XDeep Closed DSMB 90cm - Compact Safety Marker Buoy for Scuba Diving & Technical Diving - Emergency Surface Marker for Underwater Signaling & Safety

This shorter version allows easier oral inflation or drysuit hose inflation. The drysuit hose method ensures a much larger volume of gas is added to the bag helping to ensure that it is as full as possible when reaching the surface.

It is equipped a reliable over-pressure dump valve, allowing safe and easy inflation via the low-pressure inflation hose. 

The handy small plastic tube on the top side of the SMB offers a place for your glow stick in nigh-time.

The Nylon 240 dTEX material, together with the 3M reflective stripe, make the SMB extremely durable and recognisable even at night.
