What Does a Divemaster Do?

Divemasters are professional-level divers trained to supervise certified divers and assist instructors. It's a leadership role that focuses on safety, organization, and guiding — not teaching full courses.

Common duties include:

One of the best ways to describe it? You're the operational glue behind every good dive day.

Personal Insight:
"I'm going through Divemaster training now — and doing it locally in Chicago. For me, watermanship has been the hardest part. I'm not 25 anymore, and those stamina tests are no joke. But it's not just that — I also found the demonstration-quality skill circuit surprisingly tough. Making each skill look clean, slow, and controlled while explaining it underwater takes more focus than you'd think. Still, I wanted to do it right — not just pass, but actually earn the role. I'm not aiming to become an Instructor — this is where I stop — but I want to be the kind of Divemaster who makes dives better for everyone."


What Does a Dive Instructor Do?

Instructors are the ones who teach full scuba courses and issue certifications. They carry the responsibility for student safety, performance, and progression — from that first nervous breath to final checkout dives.

Key responsibilities:

If you love teaching and want to build a long-term career in diving, this is the track. But it’s a bigger commitment — in training, cost, and liability.

Final Thoughts

Divemaster and Instructor are both rewarding in different ways. Divemaster gives you the foundation and confidence to lead and assist. Instructor builds on that to turn you into a certified educator.

But not everyone needs to teach. Sometimes, leading dives, supporting new divers, and being the calm presence underwater is enough. That’s where I’m stopping — and it’s already made me a better diver.

Wherever you go, bring the mindset of a pro. That’s what really sets you apart.
