If you have a regulator set with a DIN connection and have a dive trip coming up, make sure you pack a DIN-to-Yoke converter. This adapter allows you to use both DIN and yoke valves, as you can simply transform almost any Yoke/international valve (also known as a K-Valve) into a DIN valve.
Comes with a sturdy grib knob to tighten easily and with a polished finished.
