John, come dive in the cenotes . . . some of my friends spend their deco time using bubbles in creative ways
OK, then.
I start my cave training in January. Is this something that will be covered? I did not notice it in the NSS/CDS Workbook.

No, you learn this from your mentor
Also, you can use a feedback form on the Rochester Medical site and ask for samples in an assortment of sizes that you think might be in the right range. It's important to not get one that's too big because it will tend to come off as well as be uncomfortable where there's extra plastic stuck together, and you don't want to get one that's too small because it will restrict flow on your "hose" (not the one that came with the valve ).
