That's almost unbelievable about that "instructor". I highly question the authenticity of his "PADI Instructor" certification. You have to have over 65 dives to even get your PADI Dive Master in the US, so there's no way this guy got a legit Instructor certification with only 15 dives. Someone scammed the system, or he manufactured his certification because there's no way he was a legit instructor based on the stories you've told.
The shit that you said that this guy did scares the fuck out of me. That's how people get hurt, or even worse, die. I wouldn't even dive with someone that careless, personally. It's sad & scary that people are certified without being trained. That's how accidents happen. It's basically the equivalent of a gaper ducking a gate and heading out in to the back/side country without proper equipment and training.
Fortunately, 98% of my diving is done with my old man. I've personally got 263 dives under my belt, & he's got well over 1,500, so we make a great dive team. We dive black water together all of the time doing search and recovery, so your life can literally be in your dive buddies hands at times. The local police & fire departments no longer have a dive team, so we are contracted through them to recover vehicles when they go in to the river, or the occasional jackass that jumps off of a bridge. (My old man is a chief of police & used to run the dive squad before they were cut due to budgets.) No way in hell I'd get in the mississippi river where I can't see more than 2 inches, and dive in high flowing currents with a guy that pulled shit like the guy you mentioned. fuck that.
