Nichole:bookboarder:Ok... I see... I think.(Not being snarky, but still kind of curious as to why the descrepencies... But, I supposed that I shall remain in the dark on that... ) My buddy and I are able to do it, although, obviously, we'd use our octo first, if we had to, we could do buddy breathing.
To clarify:
-NAUI requires teaching air sharing via octopus, and octo sharing is required in OW as a certification requirement.
-Buddy breathing is not required but may be taught as an option. It may not be substituted for the octo ascent for certification.
-If you did ONLY the buddy breathing, your instructor did not follow standards. Is it a big deal? Not my call, but if you can buddy breathe during an ascent I'd bet you'd have no trouble with an ascent on octo.
