When I sink Gamma, there is an air bubble remaining in the ballast tank, the size is determined by the weight of the sub. If I have a first and second stage regulator feeding air to the ballast tank, the regulator will feed air into the ballast tank as I sink keeping the bubble the same size while I sink. Right now it is completely manual and takes practise but it works. I can use both systems ( manual or regulated) by simply turning the air supply on or off to the external regulators. With the regulator system, I would not have to worry about keeping the sub at an ideal weight. </div><div id="yui_3_16_0_1_1440673788233_2986" dir="ltr">Hank</div> <br><div class="qtdSeparateBR"><br><br></div><div class="yahoo_quoted" style="display: block;"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 12px;"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div dir="ltr"> <font size="2" face="Arial"> On Thursday, August 27, 2015 12:03 AM, Alan via Personal_Submersibles <personal_submersibles@psubs.org> wrote:<br> </font> </div> <br><br> <div class="y_msg_container"><div id="yiv1047596452"><div><div>Thanks Hank,</div><div>must be this one, the umbrella dive.</div><div><a rel="nofollow" shape="rect" target="_blank" href="https://m.youtube.com/watch?v=sflIEnkTth4">https://m.youtube.com/watch?v=sflIEnkTth4</a></div><div>Sent a reply to your post about using a second stage attached to your</div><div>ballast tank, but it didn't come back to me.</div><div>not sure how it would work!</div><div>Alan<br clear="none"><br clear="none">Sent from my iPad</div><div class="yiv1047596452yqt7882620191" id="yiv1047596452yqt69389"><div><br clear="none">On 27/08/2015, at 1:30 pm, hank pronk via Personal_Submersibles <<a rel="nofollow" shape="rect" ymailto="mailto:personal_submersibles@psubs.org" target="_blank" href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br clear="none"><br clear="none"></div><blockquote type="cite"><div><div style="color:#000;background-color:#fff;font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:12px;"><div dir="ltr" id="yiv1047596452yui_3_16_0_1_1440638982967_2475">made some dive video's today, posted one on youtube under Hank Pronk</div></div></div></blockquote></div><blockquote type="cite"><div><span>_______________________________________________</span><br clear="none"><span>Personal_Submersibles mailing list</span><br clear="none"><span><a rel="nofollow" shape="rect" ymailto="mailto:Personal_Submersibles@psubs.org" target="_blank" href="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a></span><br clear="none"><span><a rel="nofollow" shape="rect" target="_blank" href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a></span><br clear="none"></div></blockquote></div></div><br><div class="yqt7882620191" id="yqt10294">_______________________________________________<br clear="none">Personal_Submersibles mailing list<br clear="none"><a shape="rect" ymailto="mailto:Personal_Submersibles@psubs.org" href="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a><br clear="none"><a shape="rect" href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" target="_blank">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br clear="none"></div><br><br></div> </div> </div> </div></div></body></html>
