I'm having problems finding a good quality SMB in Sharm el Sheikh, Egypt. The SMB I bought recently leeks like a sieve, and the other confirgurations on sale here are cheap and nasty. Any pointers? thanks

Udo Hartig:Hi scubaaronh
when the buoy is inflated from 5-6m (15-18ft) and released, the restrictor and the weight of the Brass Snap Hook (on the WDS) and the weight of the Stainless Steel Ring will always keep the open end of the buoy far enough underwater to ensure that air does not spill from the unit and deflate.
- The Surface Marker Buoy does not have a one way flap;(duck bill valve set up) there is a throat or restrictor at the bottom end to channel the air into the buoy. The buoy and Webbing Deployment System (WDS) have been designed in such a manner that:
on the surface, once the WDS has been secured with the Bungy, you can let go of the whole unit with out worrying about the unit deflating (there is enough weight on the whole WDS to ensure that air does not spill from the buoy even in a swell.
Note: The Surface Marker Buoy WDS was designed for recreational divers doing safety stops and was not designed for technical decompression divers.
- Therefore there is no need for an OPV (Over Pressure Valve). By eliminating the need for and OPV the unit is much more compact and easier stow as well as being able to fully deflate the unit in a matter of seconds for stowage.
For further information please dont hesitate to contact me.
