Recap of Evolution CCR Training with Richie Kohler

I just posted an article in the Article section of SB about my Evolution training with Richie Kohler. The article can be found here Evolution Rebreather Training with Richie Kohler

I wanted to post this discussion thread here in Advanced Scuba Discussions, as this course was a no decompression course, with the deepest depths of 110 FSW.

If anyone has any questions or comments, feel free to post in this thread, and I will also ask Richie to reply to any questions for him about Evolution training.

Nice write-up Howard.

Can you explain why it was (or seemed to be) easier to breathe the unit >2 atm?? That seems counter intuitive since the deeper you go, the more dense the gas passing through the scrubber becomes.

It felt easier to breathe once there was pressure against the counterlungs. Or at least it seemed that way.

Actually Richie says it's 20 Feet, and not quite 2ATM's as the point where it should breathe easily. Yes it is the pressure.
