I'm not going to tell you why I don't believe in using DIN plugs on my tank... It'll ruin your fun.
Actually, maybe I can, since your plugs don't appear to be afflicted with the problem.
Normally, if you use DIN plugs like these, if you put them in and then somehow the valve gets cracked open, it'll pressurize the space between the valve and the plug.
...Which isn't a problem until you go and try to remove the plug and you can't because it's pressurized and there's no way to vent.
I've seen on more than one occasion someone have to drill a hole in the cap to get it to vent, just so they could get the plug out.
Looks like yours already has a vent hole - with the string in it.
Now, why you'd need the plug, I have no idea... It's not like it protects anything (there's no o-ring on a DIN valve) - and you're still going to crack the valve open and blow the threads out before you attach those nice, new regs... I guarantee it.
But yes, they sure do look good.
I think you'll get annoyed with the plugs the first time you reach back to do a valve drill and the little plug-on-a-string gets in your way... Or the first time it gets caught between the tank and the cave ceiling or wreck wall and you ding up your tank, the plug, or both...
But yeah, they are definitely hot-looking.
Maybe you could just mount all of this stuff in a shadowbox, put it on your wall, and leave it... And continue to dive your Cressi stuff...
Kinda like Harleys - really cool to look at, but...
