My thinking is that I set the downstream pressure to be just above ambient pressure. So when descending the regulator should be supplying air just above water pressure. Don't see any chance for water entering the vent hole in this state. When ascending, air should be venting from the hole so don't see how water gets in during this state as well. So I don't see a state in which water is going into the vent hole. </div><div id="AppleMailSignature"><br></div><div id="AppleMailSignature">As I have had only one dive with this regulator can't really say to much on operating experience. </div><div id="AppleMailSignature"><br></div><div id="AppleMailSignature">When I get back from Australia, I plan to take the boat out for a 150 ft dive so I should get more experience with the regulator then.</div><div id="AppleMailSignature"><br></div><div id="AppleMailSignature">Regards Cliff<br><br><br><div>Cliff Redus</div></div><div><br>On Sep 30, 2015, at 8:30 AM, Alec Smyth via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br><br></div><blockquote type="cite"><div><div dir="ltr">Thank you!
