Over the last year I have now sold the last two diaphragm 1st stage regulators I had left, for the diving I now do, pistons will 'see me out'.
I have the parts [or know how to acquire them] and know how to service them.
All my regulators now are Scubapro or USD/Aqualung Conshelf [far too many of each] .
It's been piston for 90% of OC diving since 1968, just works for me [and keeps on working].
Never had a piston not supply gas when required.
This talk of "piston Vs diaphragm" never stops.:letsparty:
Edit: found an old Tabata and Sea Hornet as well, there is sure to be more pistons if I look hard enough.

A former poster here (who is now banned from SB) posted a video once that he took of himself on a dive. The diaphragm on his 1st stage blew out at 160’ and the video showed all the drama. At least he had a bail out pony bottle.


Go DD you overqualified for SB diver you! Is that a thing or a card "Overqualified Diver!"

Oops, my mistake, 180’ and the HP seat blew out which caused such rapid pressure increase that it blew out the diaphragm instantly.

If I remember correctly, after seeing that video that’s what made me decide to stick to my piston regs.
I don’t care if they are a maintenance pig and all the other stigma they seem to have, I like the simplicity, reliability and bullet proof-ness.
