Hi all,
Just to let you know that a new article is available on my website
Cedric Verdier, Cave, Rebreather, Technical & Recreational Diving. Articles
"Comfort and efficiency with a rebreather" is just about that: trim, buoyancy control, propulsion, etc.
It's a pdf document with a few pictures so don't hesitate to download it and improve it with your suggestions.
Cheers
