Could be...I know there is a site called Frogkick that features divers 'Doing It Wrong' - that is, the non-DIR way. But, there just might be a place such as you mentioned... See: www.frogkick.nl/ |

I never got into the hogarthian or the dir methods. It always seemed to me that the method one dives is up to the individual, as long as it is done in a safe and responsible manner. caveman
(MY GEAR DOES HAVE A SOMEWHAT RESEMBLENCE TO THE DIR GUYS, BUT I AM NOT A TRUEIST)

Yup. DIR has some great merits. However, like all things - once can take it too far. Too far to me is:
- expecting everyone to dive the way YOU think is the best
- criticizing those who don't
-and thinking that ANY other way but YOUR way is wrong, unsafe, etc.

I haven't commented here yet, but it is interesting what you've done with the Aquamaster. It really doesn't look like the original at all; it's very interesting too with the mouthpiece. I'm not yet convinced about it, and would be interested in hearing how your open water diving with it is.
I dive a lot in rivers with a lot of current, so I'm very conscious of streamlining. It seems that this mouthpiece would exert a bit more pull that the original, but I haven't really noticed it on my single-hose regs. I'm also interested in how the hoses are affected by the coverings--streamlining wise.
My impression of DIR folks is that, in their quest (zeal) for double or triple-redundent systems, they have not paid much attention to streamlining the diver. One other thought is that the old double hose regs, which have six moving parts (Mistral), or nine moving parts (DA Aquamaster) and the only "O" ring is the connection to the tank, may have more inherent robustness (less likely to fail) than two fancy new regs on tanks with two posts with multiple "O" rings. On another site (www.scubaboard.com), I asked this question and did not get good answers from the DIR folks. I had posted info about "O" ring failure rates from a product safety book I have (it's at work right now). Anyway, if someone asks about the relative safety of the vintage systems verses today's systems, have him/her count the number of "O" ring seals that they have, and then tell them that you only have one (the one between the tank and the reg);D
Anyway, very, very interesting. Give us an update when you get your rebuilt reg in the water.

SeaRat,
Thats quite interesting. I'd never thought of that! Thats one thing I did notice when I rebuilt my DA - no o-rings!
And divers comment tha vintage gear isn't SAFE to dive with? My Apek's had far more o-rings in it then my DA does!
Interesting...

I do not understand your comment on my mouthpeice. I made it because my old one was dryrotted and I am not a real big fan of the original mouthpeice because you have free flows when you swim with it out of your mouth. I thought that I could imrove upon it. I have the capability to change and custom mold my mouthpeice when ever I want (can't do that with the original). I have dived with these kind of mouthpeices on several different rebreathers and they work great. The pull is less than with the original mouthpeice and the hose covers are not even noticable when you dive with them
I too dive in rivers from time to time and I prefer the double hose because you can not even feel the mouthpeice in your mouth

Danny D,
You understood my question correctly. I was curious about drag, but you have answered it well. It is an interesting concept. I have never dived a rebreather, so this is pretty new to me. Stopping the freeflow is a novel approach which I had not even considered. It does sound interesting, so keep us informed as you get it wet. It looks really neat (an older guy's way of saying I like it).
John
