I just got back from DEMA. During the conference, I had to meet with a PADI rep to do an update. All the student and instructor manuals have changed somewhat. This includes new required skills where some were just previously recommended and the dive depth range requirements have changed. The exams are new. The instructor wetnotes slates are new and in a better sized format. I am still going thru the manuals. I will post a video in a few days of the major differences.
