Rebreather certified!

Just got back from Dutch Springs last week. I’m now certified on the Hollis Prism 2 rebreather! These things are great. I can’t get over the silence. It’s actually a bit un-nerving at first; you don’t hear the normal pneumatic sounds of an all-familiar regulator whining at every breath. But another look at your gauges reassure you that yes, it really is working!
