Well, I advanced to a new level in my current training today. I did my first two-bottle deco dive on the Sea Tiger. I was breathing Helitrox and carrying a 50% and 100% O2 bottle. My instructor was awesome and I led the entire dive from pre-brief (SADDDDD) to debrief. It wasn't a lot of deco for the profile that we chose, but it was still pretty cool taking 15 minutes to ascend from the bottom to the surface of the water and doing stage switches in between.l, I felt really comfortable the whole time and cannot wait until we do more dives.
