Peter,
My question is on just how big of an exhale you do when diving this way.
While playing around with this all winter, in shallow water, I felt the blood shift after a single dive, or two at the most, and really liked how easy the decent was- plus, I was able to dump a full 10 pounds off of my winter weight belt.
I found my self taking a big breath, exhaling completely, and then diving. Re-reading through many of these posts it sounds like other divers are taking some type of partial inhale before they dive- which would extend both my depth and bottom time.
So, how big an inhale/exhale do you take before decent?
Thanks,
Jon
