What Makes a Great Instructor? Insights from My Years of Training Divers

I’ve met so many divers who are curious about technical diving but hesitant — thinking it’s only for elite divers or adrenaline junkies.

It isn’t.

Technical divers are thinkers.
They’re planners.
They’re people who care about doing things properly.

If you’ve got solid buoyancy, situational awareness, and a desire to understand your diving rather than just do it — you’re already halfway there.

Here’s how most divers start the progression:

  • AOW

  • Rescue

  • Nitrox

  • Deep

  • Then Tec 40

At Tec 40, everything changes — your awareness expands, your thinking deepens, and you start to appreciate the beauty of disciplined diving.

You don’t have to be fearless or intense.
You just need to be curious and committed.

IDC Prep: Common Weaknesses I See — And How to Fix Them

When candidates arrive for IDC training, I can usually predict the most common challenges I’ll see — not because the divers are lacking, but because these areas are rarely emphasized in recreational training.

Weaknesses I most often see:

  • Knowledge confidence — they underestimate what they already know

  • Teaching clarity — too much demonstration, not enough explanation

  • Nervousness while speaking

  • Limited situational awareness when task-loaded

  • Trying too hard to be “perfect” instead of being effective

What I tell them is simple:

You don’t have to be a flawless diver — you have to be a communicative one.

An instructor is not a performer — they’re a teacher.

IDC prep is about unlocking the potential you already carry — not transforming you into someone else.
