I’ve stayed away from reading this thread, but I need to provide some prospective to @BLACKCRUSADER statements on BSAC training. Some of the things he claims to be BSAC training were provided by his instructor, additional to the Sports Diver (SD) syllabus.
In the 1980s when he said he was trained, Nitrox was not in the syllabus. Even today a newly minted SD has to undertake additional training to reach 35m or to use gasses greater than 36% O2. Diving below 35m as a SD requires Trimix training, see here.
Thank you Edward3c All these changes for the better. Question, do the new standards mean the older standards divers were taught under no longer apply? No more deco air dives at 40m with deco stops ( ps we always had steel 120 with 230 bar or around 3500 liters of air in tank and other tanks on the shot line at depth as well. )
Again this thread has veered of from just getting nitrox certified to deco and technical dives and what not which Dody has no intention of doing. Nitrox use is better for dives where you can get longer times to NDL and better over multiple dives in several days or more of diving. As he dives with his wife they can get the benefit from that. I've not always used it as my dives are at vacation resorts and often that is shallower than a lot of vacationers dive and also do not exceed NDL. Some of my vacations are diving with friends who are instructor level as well as TDI Advanced Nitrox Decompression certified some with other tec certs.
Most dive centers don't want DM's doing deco dives as they are there to take out the vacation divers. Some dive centers will let you do deco dives with an appropriate DM or instructor but usually has to be arranged in advance.
So Dody is the multilevel diver staying within NDL limits and probably dive times of an hour more or less. Pretty much how I dive now. I may do more dives on nitrox with 32% setting rather than 21% setting as I also tend to do. I don't always need the longer NDL times and sometimes you are in a mixed group where some are on nitrox and some on air. If I get an instabuddy using Nitrox I switch to Nitrox.
