Any new rebreather diver will be a little over tasked at first when he/she have less than a couple dozen rebreather dives. But after you gain the underwater experience needed, conducting video and still photography becomes easier on a CCR than OC.
Why? More bottom time, less silting, no bubbles in the photo, less decompression times, cheaper mixed gas dives (HE).
Do I use my rebreather for every dive?
No and here is why.
If the dive is short 30 (minutes) and shallow (60ft or less) and what I am shooting doesnt require bubble free (open ocean - no cave or wreck) than I use side mounted 80's.
Why sidemounted 80's? So I am self redundant and not relying on a dive buddy.
