Then, I came across an article in SmartGroups which talked and taught me much about using one mix of gas in a different jet in my Dolphin (say 40% in 60% jet). And BOOM! I now have almost 120 minutes of gas at any depth.
That's how I use mine, I've been looking at SCR trimix and it seems workable, now I just need to put theory into practice!
