Who dives which model of Russian rebreather?

Yankee Rebel

hi Sinus.. the cord is a buddy cord, i forget the actual literal name for it... keeps you from being seperated from the man youre responsible for, and he you.
the weapon in the picture is a Russian APS.. an underwater sort of assault rifle.. more info can be found in the following links:

Modern Firearms - APS underwater assault rifle

APS Underwater Assault Rifle - Wikipedia, the free encyclopedia

neat tools.. wouldnt mind the chance to try one out someday just for sh!ts and giggles... might be fun and all that good stuff.. till then.. will have to contend with shooting a .45acp underwater like everyone else.

SINUS

Thanks yankee,

I thought the rope was to prevent him from defecting to the west. You know, the old soviet system
Had seen the APS exhibited by Tula during a mil-expo.But I still love the dragunov
Vintage .45acp still delivered a good punch.

Cheers

Heck if my buddy was shooting one of those things I'd want to be quite sure he knew where I was.

Hi folks
Apart for the money that a IDA 71 cost, how much did you spend in the modification to mCCR?
Not electronick included, please.
Thanks
Mikel
PD: I've been thinking about it for almost one year to play with, but i don't know if is worth it¿??¿?¿?¿

I'm gathering the parts for my IDA 71 conversion and here is what I figure for conversion if you don't include the 71 itself or electronics:

Orifice/Bypass valve (really) roughly $100USD in hoses and McMaster-Carr parts
Oxygen Regulator Apeks DS4 $170USD new on eBay
Dil Regulator can be the same or one that you have already
Pressure blanking plug for ds4 $12 plus shipping from jetsam or a little more from tecme (15eur.)
2 x 15-19cuFt tanks for Dil and 02 say $150USD each with DIN vavle

Electronics -
P-port 30eur.
P-port cell holder narked at 90 or similar $160USD
PPO2.com kit complete with cell from tecme 330eur.
For this you can save some money if you build your own using LCD panel meters and can build a housing for it.

Now having said that I am in Canada so my prices are North american mostly - you I assume are in Spain so your sources may differ due to duties and shipping - maybe corallaro would have a better more local pricing idea.

I plan on saving by building my own components where possible plus I'm an OC instructor so I have access to cost based pricing at my local dive shop and 2 ds4 from my OC doubles setup.

Mikel-Deko

Thanks for the answer.
Just some questions:
You don't need any kiss style valve) pj, Hidrogom.
Can't you use the original tanks onboard and stages offboard?

Yes, the prices here for some spares are cheaper. We've bought some DS4 for 95€ > 114$

Best
Mikel

The DS4 price I just grabbed quickly off eBay - but good that you can get those cheap.

The McMaster Carr parts I described are a replacement for the KISS/ Hydrogom vavle it consists of a stainless steel or brass orifice, a filter, a shut off valve and a bypass valve for manual injection. You might have to do a little work to get them shipped to Espana and you may be able to find a local supplier of similar items but..

Some time ago you worked up a modded C-96 mCCR rig saying the ultimate intent was as a Bail Out rig to a back mounted primary Rebreather.

However you initially tested it & reported it out as a standalone intentional unit that you really liked in that config.

Did you ever go ahead and proof it out as a chest-mounted BO, with a back-mounted primary Rebreather ?? Did you ever use routinely as a BO,... and if not, why not ??

Hi Dan,

I dove it extensively as an intentional diving rig, using it to the exclusion of any other rig for 2 seasons. It worked just fine, and was well proven to about 150 feet. I dove the rig with (2) 3 litre bottles on a backplate and a KISS valve. The old C-96 has a smallish scrubber, and I did have one hypercapnia episode on the wreck of the Arundo in about 130 feet of water (2 steam locomotives there on the wreck!). I recovered the scrubber by just slowing down. Not sure why, never had any other issues with it. The C-96 Pro has a a better and larger scrubber and I would use that if I were doing it again. No downside to this system, I probably dove the U-853 in 110-130 feet fifty times with it. I was great inside the sub, small enough to easy-squeeze past stuff that other rigs clang and bang thru.

For a BOB, I never sorted out the issues regarding keeping it dry and ready to go. I've gone off on a different track now for a BOB, and believe that the best way is to keep the system sealed at 1 atmosphere in a rigid can until it's needed and then to open the can and activate the rig. I've got a rig under commericial development now for that, and without giving away too many secrets pre-patents, it weighs less than 4 pounds ready to go, and the scrubber runs on the breathing machine for 2 hours. Cylinder and scrubber are contained inside the CL. Photos show the rig on the machine breathing machine. Packed it's the size of a dive lite, and can be deployed in less than 10 seconds. The white stuff is just a paper towel so that the clamp on the test stand does not acratch the anodizing.

Who said that homebuilding has to be crude?
