps it neatly rolled for storage.

For divers using an agreed emergency-signalling system, this yellow SMB provides a distinct marker to request assistance from surface support.

• Highly visible yellow colour: Fluorescent fabric helps the buoy stand out against the water.
• 150cm length: Creates a prominent surface marker while rolling down for convenient storage.
• Bold DIVER BELOW lettering: Clearly identifies the presence of a diver beneath the marker.
• Reflective strip: Reflects light from a suitable light source to help the marker attract attention.
• Flexible inflation options: Open-bottom construction accommodates inflation from an alternate air source or regulator exhaust, with an integrated oral valve providing another option.
• Automatic pressure relief: Vents expanding air as the buoy ascends to reduce excessive internal pressure.
• Quick-dump valve: Releases air efficiently for easy packing after use.
• Durable construction: Abrasion-resistant material is designed for regular use in diving environments.
• Spool and reel attachment: An integrated attachment point connects to a suitable finger spool or dive reel.
• Compact roll-up storage: The retaining bungee keeps the deflated buoy secure in a suitable BCD pocket, thigh pocket or dive pouch.

Yellow emergency signalling: Yellow DSMBs are used to indicate an emergency or request assistance in some diving procedures, particularly technical diving. This meaning is not universal. Agree on buoy colours and the expected response with your buddy, dive team and surface support before entering the water.
