CHAOS JJ-CCR prebreathe

[@wowfreaker]

Nice, simple but good video. What is normal for a technical diver could be beneficial for a rec diver. Knowing what you're about to do and visualizing and testing it beforehand takes away guesses and gets you prepared for business. And with business I mean nice wrecks.

sun flare is a nice touch... artistic :)

Pure luck ... especially in UK :)

Thank for the video. However, you should also close your nose when you do a prebreathe. False negative could be a real issue here

Thanks for your comment and I agree partially… Somehow if you don’t know how to control your airway then you can close your nose (or wear a mask). I would suggest developing airway control and awareness of what the rebreather is doing and why it’s not working (eg nose breathing)
