Automatic diver recovery system

However, if you are that worried about someone being able to find your body may I suggest you stop diving.

Let me reiterate that my original thinking along this line with Steve was simply that I couldn't cope with the idea of two perfectly good Megs disappearing into the blue. So my idea was of an "Automatic DIVEGEAR Retrieval System" and has been misconstrued in this thread. I didn't care what the two Megs in question were actually attached to.

No one would want Steve's body anyway; it's completely ****ed already. Just ask him.

I can feel some shiatsu coming on...shall I open the beer?

Just had a thought

Has anyone come up with ---- emergency surface marker buoy
fitted with a personal Epirb that emits the radio distress signal for a day , just like we have in our boats. Can be tracked by aircraft or base stations as long it is attached to the diver or the gear.

in theory an automatic diver recovery system is a nice idea. but practically quite complex due to the nature of different dives like cave, wreck open sea, etc...
personally a kiss style inflation on the wing would make me feel uncomfortable. positive buoancy may in some cases not be of advantage if s... hits the fan.
equipment for faster recovery and/or identification is presently i think best.
in most cases if in an accident a search is conducted and devices for fast finding are best.
i use a red mini strobe during dives together with bright white equipment colors. both give good and fast easy identification. i dont see any reason to dive in black or dark blue equipment except if u wanna be in a military stealth style operation.
there are mini epirbs for divers on the market and it may seem a reasonable device. following daily diver news from around the world it is astonishing how many divers get lost at sea upon surfacing. there is nearly such an incident every week.
in general at present i think the best is to help and increase a speedy finding regardless if being in an alive or death condition.

All the p*ss taking to one side there is scope somewhere in this thread for a serious idea....

I have been wondering for a while now about a transponder diver locations system for dive boats that would work in a similar way to the avalanche search systems mountain rescue use. (Tradename Recco I think?)

First idea would simply be to find missing divers using a passive transponder stuck to their kit, like an underwater radar deflector if you will...

That got me thinking about an active system the diver could operate if they got into difficult and would guide the dive boat/searching rescue diver to them like the Neverlost System from Aladdin? (Like an underwater EPIRB)

For extreme diving the best system I can think of would be a combination- a small transponder carried by each diver off the boat and monitored thoughout the dive by sensors on the boat, each transponder would have a different frequency or "callsign" so the skipper can see who is where and the transponder sends back its depth so the skipper can see who is not following the aforementioned dive plan, still on the bottom after 30minutes? then he can call the coastgaurd/put in the safety diver and can start the rescue/send for help before even the DSMB count comes up short.

(On a deep gas dive that means starting the rescue something like 30minutes or an hour earlier!)

This system should include a SOS button the diver could push to bring the boat and rescuers to them.

I don't really have the time and skills to work such a system out but if anyone does think they could make a 12 channel transponder system and a location triangulating sensor grid that would fit on the bottom of a small hardboat and not be mega-bucks then I think there is a market- certainly in the Red Sea and Austraila where they seem to leave divers behind all the time and in the UK where we often can't find our "fallen" comrades. While I agree that many of them wouldn't want to be found.... when someone is lost its not really all about them anymore.... some families don't like to bury an empty coffin

Just my 2p's worth.

Apologies if its already been suggested.

A small device emmiting a sonic beacon could be a good way to go. It might take a bit of work for triangulation from the surface but it should get the job done. The unit could probably be produced to be the same size as a strobe. Also it doesn't have to be in the human acoustic range (or may be timed to go off when you're dead) so people needn't start moaning about a silent world etc etc.

Seeing as sound travels better in water then it could probably be located from a fair distance away!

Fair cop. I have well and truly left my Manpower days behind

Lets say one were to be diving with a Multi Meg, twin colour VPM VR3s, assorted other diving finery and a hungry family of Noahs. After the Noahs had had their way with you it would be great if your mates could get some use out of the thousands of dollars you have strapped to your person. Leaving the body behind would be handy because it would be creepy to inherit some gear and find a piece of the orriginal owner in the counterlung. I mean that would be just weird

I think we might want to have a look at these folks.
http://www.desertstar.com

They seem to have most of the bases covered.

Desert Star has some innovative products!

Ben Field · 1st December 2005, 09:46

I assume this was the URL that we where meant to find-
http://www.desertstar.com/newsite/sport/sportscout.html

Certainly seems to cover most everything I suggested ealier... okay its not Very cheap but its not overly expensive (about the same as an EPIRB) and I'd much rather be found quickly by my boat than have to wait for a coastguard chopper to find me and whisk me to the pot!

The Sport model looks just the ticket... even looks tought enough to survive diving off a UK hardboat!!
