Hello Beside the doubelhose mouthpiece reg. I have build differend type's of the oldest Cousteau Gagnan let's say CG43 by using older Dräger firefighter or gasmask reg. parts . If the flappervalve on the green spider is removed , and the five opening's on the backside are closed with the round gray pcv plate (shown bottom right) , this second stage is usuabel for a doubelhose mouthpiece reg. In the way it is now (without the gray plate), it is for an CG43 or other usual doubel hose reg's . Another easy and cheap version is this : The separation of the first from the second stage gave the freedom to place the secondstage on the backplate . Greetings Rainer

It looks like we are getting a view of the original Gagnan regulator adaptation. Is that correct? We've always been fascinated by the original scuba, with those really long tanks and the square regulator.
Now, the question is, how does it breath? Is it giving enough air by today's standards?

Es sieht so aus, als würden wir einen Blick auf die ursprüngliche Adaption des Gagnan-Reglers werfen. Ist das korrekt? Wir waren schon immer von der ursprünglichen Tauchausrüstung fasziniert, mit den wirklich langen Flaschen und dem quadratischen Atemregler.
Die Frage ist nun: Wie atmet es? Gibt es nach heutigen Maßstäben genug Luft?

Hello John
Yes , the reg. comes close to the orginal Gagnan reg. Two separated upstream stages . As Gagnan I used devices designed for a littel bit dfferend use . No wonder , the result is nearly the same even 78 years later . I build an 3 x 4 liter in line tank gear for the CG43 reg. It was very uncomvortabel on the back , especialy on the spine . Maybe lifting up the middel tank will work .
The breathing is perfect , easy and very precise .
Both stages are from the wellknown company "Dräger" from my hometown Lübeck . Take this in place and that i like the typical breathing of two upstream stages more than ventury .
Is it giving enough air by today's standarts ?
I can't answer this question by proof , because I have not the nessesary test equipment . The Dräger PA38 and Secor 200 diving reg. used most of the same parts and where recomended up to 50m (164 feet) in former times . I know from experience , you can dive with in deept's you may have problems with yourself . The small corrugated gas mask hoses on the pictures will work up for 100 feet easy diving . Up to now I have not made an real test . With standart 1 inch hoses i see no limitation up to max deep's recomended by today's divingorganisations .
