Thanks for posting that. I feel like I have owned and dove a DX after reading your story.

Nice article Stephane!

I agree with you though. I think maybe for the time people said it gave a lot of air, but compared to the Mistral or any modern regulator it doesn't. I think people often repeat what they've read and say that the DX gives too much air. It's a slightly less powerful Mistral.

I think if you were used to breathing a DA Aqualung with no venturi it was probably a lot of air. I still have a DX, like yours, in original configuration and I dive it.

I really like it, but it's not the best performing single state regulator. The DW Mistral is.

I may have to disagree with you on that Ron. A Healthways Gold Label set up properly breaths really well.

That may be Herman. I've never used one. For whatever reason, HW gear comes across as kind of junky to me. Maybe it was their marketing and branding. I'd try one if someone brought it to a dive though.

Although I swear by the ultra easy breathing of my 1958 Mistral I gotta agree with Herman that there is a "sweet spot" on my HW Gold Lable (and Gold Label only) that if you get it adjusted just right you just think about getting air and it steps up and anticipates your desire. If not so adjusted it breathes like a Mistral, still very easy. My 2 psi.

I own a Gold label and a few Mistrals. If a Gold label has a USD hose and mouth piece set and is in good tune the Gold label will edge out the Mistral, but they are close. From a build stand point, the Mistral is just plain better. Heavier duty all around. I like them both. Given the choice though, I take my DivAir everytime. One day perhaps I'll be able to dive the Overpressure and find out for myself how they breath.

Thanks SurfLung, it means a lot to me, English is not my mother tongue and it is challenging to communicate feelings and sensations!

Thanks Ron, I do agree with you, it needs to be placed in its context, compared to an Aqualung Trademark DX provides more air.
