I've been in diving for over three decades. I've seen people walk into an IDC and completely transform — not just as divers, but as people. And I've also seen candidates who struggled, not because they weren't capable, but because the timing wasn't right, or because they hadn't truly asked themselves the honest question: is this really what I want?

This article is my attempt to give you that honest answer. Not a sales pitch. A real conversation between someone who has trained instructors for many years and someone who is standing at a crossroads, wondering whether to take the plunge.

Why People Want to Become PADI Instructors

The motivations vary widely. Some candidates have been diving recreationally for years and want to turn a passion into a profession. Others are at a career inflection point — perhaps burned out in an office, seeking something more meaningful, more physical, more alive. Some are young adults who discovered scuba during a gap year and never quite came back. And a few are mid-career professionals looking for a dramatic second chapter.

What all of them share is a deep connection to the underwater world. That's the foundation. But passion alone isn't enough — and the best thing I can do for you, even before we meet, is help you work out whether the full picture aligns with your expectations.

What the Job Actually Looks Like

Let's be direct. Teaching diving is physically demanding, often seasonal, and rarely as glamorous as the Instagram highlights suggest. You'll be in the water multiple times a day, in conditions that aren't always perfect. You'll be responsible for the safety of complete beginners in an environment that punishes complacency. You'll deal with paperwork, equipment maintenance, and students who are terrified on their first confined water session.

And yet — for the right person — every single one of those things is deeply satisfying. Watching a student conquer their fear and descend confidently for the first time never gets old. The underwater world you'll guide people into is extraordinary. And the community of dive professionals worldwide is one of the most warm, international, open-minded communities you'll find anywhere.

"The day a student signals 'OK' on their first open water descent and looks up at you with pure joy — that's a feeling no job title can replicate."

— Dominik Weckherlin, PADI Course Director

The Honest Prerequisites

Formally, to join a PADI IDC you need to hold a current PADI Divemaster certification (or equivalent qualifying leadership rating from a recognised agency), be at least 18 years old, have logged a minimum of 60 dives at the start of the course (100 is recommended), hold a valid CPR and First Aid certification within the last 24 months, and have a physician-signed medical statement within the last 12 months.

But beyond the paperwork, here's what I look for in a strong IDC candidate:

The Two Questions That Matter Most

After years of conversations with IDC candidates before, during and after their courses, I've distilled the decision down to two questions. Answer them honestly and you'll have most of the clarity you need.

1. Do you genuinely enjoy being around people who are learning something difficult?

Teaching diving means being endlessly patient with people who are scared, confused, or physically uncoordinated in a new environment. It means celebrating tiny milestones, dealing with frustration, and finding creative ways to explain the same concept differently to different people. If that energises you — if you find genuine satisfaction in someone else's progress — you're thinking like an instructor.

2. Are you prepared to invest in your own development long after you certify?

The PADI Open Water Scuba Instructor certification is a starting point, not a destination. The best instructors I know are constantly reflecting, learning, updating their skills. They pursue specialties, ask more experienced professionals for feedback, and hold themselves to a standard higher than the minimum required. The IDC teaches you how to teach. What you do with that knowledge over a career is entirely up to you.

What a Good IDC Actually Gives You

A well-delivered IDC doesn't just prepare you to pass the PADI Instructor Examination. It reshapes the way you think about diving, about teaching, and about your own capabilities. You'll learn how the underwater environment actually works physiologically and physically. You'll understand learning theory and how to apply it to a nervous student. You'll develop the ability to assess risk dynamically and act decisively.

In my IDCs, I work with small groups — a maximum of 8 candidates — precisely because that depth of development requires real personal attention. By the end, I want every candidate to feel not just qualified, but genuinely ready: for their first class, for their first difficult situation in the water, and for the long arc of a career they'll be proud of.

So — Is It Right for You?

If you're reading this and nodding along — if the honest picture of the work excites rather than concerns you — then yes, an IDC is probably right for you. The underwater world needs instructors who are there for the right reasons: people who care deeply about safety, about their students' experience, and about the ocean itself.

If you're not sure yet, that's completely fine. Reach out. I'm happy to have an honest conversation about your background, your goals, and whether the timing is right. That conversation costs nothing and could save you from a decision made with incomplete information — or give you the confidence to commit fully.

Either way, the ocean isn't going anywhere. And when the moment is right, it'll be waiting.
