Dave,
I know that dives like these are nearly experimental but staying 30min with a flow of 13.5bar, you should be using the upper part of scrubber, wright ? Could be a dive like this make you use scrubber more efficiently due to using different fronts or I understood everything wrongly? Do people use their scrubber for 2 deep dives, eg in the 60m range?
