OC Oxygen reg on Insp.

Pierre Farrugia · 16th April 2005, 18:27

Hello,

I am thinking of fitting an oxygen reg on the Oxygen side on my Insp. What you think about this? What reg. do you suggest,( pref. Scubapro )? Where do you attach this reg ?

Regards

Pierre

WHY do you want to do this?

I will have acess to my oxygen on OC, so for my sub 40m dives, I could have more options to breath from, I see it on other units as well!

I too considered doing this but Leon explained why I would not want to do this.

It is basically - if your going to want to breath your O2 then its as you are less than 6 m and in deco and if you are doing deco diving then you should be carrying external bail out any ways.

But as with anything on CCR it really is a peronal decision....

Could you not just attach a standard O2 clean reg and hose to your first stage?

Alternativly I think APD do some sexy quick discconects - I know Grant from the Hurricane uses these and has only one reg connected which he can move from Dil side to O2 side if needed - kind of a nice solution I thought..

I think like this even if you have min. deco , it still can be done. I will be using a flow stop to reduce possible free flows! Like this is you have some deco eg. less than 10 to 15min, can still be done for recreational dives. For deeper longer dives, stages are a must in my case!

Pierre,

I would recommend against this for very simple reasons. The supply bottle is very small. You would not get much duration. If the unit is running, you will get as much O2 as you need.

You could carry a seven liter or larger bottle with an O2 clean set-up to use from 20 fsw up (6 metres) as a back-up. If you then attach a quick-disconnect that fits the manual addition fitting, you can either breathe it OC or plug it into the counter-lung.

Cheers!

I second everybody's advise. Why complicate your life further by having another second stage on your Insp. Do your deco.using the Insp. as your Oxygen rebreather at the 6m mark. Carrying bailout and oxygen wasn't all that hard when we were all on OC, and now it's even easier on CCR.

Pierre, I suggest that if you want a bailout oxygen reg, use the quick disconnect system as found on the bcds. This way you only take one 2nd stage and rig it to the dil tank for the duration of the dive. In the case you ever need O2 as bail out in the shallows, you just disconnect the same 2nd stage from the dil tank hose and connect it to the oxygen hose feeding the O2 port of the breather.

I have practised this many times and it sounds more complicated than it really is. Taking just one 2nd stage instead of two prevents risks of diver taking 02 reg at depth instead of dil !!! in times of distress.
I never found the appropiate fitting for sale on the internet or any diveshop been to. Therefore I machined the fitting myself out of stainless steel.

Hmm. I wonder about using a quick connect fitting to plumb O2 if necessary into the KISS integrated OC DV.

I see where Pierre is coming from. If you are on a shallowish dive and have to bail, you have a) more gas and b) it's a better deco gas. I see it as a bonus for a situation where you've stayed longer at depth than anticipated and have had to bail. Yup, it's emergency stuff, but you can never have too much gas...

I have a Bob OC/DSC. The Dacor Viper reg on it swivels. I cut the hose from it very short and fitted a male AP GCS fitting (£23). I had three of the female fittings knocking about. One comes from the Dil and is fitted to the DSV. Another one was fitted to a yellow hose and then to the O2 manifold bar. So, if I want to I can disconnect the Dil hose and plumb the O2 one directly into the DSV.

I'm still playing around with the config. I'm not using the wing at the moment for buoyancy and my SSBOD looks like Bob Marley with all the hoses coming out. So I've plumbed the O2 hose into the autoair on it to see how it goes! (BANG!)

It worked fine on the last dive (and I had to use it too...). If it freeflows, I can disconnect the reg. If that doesn't work, I can turn the O2 valve off and on manually as required. It's for emergencies... (I carry redundant O2 BTW). I can also plumb any of the three female whips into that or the DSV, so if the DSV explodes I have something to breathe from, which in that situation would be nice...

HTH, Pierre. How's Ammers getting on out there?
