PADI Deep?

Fatalities
The 2002 incident year started out looking as if it might become a very bad one for fatal incidents with 2 deaths in November 01 and 3 in December 01. When you consider that fatalities in December are quite unusual you will understand why, in January this year, we were predicting a gloomy outcome for the year. Fortunately this prediction did not come true, indeed the 2002 incident year has seen a significant improvement over previous years. When we closed the database at the end of September there had only been 14 fatal sports diving incidents in the UK. Of these only 4 were BSAC members. The high number of fatalities in the last quarter of 2001 has been more than offset by a reduced number of fatalities in 2002, with a total of 9 in the first three quarters of the year.

The causal factors behind the UK fatalities can be summarised as follows:-
Six cases involved depths greater than 50m. Two of these involved solo diving.
One involved a rebreather.
One involved a buoyant ascent from depth.

One case involved a diver who suffered a heart attack after becoming unwell in a swimming pool.
Three cases involved separation. In two of these cases the casualty was later found unconscious underwater.
Two cases involved divers panicking because of problems with mask and regulator.
One case related to a rapid ascent precipitated by a problem with a delayed SMB.
One case where there is simply insufficient information to be able to draw conclusions.

<font color='#000080'>Hi, &nbsp;yep sorry Lou, &nbsp;never actually checked to see what depth it would certificate you to. &nbsp;I picked up the 40m limit from an earlier reply.

I personnally found the Nitrox course very interesting, &nbsp;I did not get any benefit from the PADI Deep diver speciality. &nbsp;

Looking at the prices though, the Nitrox and adv nitrox still look like interesting courses for the money and I would rather pay a total of £250 for usefully training than £80 (or whatever the deep diver costs) just to meet an insurance requirement.

I am sure that there are instructors who would be willing to do a deal on the Nitrox and ADV Nitrox if done together.

Yes, Rob, I'm saying that i don't get narked at depths up to 40 m. See my posting on this subject on page 2 of the PADI Deep Dive Manual thread.

I know you may not entirely agree with that,it does'nt affect me greatly either but for the sake of this OK?).

I DO agree, Aaron! I always use EAN36 for my second dive, partly because it's safer but also because i feel less tired on nitrox.

<font color='#0000FF'>Yes there are, I did the IANTD advanced nitrox course in 97, the instructor just needed some proof I had dived to 40 meters on a few occasions before doing the drills as the course involved drills at this depth. I have continued to dive nitrox ever since and I try and dive on nothing but where depth allows.

I would recommed anyone to take a nitrox course, as I always dive this way I can't really comment on whether it makes you feel less tired after diving. &nbsp;

Why? My buddies all have their own bail-out. My pony is only supposed to get ME safely back to the surface.

Apologies John,I must have been at cross purposes,Doh!

Mark,
doesn't the concept of self sufficiency kick in here. What is the probability of both enjoying an OOG situation at the same time? We're not talking caves here.

[MATTBIN]

I use a pony, its for me if I suffer an OOA situation. If my buddy hits OOA instead of me he has his own redundant supply, or he should. If he doesnt, he can have my primary, I'll go to pony and WE abort the dive safely. If we both go primary OOA and only I have a pony call the coast guard or better still dont dive with him in the first place. He would definitely get my vote as a somebody I dont want to Buddy unless he is fully aware that if we both go OOA he's on his own.

Exactly! I would also point out that:
1. as a certain well-known Vic once said to me in an e-mail message, however much gas you take with you, it's not hard to visualise a situation where you might lose it all and you would probably drown;
2. if you look at the incident reports from different countries, you wil see that running out of air is in fact NOT a major cause of divers' deaths. Coroners' verdicts show that most divers whose bodies are recovered have plenty of gas left in their cylinders and their kit is usually in good order.
So let's keep this in proportion.
PS I also agree with every word Matt says on this.
