I looked everywhere online and found no results - just mostly stated "POSEIDON CYKLON 5000 REGULATOR". Do any of you know about "POSEIDON CYKLON SUPER 300 DEEP SEA DIVING REGULATOR"? What year this regulator 300 came out? I found one online for sale and thinking about buying it - but of course, I wanted to check with you guys first. :14:
