I am not a SCUBA diver so I lack some experience with regulators. I am considering sealed/balanced options for the first stage regulator (it will create an intermediate pressure downstream of the O2 tank (located external of the hull). These get pricey and I don’t really want to overspend for options I do not need (sealed vs. not, balanced vs. unbalanced, O2 ready vs. needing cleaned).</p><p class="yiv4008541596MsoNormal"> </p><p class="yiv4008541596MsoNormal">A couple of questions:</p><ol style="margin-top:0in;" start="1" type="1"><li class="yiv4008541596MsoListParagraph" style="margin-left:0in;">They sell regulators that are already suitable for 100% O2 use.
