I was misplaced on a drift dive a few years ago with 7 other divers, all
experienced but none carrying any type of signaling device (apart from one
pair of light green fins, slates and those plastic whistles on your BC, I
had a cylume stick).  I wrote about the whole thing in Sport Diving at the
beginning  of last year (for Aust. divers) and the rescue made it onto the
channel 9 news (first item, must have been a slow news day :).  We were
eventually found by Air-sea rescue after drifting about 10 nautical miles
in the East Australia current.  Rather than going into detail here if you
are interested I can email you a copy of the article I wrote, rather long
I'm amazed Sport Diving published it!!

Anyway now I carry a safety sausage on all dives and usually a cylume stick
and torch.  In the article I talked about some options for signaling
devices and have since had discussions with people on either this list or
SCUBA-L (I can't remember which) on the topic, I've also recieved material
and comments from people who read my article.  Flares, whistles, EPIRB type
beakons have been mentioned already on this thread.  From memory the
beacons I have read about (namely the SEA-MARSHALL personal locator beacon,
UK) have limited range and are probably unsuitable for instigating a search
(insufficient signal strength to bounce a signal off the sattelite) they
can, however, be located by searching aircraft from a reasonable distance.
As long as people know you are lost everything is fine.

Something that hasn't been mentioned sofar is floating flourescent dyes
(such as SEAMARK by Paynes Wessix, Aus.) which mark your position with a
brightly coloured slick on the surface of the water. This only lasts for a
short time so obviously you would want to release the dye when an aircraft
was near-by.

Hope this helps,

Simon
