Thats a really really good point.....and one I had not properly considered.

This is part of the reason I decided that open loop wasn't really the "total answer" it's been purported to be. All of my rebreather instructors advocate closing the isolator valve upon reaching the the bottom. If fine motor skill is going to stop you from switching to OC on a BOV, it's also going to stop you from opening the isolator valve on an ADV and going open loop (Provided your unit has an isolator valve).

Open loop is a great tool and one that deserves to be in the toolbox. but just as the screwdriver doesn't do the job of a hammer/wrench/saw/etc., open loop is not the answer to every gas-need problem.
