moose_hk:As I told you RBs are a tool as a marine biologist I sometimes need to use them.
As for BS and blinkers - no mate that is an opinion, informed by several hundred hours of RB use so no need to look sideways. You are welcome to yours as am I so wind in your neck eh!

If I am welcome to my opinion, why do I have to wind my neck in :06:
Now you said that most CCR's other than the Mk15 have a problem with moisture on the sensor face due to placement in the loop. Now if that is not BS can you please point me to the information and tests done to show this, as my experience with a number of CCR's tells me otherwise!
As for your "several hundred hours of RB use", maybe you should take a leaf out of Mr Richard Pyles A Learner's Guide To Closed-Circuit Rebreather Operations
Now that I have spend more than 200 hours diving with a closed-circuit system, it is clear that I am still a rebreather weenie.
