the problem isnt the regs its the cylinder valves.
i would imagine it would cost quite a lot for shops to swop valves for the more recent valves that can be used on either din or yoke.
yokes are rated to 232 bar.
din are rated to 300 bar
it's a bit obvious which are the best.
anyway not wanting to use an adapter i have swopped out my din for a yoke for the holidays.
a couple of the tech shops have din but for some reason these are not available for back gas .
anyway 2 weeks to go and depite the din/yoke thing i'm still looking forward to a bit of jeep diving.
I'm with you Mala - I want DIN where I dive. I also want h.p. steel cyls. of larger vol. ( 120's are fine ). I just got back from Coz. & had no trouble finding what I needed ( Jim Baldwin is right-on-the money with his info. ). My biggest concern with the yoke connection is o-ring extrusion/failure ( admittedly, this problem is statistically rare ), this possibility is eliminated with the "captured" o-ring feature of a DIN connection.
If more folks make noise about this, I'm sure the ops. will respond, hopefully sooner than later.
