DiveAlert DMB2 Surface Marker Buoy with Utility Pocket

DiveAlert DMB2 Surface Marker Buoy with Utility Pocket for Scuba Diving

The DiveAlert DMB2 Surface Marker Buoy (SMB) is a durable, high-visibility inflatable buoy designed to help scuba divers communicate their location and improve visibility during diving activities. Featuring semi-closed-circuit construction with a one-way valve, this surface marker buoy helps prevent air from escaping when inflated at the surface. Divers can also deploy it from depth to create a visible surface reference for boat crews and other water users.

Constructed from durable 400 Denier polyurethane-coated nylon, the DMB2 features a 65-inch length, approximately 8-inch width, and 40 lb lift capacity. SOLAS reflective tape across the top improves visibility during daytime and nighttime conditions, while the integrated over-pressure valve helps release excess air to prevent overinflation. Unlike the standard DMB1, the DMB2 includes an additional utility pocket for a finger spool, small accessories, or added weight for improved stability in rough water.

Why Choose the DiveAlert DMB2 Surface Marker Buoy

• Semi-closed-circuit construction with a one-way valve helps prevent air loss at the surface.
• Can be inflated at the surface for visual signaling or additional flotation.
• Can be deployed from depth as a surface marker to communicate a diver's location.
• SOLAS reflective tape improves visibility during daytime and nighttime conditions.
• Integrated over-pressure valve helps prevent bursting from excess internal pressure.
• Additional utility pocket provides storage for a finger spool, small accessories, or added weight.
• Durable 400 Denier polyurethane-coated nylon construction for repeated diving use.
• Top nylon strap handle provides an attachment point for a dive light or slate.
• Multiple inflation options provide flexibility during diving activities.

Easy Inflation and Deployment

The DiveAlert DMB2 offers multiple inflation options to accommodate different diving situations. It can be inflated using a BCD low-pressure inflator hose, by mouth, or with a compatible second-stage regulator. Its one-way valve helps retain air after inflation, while the integrated over-pressure valve releases excess pressure to help protect the buoy from overinflation. The utility pocket provides convenient storage for a finger spool or other small accessories, while the top nylon strap allows attachment of a dive light or slate.

Perfect For

• Recreational scuba divers.
• Technical and advanced divers.
• Boat-based diving operations.
• Divers who need a visible underwater-to-surface signaling device.
• Divers who prefer multiple SMB inflation options.
• Divers carrying finger spools and small signaling accessories.
• Diving activities requiring improved surface visibility and location marking.

Improve Your Surface Visibility and Dive Signaling

Stay visible and keep essential signaling accessories organized with the DiveAlert DMB2 Surface Marker Buoy. Combining durable nylon construction, reflective visibility features, a one-way inflation valve, an integrated over-pressure valve, and a practical utility pocket, this SMB provides a versatile signaling and flotation option for recreational and technical diving activities.

Important: Always follow the manufacturer's inflation and deployment instructions. Use appropriate buoyancy and line-management techniques when deploying an SMB underwater. The stated 40 lb lift capacity is approximate and should not be treated as a substitute for a properly rated BCD or other primary buoyancy system.
