Dive Alert DMB4S Surface Marker Buoy – 45" Closed-Circuit SMB, Steel Inflator Valve

Product Details

The DiveAlert DMB4S Surface Marker Buoy (SMB) is a compact 45-inch closed-circuit surface marker designed for scuba divers who need a highly visible surface signal or redundant flotation. The DMB4S features a steel-tipped inflator valve and can be inflated using a BC low-pressure inflator hose or by mouth.

Features

The closed-circuit construction helps prevent air from escaping at the surface. An over-pressure valve (OPV) helps prevent overinflation and allows air to be released when needed. The buoy has a nylon D-ring at the top for attaching a light or slate and a stainless-steel D-ring at the bottom for attaching a spool or reel. A utility pocket provides space for a finger spool or other small items.
