    Well, I do always have fun. :eyebrow:

    The signal to noise ratio on ScubaBoard is about the best I have seen on any forum. When myths and otherwise bad info is dealt out, ScubaBoardians are pretty darn quick to point that out. Any reasonable person can discern the silver from the dross here and most of the resistance seems to come from self proclaimed experts that are not happy that such information is so readily available. In the not too distant past local dive shops controlled the knowledge and profited from that. Today, the paradigm has changed significantly to benefit the consumer in regards to knowledge acquisition. The smart dive professional has adjusted to this shift and has actually used it to make his classes even better. Some talk about the instructor who has gone the "extra mile" and frankly: we don't see that as an "extra" but as essential for us to continue and thrive. Teaching to the minimum is no longer tolerable for most of us and we expect more from ourselves and our students. This is great for everyone except those stuck in yesteryear.

    Blue Sparkle...and so is life. If we were always in agreement, it would sure be a very boring life with no improvement, advancement, etc. In retrospect, I can honestly say that I have nothing negative to say about the dive instruction that I have had. I am glad I got the very rigorous OW NAUI course I had in 78 that so many folks nowadays seem to be in disagreement with. And then I was very lucky to meet awesome and very demanding instructors along the way who all strode to teach beyond the minimum standards and thus allowing me access to additional litterature and knowledge to further progress.

    Yes there is the occasional noise on the forum but if one looks beyond that there is a wealth of information as well. I think it is important to be exposed to more than one point of view because you can use that to challenge your instructor wrt to some of his ism or preferences.

    I agree, Scubaboard is a great resource. You do have to be careful at taking the first thing you read as 100% true, but if you wait a bit someone usually comes along and tells you how that post was wrong...repeat cycle... :) Overtime, you can learn a lot on this site and get connected with those who can teach you even more!

    DevonDiver you are correct the knowledge reviews can be done on the boat but really can you go over the information with the boat engine going and the other divers talking and setting up there gear and also try to finish up before the dive briefing. You could do it on a liveaboard but a day boat would be hard.

    It depends on the boat and the location, I guess. That's why PADI haven't made it a 'standard'... it gives the flexibility to those who can.

    Depends on your instructor. In general, I would say 130 feet with air is dangerous. There is a real chance of narc. I used to think I can use air and go even deeper. There is a site I dive often at max depth of 120 depth. I dove there many times and thought I know it inside out. I dove the same site after getting trimix cert, things were certainly different than I remember. I am still alive, but I do know the effect of narc. I won't dive that deep with air anymore.

    On a training dive, within recreational limits, I think that experiencing narc is one of the learning objectives. The trouble is, most students expect narcosis to be some sort of obviously debilitating 'drunkenness'. When that doesn't happen, they think they aren't narc'd.

    I've often thought about the relative benefits of taking down a stage of trimix... and then letting students breath some much lower END gas during a deep dive. When their heads clear because of the helium, then they'd have a great demonstration of how narc was affecting them.

    Not sure PADI would ever allow this though.... :(

    Not to hijack the thread, but your MOD with an FO2 of .28 should be somewhere around 130-135, not 150.

    Lucky you didn't do the funky chicken down there?

    That is why I said depends on the instructor. Experiencing a slight narc under close supervision is fine. The key is the one who is supervising need 1) not to be narc, so that 2)aware of student's state at all time. The only way the instructor(s)/DM(s) stay clear of narc is if they are on trimix. And to be safe, you really need 1:1 student/supervisor ratio here. I have seen way too many PADI instructors doing this kind of deep dive in a unsafe way, at least to my standard.

    I've heard it's even more noticible if you go down breathing trimix and then switch to a nitrox mix at depth.
