Scubapro Yoke to DIN Conversion Kits - 300 BarUse the Scubapro 300 bar DIN to convert your first stage from a yoke valve to a DIN valve. This is a necessary piece of equipment for divers who want to switch between regular pressure (3000psi) to high pressure (over 3300psi) tanks. Also, scuba divers who travel overseas and to the Caribbean will want to have a DIN to Yoke adapter in order to adapt to the tanks available at the local dive sites.
