What is the issue old wise one?SparticleBrane:Paula, I could be reading this wrong, but I'm not necessarily sure that breaking standards was Benthic's concern...
As Paula said, she was cavern and had an instructor take her on a dive one level up.
Here goes a quote from my cave instructors website on guided dives.
Because your guide is a fully-qualified Cave Instructor, it may also be possible for you to make guided dives that are one level up from your current level of certification. This is because the circumstances of your guided dive are essentially the same as if you had enrolled and were taking part in the next level of training.
So again, where is the issue (other than the gas management one)?
