Ok, I just had my first pool dives on a couple units last weekend and have I have been soaking the experience in...not quite obsessed yet, but getting there...it wasnt a class, but just an experience.

Please feel free to slap me if I'm wrong on these points/observations..but if you are going to slap me atleast help me.

1) Your loop is just like your BC...the more air in it the more it has an affect on your buoyancy..meaning injecting more gas into the loop is going to increase your lift in the water column.

2) If #1 is correct that would mean that if you are nuetrally buoyant and not changing depth...if oxygen is not being injected into your loop to keep your setpoint than you will become negative. Less loop volume means not as much lift...keeping in mind no adjustments to the BC and constant depth.

3) When ascending, besides venting the BC/drysuit...you can exhale out of your nose to lower the loop volume as the gas in it expands. Exhaling out of the mouthpiece is ok as well. If you have an OTS CL than as you exhale you pull the dump cord to let the gas escape.


Do I have the correct understanding?

Thank you.
