yoke

Selling my Sherwood Regulator set that I used when I first got into diving. Is a great yoke set up and has been serviced every year. Was last serviced this past June. Everything works perfectly with no leaks. Asking $250

Hey, anyone out there wanting to go DIN to Yoke ? I want your DIN ! and you can have my Yoke ;)

I'm sure someone will come up with the exact dive scenario this is required. Or at least knows someone who keeps one just in case! I was digging around looking for inexpensive regs and came across this gem. Any guess as to the purpose. I'll open with a solution for an SPG on a dual hose...
