But aren't the other dives (cave, wreck, night, etc...) designed to give people an introduction to help them decide if they'd be interested in pursuing those kinds of things further? I thought the point of PPB was to improve overall diving skill. Again, I'm brand new so I'm just trying to understand this.
You are right about that in the terms of your response--I was just pointing out that the rules are technically the same for all of them.
