So the DIR solution is?

<font color='#0000FF'>frogman,
i would think to use the dir/gue system your kit would have to fall into the accepted kit as used under gue,that said to give you a dir view on your own kit and your own diving,would require you to do it right for yourself with the kit you have.
gue is a training agency and is not or ever will be compulsory so any info the gue boys offer has to be gratefully accepted and whether adopted or not is still freely given by people who have paid for the experience.
if gue have a system/practise that suits you copy it,if not dont, but accept it is the gue way and end of.....
i am not a member of gue.
i am doing it right,for me!
cheers

<font color='#0000FF'>Barrie,

I'm in the process of modifying my kit config towards a minimalistic approach to diving based around what I can find on the DIR sites. Most of which makes sense to me and feels comfy.

I'll probably get my skills upto scratch and enroll for the DIR(F) and see what all the kafuffle is about, then make a command decision based on &quot;is it right for me&quot;!

Failing that, I'll adobt the skills/config that suits me and take it onboard.

Hi Guys,

I don't want to fuel the flames... I also rarely venture onto here, please don't be too nasty!

Stop Breathe think act!! (thanks Phil)

The correct DIR hose position is: (As Bob has said)

Left post-Backup, SPG, Suit Inflator (if not using Argon)
Right Post- Long hose, Wing inflator.

The reason is that the most common cause of cylinder valve failure mode, is roll off. The right post will not roll off, but roll on. The left post will roll off and close. In the DIR config, this would leave you without suit gas, backup reg, and SPG. None of these are, at that point, critical-you have gas to breathe and can maintain buoyancy control while you asses and deal with the problem.

Bear in mind that one of the DIR diving protocols is to asses your breathing every 5 minutes, and compare this to an expected pressure drop. If this was not to occur, then point one would be to check your isolator, point two to check the left post. It is also DIR technique to do flow checks (checking all valves) periodically, and certainly after any contact with an overhead.

If your left post is smashed or otherwise completely u/s, and you get hit for an air share, having the inflator off the right post gives you the option of breathing off the inflator (OK pretty difficult-but possible) whilst still passing off your long hose. Note this is not breathing off the &quot;bag&quot;-the idea is to press inflate and deflate buttons at the same time while breathing off the oral inflator.

That is the reasoning behind the wing inflator configuration! The entire DIR configuration is based on logic like this - many people seem to extract parts of it, without looking at the whole and point out &quot;shortcomings&quot;. It is really important-and I'm sure that all  DIR divers would agree, to be aware that gear is only a tiny part of what DIR is about. DIR is much more about diving skills and responses to situations. Whether you chose to follow a DIR philosophy or not, or chose to extract the parts of the system that you want to is up to you- but please be aware that the system is designed to be used complete!

Hope that helps

The original question was concerning what hoses go where? and I thought I'd answered that and given some reasons. &nbsp;Dave answered it and Adam has answered it too, with some more reasons. So why all the greif??

Somebody also asked &quot;so to DIR you don't use your suit to fly the dive?&quot; I assume you mean that the suit is not used for buoyancy. &nbsp;That's right, the primary buoyancy device is the wing. &nbsp;The dry suit is there to keep you dry! and is NOT &quot;backup buoyancy&quot;.

So, if anybody still isn't clear on which hoses go where, ask away and I'm sure we can clear it up.

Incidentally, another reason for having the wing off the RHP is because it is beneficial to have hoses crossing behind your neck. &nbsp;This reduces stress on the hose ends and you can hear and &quot;feel&quot; gas flowing in the hoses touching your neck. &nbsp;Also, it enables the use of standard hoses (a wing hose coming from the LHP would need to be really short). &nbsp;Also, if we are all configured the same, we can swap gear without major hassle.

How many reasons do you want?

[MATTBIN]

I assume that DIR doesnt like inverts?
Reasons are? I ask because to me inverted seems much more logical/practical. Access to valves is much easier therefore shutdowns are a doddle. I should add that I do not do overhead environments and have managed in the past to hook my single tank up in the shot line, so a pair of valves would seem to be really asking for trouble (in my case &nbsp; &nbsp;anyway, so far.)
But what are the factors that preclude inverts, I wont use the term wrong-way-up?
Given that inverts are used by some, does the LHP/RHP split still stay the same.

Hoses can get rather long, there are lengths which are nowhere near your head so you can't hear a leak, it calls for valve protectors which are claimed an entanglement hazard, and you look less of a dive god if you do it the easy way

[adam]

Hi again,

I've never dived inverted cylinders, so don't really feel qualified to comment-and I would guess that will be true of most DIR divers. Possibly the correct place for this query is on the Tek forum?

Suffice to say that I have no problem reaching my valves!

Adam
with respect I suspect you arent 49 or bounced down the road so many times via motorbike accidents that you had a season ticket in the A&amp;E casualty dept. I wish I could reach mine too, as easily as I can inverted. I dont see the point of struggling when a 'safer' alternative is available to me. If you can reach yours that way up then obviously its right for you (and others).

Best wishes
Matt

<font color='#000080'>Hi

You also lose the use of the butt Dring, which is used to store reels, stages, that type of thing. Because you will want to keep your isolator clear.
