<< There is also a third Apeks second which may be not have the balance chamber, and that must be the one Tod is talking about. I do not have any of those. >> George, I pulled the ZRD reference from a posting you made earlier this year: "REGS - BACK - I USE APEKS NON SWIVEL FIRSTS SET AT 120 PSI INTERMEDIATE PRESSURE WITH THE NON-AIR BALANCED BACKUP, AND THE AIR BALANCED PRIMARY ... I have fifteen of these regs,and ALWAYS have had them, ALWAYS have recommended them as seconds. The first stage is called the US4, and the second is the ZRD if not air balanced, 50 if air balanced. APEKS is when I do not want any problems at all." Regards, Tod -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
