Inspo - reversing loop direction, what have I missed ?

curator

Ok, some clarification

Scrubber rotation is axial so the exhale tube sits on the left (looking at it with the cover off)

Brents detachable lungs - good idea - has possibilities but have to consider the effect of reversing all the hose retainers/D rings.

Cells rotated - excellent. This was really the type of stuff I was after. However... I'm using a Hammerhead, which for those who don't know, mounts the cells with their faces parallel to the scrubber top surface, so (I'll look closely) but I don't think its an issue.

For the curious - why do it?
Well, I suffer from a small lack of dexterity in my right hand, and whilst everything is calm, no problems, but if I had to do manual add of O2 via the cylinder valve when its all gone to S#1t, it could increase my task loading.
Put the O2 on my left side and a can do (and have done) it with my eyes shut upside down. Basically, my philosophy is tailor your kit to you.

Thanks for the thoughts so far. If there are any other points on the functionality of the unit, I'd welcome them.

Cheers

Fun Under Pressure

Use detachable CL´s. I don´t use the manifold for the O2 site. I buy long hose at © DTUAG 2005 (I am a dealer). No problems. I use a bailout second stage directly at the dil 1st stage and so i must use the manifold for the dil site. Without 2nd stage and ADV you can use long hoses w/o the manifold, than is the switch O2 right to left no problem i think.

Sounds like the change makes sense from the perspective of your limitations with your right hand, however your comment that 'my philosophy is to tailor your kit to you' should be kept within some context. IMHO, simple configuration changes to meet personal preference are perfectly ok, HOWEVER, massive subsystem alterations basically change the entire working principle of the specific unit. This is why it has been (unfortunately) impossible to cross-train on various systems without an entire course. For CCRs to really take off mainstream (enter the market in millions of sales), mfgs need to settle on a fundamental subsystem design principle that cannot be altered by the end user, with all else being 'features' of the unit.

I guess my point is...if shit hits the fan, has your unit changed so considerably that your dive partner cannot effectively render assistance (while stressed out/task-loaded). food for thought.

another option for you would be to buy a PRISM (O2 of left..I believe), adn dive with PRISM divers

Thanks for the thoughts, The conclusion i'm reaching so far from all the input here is that this change isn't a massive subsystem alteration. I haven't missed any major fundamentals and the unit will still function correctly.

This is very valid and always foremost in my mind, but I've been diving with just the O2 cylinder swapped over so far and by doing this change the manual add and cylinder will match (the brief will become less complicated).

If only....££££££££, CE, Training......

IMHO a diver should never look at his/her partners kit and assume its standard. In my diving circle we always carry out buddy checks were all function (both method of operation and checking its actually working) is done before each dive, therefore I can clearly brief my buddy on the changes. For example, the Jetsam BOV, Hammerhead handsets, Custom divers wing. So in conclusion, my buddy knows that he's diving with "My" rebreather that works in a certain way. No different from him diving with someone else for the first time with them on a Dolphin, KISS, Meg Etc. We have a mix of rebreather and don't tend to buddy based on unit type.

Once again, thanks to all of you for your input, and let me know if you think of anything else.

Cheers

How about adding a flexible cable to your O2 tank vlave. With the knob in fromt of you, the dextarity issue might be helpped and its only one part to add instead or a major rebuild.

Good K.I.S.S. approach.

Never used a "slob nob" (Uk name for them) and have thought about it in the passed but....
In engineering terms I'd say they're like a flexi drive. IMHO wouldn't the "play" in them, make controlled adding of O2 (in a solenoid fail situation) very hard?

Taking this approach a bit further - how about replacing the current short O2 hose from the manifold into the head with a longer one that includes a suitable shut off valve (Dave Sutton has posted several times on suitable ball valves IIRC). The ball valve would be positioned somewhere that you could reach with your left hand.

You could then use the ball valve to control addition of O2 in a solenoid failed open scenario, without necessitating major changes in the unit.

Of course, this only deals with solenoid failed open. Maybe one of John Routley's remote O2 add kits would put the O2 manual add button in range of your left hand too, to cover the solenoid failing closed too?

Just some musings at lunch time - might not be worth anything. Back to work now....

Cheers,

Isn't it the same problem when diving with OC buddies?!

When not on a tour, I dive mostly with OC buddies, and different buddies... And as they don't know sh*t about Rebreather's I have to tell/show them how to "save" me, if a problem occurs, that I can't handle myself, OR take the consequence and accept that only I can save myself.

Then one could say, diving with a buddy is just as "dangerous" as diving solo...
