So in summary you choose to completely ignore the question as to why you have to have 2 stages under the left arm.
You're consistent because you then go on to fail to explain why you need to be able to check the SPG so frequently and without touching it. The only logical conclusion for that is a lack of appreciation of gas usage. Ie a lack of skills.
Then on post n:5 he ask if there is dangers in having the spg on the right. Thats why Ive answered that 1 of the reason to keep it on left is that the spg should be on the opposite post of which youre breathing (assuming youre diving twins), this way if your manifold or left post is close youll notice it.
You fail to address you'll notice it the other way too. You're either going to see gas being "used" twice as fast or not used at all. Again at this level you should have an appreciation of gas usage and the gauge is merely confirmation. If its not telling you what you expect then something is wrong.
So in my post the no other choice was to sum up all the different configuration to make it more convenient to check my spg.
But there is a choice. So you got that one wrong.
Or maybe that some agencies teach recreational diving with long hose and wings and other forbid them totally.
I can think of exactly 1 agency that bans a long hose. I cant think of ANY agency that bans wings. Enlighten is. What are these agencies?
Ive an OMS BC on my AL80 twins. This BC doesnt have a d-ring on the back of my
crotch strap
Why are you using a BCD with twins? Use the right tool for the job.
If you mean an OMS wing and plate then its a 5 second job to fit a d-ring. Again, right tool for the job.
(my other Hollis bc on my single tank has 1, now Im lost which 1 should I call to tell them theyre not approved practice), so that mean 2 stage clip and 1 spg clip and 1 leash clip have to be on my left d-ring.
And that's difficult how exactly? We're talking basic skills here.
I agree that I may have a language issue (English is not my 1st language) but its less choking than stating that you wont certify someone that has a different opinion than yours (your post n:82).
Not certifying someone that fails to meet the standards for the course and who isn't safe is a perfectly valid reason!. If you're unable to perform stage rotation, SPG remove and replace and other skills you aren't meeting the standards and aren't safe.
String: please learn to read its not me who is asking where to put my spg but the OP and on your way to school read also those books INTD,
IANTD don't mandate all left
Don't mandate all left
GUE and DIR are the same thing. You got that wrong too.
Dont mandate all left
Assuming you mean PADI they don't mandate all left either
While we're on the subject neither do TDI or BSAC
they all uses 2 al stage under 1 arm,
No they don't. You appear to have managed to be 100% wrong there. Congratulations. Quite a feat.
Enough explanation, I'm borring myself.
So how about explaining why you have to have them all left? Or why you have to check an SPG very very frequently and with no hands? And why its so hard to clip 3 things off to a D-ring?
