Could it mean deployed?

hunter991:
No Brent, all that I have read specifically talk about "DELAYED"
Edit: They talk about deploying a delayed SMB
Could you provide a reference?
AP Diving/Valves has one that I've heard called a delayed SMB.
What they have is an SMB with a small tank, size of a coke can, attached. You unroll the SMB, attach your reel and open the tank and let her go. The SMB inflates as it heads to the surface. There is an overpressure valve on it to keep it from popping/over inflating.

That might be it.

I thinks it just a marker that can be launched from depth marking your location underwater while decompressing or performing a safety stop especially effective in currents. Not sure where the delayed part comes in though but have often heard of divers referring to them as a dsmb or a smb.
I thought the tank that inflates it makes it delayed - that is it is inflating as it is heading to the surface. Now I'm not so sure since I've seen a reference to a self inflating DSMB - http://www.bsac.org/techserv/irc/6dsmb.ppt.
They call it a SMB that inflates on the surface. I'm wondering how it gets to the surface if there is no inflation at all? Must have some positive buoyancy. Makes sense if there is some kind of switch - it doesn't generate enough lift to pull you up until it is on the surface. Could be safer.
Maybe they call it delayed since it is taking us so much time to figure it out.

I think it's simply what we call a safety sausage/smb. A normal smb is presumably one that remains on the surface from the beginning and you tow around during a dive to let people know there are divers below. A 'delayed' smb is simply one you keep in your pocket until the end of the dive thus 'delaying' when you use it.
That's my take anyway.....
