As a trainee divemaster I had my first student today and I took her through open water 2.
I took her through her pre-dive safety checks and explained how a dive doesn't begin when you splash, but when you prepare your equipment, pack your gear and plan your dive(s).
She seemed a little nervous so we talked about the skills that we were going to do during the dive, what hand signals I would use and the steps of each skill.

This is where the instructors in the group get concerned. Maybe your description wasn’t clear, but it sounds like you taught the skills, which is a task reserved to the instructor, and it sounds like you didn’t explain the performance requirements, which you may not know because you don’t have the slates. Also, it isn’t clear who performed the in-water skill demonstrations, but it sounds like you did them, also a standards violation.
When you get your own professional liability policy, the fine print will tell you you’re not covered for accidents that occur while you’re not following agency standards.
Accidents do happen even in confined water training. I once had a student collapse on the pool deck before he even assembled his gear. If there is a claim, and you aren’t following standards, you’re on your own.
In this situation, if an accident had occurred, the instructor’s liability carrier would likely have denied coverage, and you would have been in the line of fire. In fact, you might have been in the line of fire even if you were assisting within the scope of your qualifications.
Also, if you’re old enough and settled enough financially to be taking the DM course as an expression of your diving hobby, it’s likely you have more assets than a full time instructor does. You might be the more attractive defendant.
The instructors who expressed concerns here are not being nitpicking jerks. We’re alerting you to the risks you’re exposing yourself to at a time when you might think you’re in training and safe from these concerns. You’re moving into the professional ranks now—fun must take a back seat to professional responsibility.
Best wishes,
