Sadly I wish I could use the warm clear water experience instead of the dark, 39 degree F, still learning on the CCR but my limit is around 140 ft while on OC it was around 150ft. I guess thats not deep air diving but thats what He is for
In general I feel I need to be more clear headed on ccr as there are more options in case of failure compared to simply turning valves on OC.
