I said no, but that got me thinking, and I may not have realized that I was getting a air lock. Normally I dive Gamma heavy with no issues but at Lake Tahoe I was diving very close to neutral. The problem I was having at Lake Tahoe, was the sub leaning uncomfortable while submerging. I blame that on the weight of the sub and since the sub was light it could not push the water out of the vent lines casing a blockage. I like diving closer to neutral now so I installed 4 solenoid vent valves as an experiment. It has solved the problem completely. In fact I only need two valves to make it sink perfectly now. With all four valves open plus the two original valves open, the sub dives in 1 min and 30 seconds. Slow compared to Alec's sub but good for Gamma.<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica Neue";color:#26282A'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica Neue";color:#26282A'>My next challenge is to install a bigger port in E3000.
