I am new to the forum but not to diving, so nice to meet you all! Anyways, I have dove doubles for as long as I remember and reciently on a trip to Catalina Island, California, I used the same setup on a single tank. The dive was going great, but half way through the dive (ascent to about 20 feet), I tried to dump my air and it would not do it. I even went upside down trying to pull the dump valve on the bottom of the wings and no air came out. I finally turned over and emptied it with an inflator pull. What is going on here? Gusset cord? If it is, how tight do you make it? Thanks for your imput.
