No licence, no experience, about seven metres down. A straight account of an intro dive from start to finish.
An introductory dive needs no certificate and no previous experience. What it does need is about twenty minutes of attention during the briefing, because everything that makes the dive comfortable is decided there.

The briefing
You will be shown four things: how to clear water from your mask, how to equalise your ears, the hand signal for "something is wrong", and how to breathe — slowly, and never holding your breath. That last one is the only genuinely important rule in shallow diving. Everything else the instructor handles.
Going down
The descent is where most people struggle, and it is almost always the ears. You equalise by pinching your nose and swallowing or blowing gently, and you do it early and often, before it starts to hurt. If one ear will not clear, you go up half a metre and try again. Nobody is in a hurry.

At seven metres the colour is still there — red has not been filtered out yet — and the reef is close enough to touch, which you should not. Twelve to fifteen minutes goes quickly. Most people surface wanting to go straight back down, which is why so many holidays here end with a full course booked.
