Delayed Surface Marker Buoys (DSMBs)

DSMBs are similar to SMBs but are designed to be deployed at depth and ascend slowly to the surface. They are typically used for decompression stops or in situations where immediate surfacing is not desired. DSMBs are often equipped with a weighted base to help them maintain their position in the water column.

Torpedo Buoys

Torpedo buoys are long, streamlined buoys that are towed behind a diver. They create minimal drag and are less likely to be entangled in kelp or other underwater obstacles. Torpedo buoys are often used by technical divers or in strong currents.

Lift Bags

Lift bags are inflatable bags that can be used to lift heavy objects or assist divers in ascending. They can also be used as marker buoys by attaching a flag or reflective tape. Lift bags are typically made of durable materials and can withstand high pressures.

Multi-Purpose Buoys

Multi-purpose buoys are designed to serve multiple functions, such as a marker buoy, decompression buoy, or safety sausage. They often feature multiple inflation chambers and can be configured for various applications. Multi-purpose buoys offer versatility and convenience for divers.

When selecting a marker buoy, consider the diving conditions, visibility, and your personal preferences. Choose a buoy that is appropriate for the intended use and provides the necessary visibility and functionality.
