Udo Hartig:Hi WetFatCat,
I think we have what you are looking for.
A product specifically designed to be deployed by recreational divers on their Safety Stop.

The Webbing Deployment System is easy to use and greatly reduces your risk of entanglement as it does not need to be unraveled before deployment.
The disadvantages of the string /cord method are that you need to unravel the full length of the cord (or let it drop free with the weight of the bolt snap). This can only be done if there is nothing below (i.e. Reef) and also increases the risk of the line or cord snagging on equipment as your SMB shoots to the surface. A reel or spool is a better option than the cord in this situation. The WDS eliminates the need for a reel or a spool just for sending up your Surface Marker Buoy.
I have my doubts about semi-permeable fabric buoys mentioned if these buoys are letting air through, what keeps them inflated at the surface.With all due respect to DandyDon, yes I have seen many of the fully closed oral inflates explode it is only a matter of time + depth + too much air before they fail. They are great for on the surface and as a back up sausage.
- Worst case scenario you are out there for several hours +, and your buoy is constantly leaking
- Is there really enough air coming out of the semi permeable fabric to prevent it from bursting when sent up from 30m / 100ft (look at the size of and OPV on BCD or Tech buoy it is there for a good reason)
I can see how this system would be beneficial to many divers. But the diver in the video has that bungee around the wrist. If an unsuspecting (or just blatantly ignorant) powered boat comes along and snags the SMB, that divers can get hurt badly.
But again, I can see how this would make life easier for many divers who can not/don't want to work a spool.
