At my home uni, that's the majority of the tanks. Usually I forget about that, but I'll check at this next place. Thanks!See if your new summer dive job has DIN valves you can use for the duration. There is a pretty good chance you have at least occasionally used your DIN plus yoke adapter 1st stage on a DIN valve with a yoke insert rather taking advantage of the DIN. An insert on a convertible valve can be removed with the proper hex wrench.
