Hello Pawel, Nice photos, and interesting harness. This photo with JYC is interesting, because he used a special regulator in close circuit, during one the conshelf experience. The deepest I think in front of Monaco, below 330ft. They used mix gaz , hélium, oxygen. So one of the little hose pull the mix and the second suck the mix to be purified ( removing CO2) O Screenshot_2024-04-11-18-24-48-611~2 by Patrick Michel, sur Flickrn Screenshot_2024-04-11-18-23-18-643 by Patrick Michel, sur Flickr Cheer's Fred

I just watched this film, and it was great. I noted that the Cousteau divers, when they were working on Conshelf 3, with their quad tanks that were used on Conshelf 2, were using single hose regulators. ‘Brought back some far-away memories. John

It appears that a second stage DH regulator with a remote first stage works best for the chest mount configuration.
My Russian AVM-3 would be perfect, since it's a second stage regulator. I've had some Spiro Narghiles that are also second stage regs. They'd be great candidates for chest mounting.
You can jump through some hoops and make 2 stage regs work as well.
A singlestage reg can't work very well attached to a remote first, since the operating pressure is far too low. But, they can be attached to an HP source and mounted on the chest as well, I'd think?

Hello Vance Yes, you are right, I am from Poland and apologize for possible language mistakes The "vintage diving" is not so popular idea in my country that's why I am here:) Some time ago I was interested about chest mounted DH regulator and I found plenty examples of using reg in this position... Even belly mounted by modern, professional diver if you like Finally, I found an article about Poumondeau by Georges Herail. He made innovative scuba regulator also in chest mounted version. And small front mounted apparatus. Compact set for "shallow water fish watching" is very interesting...you can easy take it with suit and basic gear in to one bag. Or give it to your child to show "underwater world" beauty ... So I have to make one like that:) I used my KAIMAN R7 single stage unloaded with venturi nozzle regulation - it's easy to maintain on the chest position. Tanks 2x2L per 200 bar are not so big/heavy so could be easily care on belly. Second regulator (UAN-82) and pressure gauge was added for safety. Regulator was tuned and tested few times up to 3m and was OK. I found a contact with retired Navy diver experienced with Kaiman. He was the one of first divers tested and putting the Kaiman in to Navy service in the 1970s also serviced them for years. He was surprised but happy that someone is so "crazy" to do something like that with old gear. He has a lot of original spare parts and he agreed to check & prepare my regulator for "safe" deeper diving. It will be nice I hope that now all will be well visible...thank you again Vince Nice photos, after finishing, all the that I begin, I think that I am gone try chest mount. I like your little twin, could you post other photos, to well see the manifold, and how you hook the reg. I like the pressure gage and his position for the reading. Cheer's Fred

Hello Chest mount in action. The harness seems to be pretty cool 😎. Fred

Hello Fred Yes, it looks like parachute harness a little but you can make something 'universal" which will fit to every diving harness, BCD etc. I see combinations : 1. Tank(s) backside + HP hose connection + 1 or 2 stages reg on the chest. 2. Tank(s) backside with 1st stage + MP hose connection + 2nd stage reg on the chest. 3. Small tank(s) set on the chest with directly connected DH 1 or 2 stages reg also SH is possible. 4. Something else ... I choose the 3rd as compact size & weight, technically the simplest and front mounted as safer "equivalent" of small oxy CCR (20-30 min shallow water diving) which I build but unfortunately shouldn't use I'm afraid that my set photos and other info will bring nothing new to the topic ... so do you want them here, on this topic or you prefer as private message to not waist forum space? Regards Pawel

Scuba outside of the US is always interesting. No worries about forum space, since photos have to be stored elsewhere. There is a lot of information already available here on the forum, but after a few years, there's a (partly) new audience. Also, you have to dig pretty deep sometimes to find a topic/thread/subject.
I think it's worthwhile to re-introduce a subject as it applies due to an idea, acquisition, or curiosity. I often get a piece of equipment that has been discussed before (or something that might not have) and think others might like to see. Many on board might not have ever heard of some of this stuff, noobs and OGs alike!
