View Full Version : question for ssac divers/instructors
A guy at my work is a ssac sport diver with around 20-30 dives,i was chatting with him yesterday and he was telling me he's doing his master diver award.
He reckons he can do deco diving on a single cylinder using only air with his suunto after he's completed this award :eek: as he's currently doing his "advanced decompression lectures"??? :confused:
Surely this isn't right,after speaking to him yesterday it was obvious he hasn't a clue :thumbdown: and even this early in his diving career he's already spent a night in the pot :eek:
Scary :(
You need a minimum of 70 dives to get the master diver award, so although he can work on doing his master diver skills just now, he won't qualify until he has at least 70 dives.
In my opinion, SSAC are rather quiet on what they allow decompression wise. While their depth limit recommendations are very clear and are published quite widely, I do not think that they are clear about deco.
My understanding is that Sport Divers are not meant to 'plan' deco, but that master divers can. That of course then raises the question of what kit a master diver should be using if they do plan deco.
Personally, I would not plan any deco on a single cylinder and in training other divers would make this very clear. However, I would not have a problem with doing a few minutes (max. say 5) deco on a single with a pony. Any more than that, and it's twins.
He probably is doing lectures that are called 'advanced decompression'. SSAC has decompression lectures at Sport diver level and you have to be able to work out deco requirements for repetitive square profile dives from Buhlmann to pass the Sport Diver exam. That doesn't mean you should be planning deco dives however - it's more just you need to know the theory. The further lectures at master diver level are more in depth on deco, which I guess is why they are called 'advanced deco'.
On another point, although the minimum no. of dives for master diver is 70, I don't know anyone that has achieved it this quickly, mainly because there are a lot of assessments and unless you get an instructor out training with you every weekend it will take a while.
I did my first master diver assessment in August 2004 and it took me until last September to finish - some 200 odd dives later. That was mainly because I just concentrated on getting experience diving.

Does not really surprise me.
BSAC Sports diver which you can in theory get after 9 dives gives you a deco ticket, which has no limit and whilst starts you off with a 20 meter limit, can build up to 35 meters.
The TDI one is even more advanced, 25 dives and you can use 100% 02 and do accelerated decompression with no limit.
TDI Advanced Nitrox Diver
This two day course, includes 4 nitrox dives (100 minutes bottom time) and covers all the topics in the nitrox course in much greater detail, with in-depth coverage of CNS & whole body oxygen toxicity and tracking, common mixing methods, best mix computations, decompression gas, accelerated decompression, dive planning, gas consumption calculations and equipment considerations, all culminating in certification to use 22% - 100% (oxygen) as a breathing gas.
Includes: TDI Advanced Nitrox manual & certification
Pre-requisites: Nitrox diver or equivalent, 25 logged dives, minimum 15 years of age.
The reality is that people rarely do the bare mimimum although there is always the odd one who does. If it was such an issue the agencies would look at changing it.
I used to know a lad who had a 100 meter trimix cert and had done 120 dives......:eek:

In fact ITDA after 25 dives will allow to do their Decompression Nitrox course which is a 40 meter depth limit using upto 60% mix for accelerated deco and max 20 mins deco. Thats a lot for a PADI Rescue diver to learn.
In regards a few minutes of deco on a pony, its not something I would choose to do, however it happens loads of times and people seem to survive doing it.
Anyone ever been into deco in the red sea on a single? :p
It's 60 dives for Master Diver (according to ScotSAC website). I know people who have hundreds of logged dives each but still don't have Master Diver qual. This isn't something that's just handed out willy-nilly and I doubt if any BDO would ever consider signing someone off as Master Diver with only 60 dives in their book. A student can take the lectures (as this increases diving knowledge therefore making them (in theory) safer divers) with very few dives under their belt, but will not be permitted to undertake open water Master Diver training until sufficient experience has been gained. I know of Sport Diver trainees who are permitted to attend Master Diver lectures. This doesn't mean they are being fast-tracked through the (excellent) ScotSAC training system, just that they have the intellectual capacity to take the increased knowledge on-board.
ScotSAC are, in my opinion, very clear about deco. They do not offer any decompression diving training/courses or quals. If a ScotSAC member wants to venture into this area he/she must train with another agency. Therefore there are no decompression diving components in any of the open water training evolutions required to achieve Master Diver. The ScotSAC Master Diver lecture (No.3) titled “Advanced Decompression” is NOT intended to teach decompression diving skills/techniques, but to equip students with more in-depth knowledge of the science behind DCS, diving physiology, nitrogen absorption, neurological tests etc than those taught at Sport Diver level as this would be information overload for some brand new divers.
So far as number of dives = better diver goes, this sadly is not always the case. I recently had a very close call with a so called "experienced" diver (I won't bore you all with the details but I still don't know how neither of us got a bend :confused:). I'd much rather dive with someone who had 50 dives and was good than someone who has 500 and isn't.
Sounds to me like you’ve maybe mis-understood what your mate said Loudy? I reckon he's doing the lectures but will not actually start in-water Master Diver training and assessments for some time.
Actually, it is 70 dives. The Scotsac website says:-
At least sixty properly witnessed and varied dives of submerged duration of not less than 15 minutes each. Total dive time to exceed 30 hours logged underwater. (In addition to the ten dives logged for Sport Diver qualification)
30 to a depth range between 9 - 20 metres
20 to a depth range between 21 -30 metres
10 to a depth of 31 m or more, implementing NDC Deep Diving Regulations.
(The ten dives for Diver qualification shall not be included in these sixty dives.)
60 in addition to the 10 logged for Sport Diver. 60 + 10 = 70. :rolleyes:
It would be very unusual to obtain a Master diver qualification with only 70 dives, but if the person has fulfilled all the requirements, I don't think it would be fair to not sign it off just because he or she has only done 70 dives.
Divebuoy, you say that Scotsac do not offer any decompression diving/training or qualifications. Are you confusing this with accelerated decompression?
They offer a Deep Diving course that qualifies you to 50m on air. It specifically sayd on their website that the course does not include accelerated decompression but that the use of air or nitrox is acceptable as a back gas and as a decompression gas by suitably qualified divers.
Sounds to me like you’ve maybe mis-understood what your mate said Loudy?
No i didn't misunderstand him as he say's he's done deco already :rolleyes:
This is the same guy who said he hates helping lift folk's gear who use nitrox as those wee bottles (pony bottle) of nitrox make their gear so much heavier to lift :rolleyes::eek:

If Scotsac are signing these people of as divers they seriously need to reveiw their qualifying standard, or in his case maybe just shoot them:D
ScotSAC are, in my opinion, very clear about deco. They do not offer any decompression diving training/courses or quals.
I've just noticed where you live divebuoy,i'm pretty sure he's a member of your club :eek:
All this talk about how many dives etc wasn't the question,this was what i was meaning.
Actually I think we're both wrong :o
Main training page of ScotSAC website says "Sport divers with more than 75 logged dives can work towards the Master Diver Award which provides for increased technical knowledge and deeper dives up to 40m."
I wasn't trying to be a smart alec just pointing out that despite only needing 60 or 70 or 75 or whatever logged dives, no self respecting BDO would sign a diver off at this level with that amount of experience. It would be totally irresponsible. The person therefore could not fulfill all the requirements because they just simply wouldn't be allowed to undertake the training until they were deemed suitable by their BDO. So saying it would be unfair not to sign them off is probably hypothetical and should never happen in reality.
The statement I made about no-deco diving and ScotSAC was I'm afraid just me paraphrasing what someone else told me. Another lesson for me to check before I post ;) I'm fairly sure though that the point I was trying to make about Master Diver being a no-deco qual is still true?
If Scotsac are signing these people of as divers they seriously need to reveiw their qualifying standard, or in his case maybe just shoot them:D
As I said in my last post, I suspect the guy is just doing the lectures and won't start in-water training or be signed off for some time.
I've trained with other organisations and my experience is that ScotSAC are very good. I think it's unfair to tar the whole organisation with this brush due to one guy's opinion of what a pal at work meant/said. I've dived recently with a guy from another agency too and how he got signed off I'll never know!!
Scotsac are in the process of changing their training structure and I think the 75 dive thing for master diver is part of the change - someone has obviously got carried away and posted it before the training syllabus is fully implemented.
I disagree though that a person with 75 dives should not, on any occasion, be signed off as a master diver. Compare this with the 60 (I think) dives required to be a PADI divemaster. While in practice, I'm sure most divemasters have loads more dives than this, the standard is set at that and it would be unfair to not sign someone off merely for only just meeting the standard.
I don't agree with the statement that the master diver qualification is a no deco qualification. It certainly does not teach accelerated deco, but as far as I'm aware, it allows for planned deco dives.
I also don't think there's any harm in starting master diver training once you qualify as a Sport Diver. I had a Sport Diver out for some master diver training last week - launching a DSMB (actually about to be moved to SD syllabus) and she has just qualified as a sport diver, although she was Padi advanced before that. Anyway, she did a perfect DSMB launch by herself.
It's 60 Dives before you can start the PADI DM course is it not?

I thought it was 20 to start.
PADI is a commercial operation where instructors make £ from divers who are paying for their instruction/quals. I'm sure the PADI organisation wouldn't last too long if, after taking the ££, they then said sorry we're not giving you the qual. I know when I did my PADI AOW I was far from being "advanced" (and still am :D) but got the card anyway. Did this make me a better/safer diver?? I'm sure the training is different for each too and there will be elements in the ScotSAC training that are not included with PADI Divemaster? Therefore I don't think it's a fair comparison and, IMHO, certainly doesn't make it right (just my opinion ;)).
Extending your argument about MD and deco a bit further then does that mean Sport Divers are deco trained because they learn about stops at 9m, 6m, 3m etc from Buhlmann tables?
For my own education (and God knows I need it :001_smile:) Are there any training evolutions for MD that involve a decompression dive?
I thought it was 20 to start.
God your right, that's crazy! So with a total 80 dives you could be a DM. Suppose it's designed for those that want to go and work in the resort diving side

It's 60 Dives before you can start the PADI DM course is it not?
Don't think there is a minimum to start, just 60 dives before qualifying and, of course you need to have done AOW and Diver Rescue first so you are unlikely to have less than 20 when you start.
Many PADI DMs in the holiday resorts gain their qualifications as Interns working their way through the PADI system and may well have gone straight from OW (4dives) to AOW (10 dives) to Rescue Diver and on to DM Trainee in 2 or 3 weeks. It sounds scarey to those of us who have come up through a club system but the hours they put in are probably well in excess of those outr trainees are given with a typical club having one hour of pool time per week.
There are obviously Pros and Cons to every system and I would certainly trust one of our (SAA) Club Divers before a newly qualified PADI AOW with 2 weeks experience but, like any divers, experience counts for more than qualifications and the important thing is not what you did to get the card, it is what you do afterwards to build up your experience.
Probably the biggest benefit of diving with Conger Alley is the chance to see so many different agencies and styles. I've seen divers from most agencies and can honestly say that I have never found any branch particularly better, or worse than any other.
I've met divers from every corner I would happily trust my life to. Equally, I've met numpties from them all I wouldn't get close to in the water. (And I'm sure there are a few out there who are thinking "isn't that the ar5ehole I dived with?":p)
Most of the people I dive with fall somewhere in the middle. I am happy to dive with them because I don't think they will get me into trouble but I take responsibility for my own safety and do not trust my life exclusively to the Buddy system.
Are there any training evolutions for MD that involve a decompression dive?
This was my original question :confused::confused:

That is a pile of crap :(,to pass the padi course's you must meet the performance requirements!!
You won't fail but you won't pass until you meet the requirements.

OH Don't get me started on that one. :thumbdown: Been there, tried that, got ignored, then lectured at by someone with about a 10th of the diving experience of myself and about a 20th of the guy I was with(who by the way just happened to have trained some of the folk that ended up training these 'experts'), but that was in the days of the old regime. Perhaps things have changed.

Yup, don't get me started either :vmad: I remember that fiasco of a meeting, they spoke emphatically with ignorance :D
Back to basic's here as i'm confused with all these replies
1.can you do decompression diving as a ssac diver?
2.do ssac do a adv nitrox course or even a basic nitrox course?

It's 60 Dives before you can start the PADI DM course is it not?
60 till you can qualify

Your not paying for your your certification with padi, your paying to be taught by a professional who instructional skills and materials are usually a hell of alot better then anyone elses, also a very large percentage of PADI instructors dont pay for their certification they do whats called an Internship where they work in a resort and gain experience and learn the padi system and work their way through it untill they are ready to sit their IE

lol Im glad you noticed, back up timers Great just aswell I can count a stop in my head eh:D
Back to basic's here as i'm confused with all these replies
1.can you do decompression diving as a ssac diver?
2.do ssac do a adv nitrox course or even a basic nitrox course?
My view on this is:-
1. Yes
2. No - not at the moment anyway. I think they've tried to bring in a basic nitrox course, but have struggled with instructors - something about getting them qualified then the instructors nipping off and doing it professionally. They do run nitrox courses, but they are taught by another agency. You need a nitrox ticket to get first class.
My view on this is:-
Fair enough being your view but would someones life insurance company take your view if they had an accident doing a deco dive????
S.F.T.R.D the way ahead :thumbup:
Fair enough being your view but would someones life insurance company take your view if they had an accident doing a deco dive????
Yes, I believe so. My view is what I have been taught within my club and is therefore within my qualifications. There is no Scotsac publication that I am aware of that says that master divers should not do deco.
Decompression theory is taught to a high level in master diver, and I think master divers are fully equipped with the knowledge to plan a deco dive.
Actually carrying out a decompression dive requiring mandatory stops is not part of the master diver syllabus. However, given Padi has removed the need to actually dive on the basic nitrox course, is actually carrying through a dive necessary for a qualification?

Claire there's a big difference between deco diving and nitrox diving!!
Padi also do trimix :D seems like ssac is behind the times,there's a lot better gases to dive with these days than air ;)

I'm well aware of the fact that there is a difference between nitrox and deco diving. My point was that there are many practical subjects that are taught on a theoritcal basis.
A club based training system is very very different to a commercial one. It's not a matter of do the theory, do a few dives then go off and dive by yourself. It's a gradual learning experience, with newly qualified divers being buddied up with more experienced divers every time we're out.
What do other agencies teach? I know Padi teaches no stop diving but how about BSAC/SSA etc?
PADI teaches everyting from try dive to ccr trimix
A padi DM and above get taught decompression theory but is not allowed to do it,what is the difference between padi and club training?? none that i can see.
The ssac diver at my work thought a tissue compartment was somewhere to store his hankies :rolleyes:
ps. padi do deco diving and trimix diving through their DSAT courses ;)

Isn't their techincal stuff under another name or something? It's all very well for an organisation that has hundreds of thousands of members to be able to offer so much training. Scotsac has around 1900 members and only a couple of paid members of staff. It's not easy for them to be able to teach things like nitrox and trimix. As I said, they arrange nitrox courses through other agencies.
Club systems can be a great place to learn and I think it's unfair of you to slate them because trainees are not being taught by 'professionals'.
We have a strict 1:1 ratio for instructors to trainees. There is no pressure on a trainee to qualify within a set period of time; therefore, they qualify when they are ready and fully confident.
Our basic qualification covers rescue training.
Finally, socially, a dive club is great and there's never a problem finding a buddy to go out.

Please do not judge SSAC divers by this muppet.
That would be like me judging all PADI divers by the ones I saw on holiday inflating their BCDs to ascend :eek:
So out of interest Loudy, had you done any decompression (even a minute) dives before you started training with Ian?

Behave children or you'll all go to bed without yer tea.:D
The main issue I have with the club system (I learned to dive in the club system) is that there are no standard training materials as with say PADI or ITDA :thumbup:. If you get a good diver who knows there stuff and is able to pass this on then your doing well. As training content is pretty much down to each individual club there are vast differences in standards and methods. I've spoken to guys who have been passed from one instructor to another every week and when they saw me training someone in towing techniques asked what I was doing as they never got this when they trained. This, along with most of the other stuff had been signed off without it being done. I even had one Instructor of many years experience telling folk during a lecture that it was safe to use air down to 80m :eek:. I put him right then left the club before someone died.
There are good Instructors and bad Instructors in every organisation. Having clear standard lecture material and a set training structure helps level the field. It frightens me at some of the crap thats been taught over the years. :rolleyes:

Well said MRF as always the voice of reason now get your name up on the atlantic divers trip so we can go bottle hunting :thumbup:
I guess we'll never know if deco is allowed in ssac or not so best a mod closes this thread me thinks ;)
SSAC do not recommend doing any decompression diving, so if this guy has been doing deco diving, then it could be the fault of his buddy. Many years ago, before pony cylinders and nitrox, we used to do deco dives on single cylinders with air because that was all that was available. Decompression theory has changed a lot since i started. We were told that if you were using air, you could dive to 80 mtrs before the O2 became toxic and that was only in the 80's, how times have changed :eek:
