The way you called the thread wasn't great. You did not have a student. You're the student and were allowed by the instructor to show a couple of skills to another student. That's probably what really happened, right? Of course as a beginner with under 50 dives and as a DMT you can't have any studends or conduct any training.Yep, and some people even pushing that we're both lucky to have survived!
If that instructor actually let's DMTs conduct full training dives, the instructor is a complete idiot. I kinda doubt that's what happened though.
