XDEEP Closed 140cm dSMB




The xDeep Closed dSMB 140cm is a compact closed cell delayed surface marker buoy to mark a location in the water. Bright orange colour and reflective tape increase the visibility of the SMB and the closed design ensure it stays inflated on the surface.



The dSMB can be inflated easily orally or with a LPI hose and the over pressure vavle allows expanding air to escape to prevent damage.

The top of the SMB has a clear pocket for notes that can be sent to the surface to communicate with surface cover.

Webbing loop at the base of the SMB aids easy reel attachment and a bungee loop holds the dSMB wrapped up when not in use.

A very visible and sturdy, well made dSMB should last along time

This is a nice DSMB feels robust and is very visible, a nice light pocket feature at the top which adds extra visibility options especially for night dives

Well made, smooth operation of valve and inflator. Doesn't fill with water like some. Only down side is the feeble looking bungee for holding it together. Some may find it takes a lot of breath at shallower depths to inflate but I use it with an air gun.
