<div>Brian,</div><div>Yes Gamma has the O2 supply inside the sub, it used to be both inside and outside when I got it. I know it against the rules but I prefer the O2 onboard for safety reasons. I think there is less risk of a tank rupture than a O2 line failure. If your stuck down there, I think the O2 and absorbent should be inside the sub. Elementary is set up for external, and for weight reasons probably will stay that way.</div><div>Hank</div><div><br></div>

<div><div><div><div><p>All, I am purchasing the system components for my K-250’s O2 system. 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).
