PADI Deep?

[MATTBIN]

Ok lets take this one away from Diggers post.
Lets assume for the moment I have a few (60) dives under my belt, in the range of 25/30m both here and abroad, Sea and Inland, cold and warm, poor and good viz. So I think I'm experienced but not super cocky or blase about the dangers. I'd like to dive a BIT deeper, location UK but my life policy says no to any non-certified diving so I'm stuffed. I know I'll do a padi deep course, I already dive with a pony non deco so its a minor step up (down?) to go to 35m in the RIGHT conditions on the RIGHT site. Maybe Sacpa, maybe not, Scapa was just the first example I could think of.


I dont want to go twin tanks, I dont want to go into any deco diving either. I know this will restrict my bottom time but I can live with that at present.

Where's the problem? I'll pick this up when I get home as I'm in the office now and I'm off home soon.

Marks being a little facetious (because that course is unavailable in the UK at the moment) but that course would indeed cover not only nitrox but trimix for recreational diving up to about 37 mtrs.

From your post I do not see the benefit of doing a course such as PADI Deep Air Diver. I'm a BSAC diver and as sports diver can dive to 35m and as Dive Leader can dive to 50m on air.

The depths probably aren't as much of an issue as the gas you are breathing. 30m NDL 20 mins, 35 NDL 15 mins, 40 NDL 10 mins. (Buhlmann 30/90 Tables)

If you were doing a wreck dive and using a reel to tie in from the shot by the time you've tied in its nearly time to ascend.

What I propose is that if you looked around at other courses such as perhaps an advanced nitrox then you may be able to do the dives you want to do under that C Card and gain a real benefit in your diving, thats all.

<font color='#0000FF'>Matt, if you did your BSAC Sports Diver that would qualify you to 35M, or the TDI Nitrox course would give you far more &quot;depth allowance&quot; than you actually need (45M)

Matt, looks like BSAC SportDiver would be the way to go.  I'm doing the  Dive Leader stuff now but I wouldn't really want to be doing 50m dives on air - not in the cold dark conditions in the UK anyway - I'm aiming to do Normoxic Trimix for that sometime next year.  You don't have to join a club to do it - you could goto a BSAC school and get the qual.  Although not sure if you can get there directly as a PADI cross-over from O/W or AOW and also don't know if this means you would have to join BSAC (and maintain it to keep your qual).

I must say I didn't view the Nitrox course as allowing me to progress my depth qualifications.  What do I mean by that?  Simply that as a BSAC SD I can dive to 35m but I wouldn't then use the Nitrox course as justification to goto 45m - i use it simply to use any combo of Nitrox to 35m.  Am I a slave to BSAC here? - I don't think so - just being sensible.


***edit
Actually thinking about it try SDI they have a deep diver course, I think Ben did this. &nbsp;You can do this with Andy Dalesdiver - give him a call - he will be able to give you chapter and verse.

<font color='#000F22'>Matt,

I'd do a few more dives and particularly sea dives before thinking about deeper sea dives. I certainly do not doubt your ability and I'm sure you're very sensible.

BSAC Sport Diver would be a good idea as it includes rescue skills - something that as an AOW you haven't covered formally.

Rescue skills need to include self-rescue as in UK conditions - and poor viz depth presents it's own challenges.

Looking forward to getting out on a sea dive with you at some point.

A few years ago when I did my AOW I had to go to 40m in Dotty to pass the course. My understanding was that as an AOW diver I could dive to 40m. As a DM (non working) I understood the max depth under PADI was 40m - have I got this wrong

Have since got the Nitrox card (to 40%) but cant remember this allowing me to go deeper.

Any practicing Instructers out there who can clarify ??

To add to the debate, I agree with the `if you want to go deeper - get some training` philosophy.

<font color='#000080'>Sorry to hijack another thread, but I personally don't see the problem with deeper air diving. Most of the guys who are doing it know what they're doing, and know they're narked.

I don't get any noticable narcosis until about 45, and even then it's not suficient to be an issue. I can still do drills just fine, and have done sums and all that just to prove it. My times were barely different, and I was writing underwater.

I allow for narcosis, cold, and all the rest of it when I dive deep air, and I don't have a problem. I'm playing with trimix soon on dives that I would normally use air for, and then maybe I will be in a better position to judge, but right now I'm happy diving air.

I don't have a problem with PADI's 40m limit, but I do think (from what I understand will be n the course) that more emphasis is going to be needed on equipment considerations. My regular buddy's on the course, too, and he's a PADI AOW and BSAC Sports. Then again, he's already thought long and hard about his twins rig, and we talk specifics a lot anyway.

The course will essentially be a formality for me, I'm certain, but I want the ticket for teaching in the future. Besides, it's costing me about £20!!!

AFAIUI , Padi AOW depth limit is 30m, but I'm BSAC so will stand to be corrected.

As for deep air diving, I'm more cautious than Digger, but I think that's an age/experience thing. A few years ago I would have gone to 40m on a 12L plus a pony, now I'd want twins and 100% O2 for deco

First time I did 30 m was on a 200bar 10L with an old Spiro reg, which now I wouldn't trust on a pony as a back-up, back when I was BSAC Novice 2 diver (or as we used to say &quot;Nervous diver&quot;, &nbsp;works better with the Northern accent)

I've found that the more I progress in diving (and generally grow older?) the more cautious I get. e.g. I wouldn't get another road racer and bomb down the A19 at 140mph, didn't have speed cameras when I were a lad  

Personally, I'm not much of a 'depth fiend' but &quot;horses for courses&quot; and all that

Digger,

if its only 20squids, you already know the limitations and gets you further along your path then bloody well go for it. &nbsp;But you've already decided that anyway.



As for training, any course will just be lots of Nitrogen / Narcosis / Deco theory (which is nice) and then a dive or two to the max depth (or there abouts) for the course. &nbsp;BSAC do the depth progression in stages but still (for Dive Leader) allows a dive to 40m one day and then 50m the next and then that's it you're ready to dive to 50m on air - (showing all proper dive planning also) - this bit ain't exactly rocket science. &nbsp;

Whats important is lots of getting used to the depths and the feeling / impact of Narcosis which is where things can go really FUBAR if you're not expecting / used to it. &nbsp;Even if doing a quick course (no names mentioned) then it's probably still worth re-doing this 'acclimisation' &nbsp;and build-up the depth experience.

All of course IMVHO.

And Matt, under the conditions / proviso's / Limitations that you've stated, and returning to the original question in the thread, I don't see a problem but you're Insurance co might. &nbsp;If you do progress your depth quals and your Insurance covers it then there's abs no probs.

done both the padi and bsac courses

aow padi was to 40m but they recomend 35m max (12 months ago at least)
bsac sports is to 35 and dive leader to 50, you can dive to 50 as a sports diver if you are in training for dive leader

your nitrox courses will give you 1.5barr ppo2 at 40m and a bit less nark on a 30%mix, this can only help, oh and a couple more mins bottom time

just a little thaught, going back about 4 years
&nbsp; &nbsp;i had done the 40m boy a doty a couple of times, done the 35m box at stony i had about 40 dives under my belt, we went &nbsp;on a hardboat out of angelsey (johns illusion) to do a 43m dive, got down there to find i had lost my buddy, it was pitch black, and with my tourch i had 1m viz, i shite myself (there was more because i got stuck but thats another story)

in my log book i wrote something like,
43m deep no budy total black, no viz, is fookin serious diving, and not to be taken lightley, lern from this or next time you might not come back

now im not trying to put you off, and some of my best diving i have done has ben in the 35-55 range, but the english sea can be a bitch, and needs respect, so try to build up your experiance
