Your not getting it. At the time the Air 2 was developed there was no reliable way of holding the octo in place. All you had was those stupid holders that you stuffed a mouthpiece into, that only worked reasonably well with certain types of mouthpieces. Why should a diver need to continually keep reattaching the octo to the holder?
Why? Because that's where it's supposed to be to reach in an emergency... Furthermore, how octo holders functioned in the past is irrelevant. How they function now is all that is relevant. I personally have absolutely no problems whatsoever keeping my separate octo in the proper place. Why does everyone else have so much trouble doing this, when me, the new diver who is apparently inexperienced, has no trouble at all? That's doesn't make any sense to me. It's extraordinarily easy to keep my octo in the proper place. I don't understand why people think this is so difficult. It's not difficult at all...
At 0-24 dives, you are a new diver. As time goes on and you get more experience you will find that equipment failures are rarely out of the blue. Usually the gear gives some sort of indication that a failure is coming. However, you may have to look for it.
I may be a new diver but I'm not stupid. I'm an accomplished engineer. Also, I'm not talking about the probability of my buddy's regulator failing. I'm talking about the probability of my regulator failure. Mathematics proves, without any doubt whatsoever, that a separate system is more reliable with regards to failures. It's not a matter of opinion, it's a mathematical proof. If you want to argue against mathematical proofs, yea, I guess you can do that if you want...
You really don't have a point. Your gear is completely independent from your buddies so if your inflator malfunctions it does not affect the probability of his regulator failing.
Just because you are making my point into a strawman, doesn't mean I don't have a point. My point has nothing to do with my buddies regulators to begin with.
SB is full of people that like to come up with what ifs. It is usual protocol to call a dive in the event of an equipment failure, so loss of the octo doesn't mean anything.
It does when you are already underwater, which is the context of my comments. If you take my comments out of context, you then start making a strawman.
How many first stages do you use when diving? Most divers using single tanks only use one. If that malfunctions you lose everything.
How many first stages there are is irrelevant to anything I've said.

From
DIR-Diver:
If we have a problem we donate the only regulator we KNOW is working - the one we are breathing. That way we also know that we give away something that is safe to breath at that depth - important when you use multiple gases.
After donating our regulator we need something else to breath - our backup regulator. Since our backup is what we are going to use in an emergency we need to find it fast and we need to be sure that it is going to be there. Let's see how we can do that.
I do not have the fundies book handy but I believe it says something similar. As I mentioned before the Air 2 and DIR/Hog setup share a similar philosophy. Certainly in an emergency you know where your inflator is you know it is going to be there.
And that is precisely why not keeping your octo in the proper place where it should be, is a "poor diving skill" to begin with. Why, because you need to find it fast in an emergency... Like I said before, me, the new diver, has absolutely no problem doing this. It's not even an issue...But apparently other people have issues doing this very simple skill of keeping their octo in the proper place...Why do they so much trouble doing this very simple skill? Hmm, good question!
