While on a dive vacation in Hawaii I won a new AL Zuma which included the Air Source 3. I took it along on a recent Caribbean trip and tried it out. The problem I encountered is that the AS 3 corrugated hose seems to be about 2 inches too long to comfortably hold in my mouth when turning my head to the left. Some users claim that bc air can be purged by pulling on the hose, but I found this to be difficult at best unless I turn my head to the far right. I wonder if AL sells a shorter hose from the bc to the Air 3 connector. That might partially solve the problem. With the current configuation it’s not a comfortable set up. Any thoughts? BTW, I do not not intend to abandon my octo reg.
