You went to see the ocean.
All you saw was the fins in front of you
Just as the dive gets good, your air runs out. You want to hang with an anemone for a moment, but your body keeps drifting past it. And your hand never leaves the inflator, because you are afraid of sinking.
You are Advanced with more than ten dives logged, so you wonder why it still feels like this. Some of you even hold an instructor rating and cannot say it out loud. Going back to the same instructor stings your pride. And quietly, you worry you are slowing your buddy down.
The person who hears this most often is the instructor who teaches instructors. So say it out loud — it is a normal place to be.
Diving is something the body learns. Stack up logged dives without knowing what to fix, and a bad position simply sets. It is the same as running every day without ever being taught how to run — the knees go first.
Once the body relaxes, the position follows on its own
Go down. Move around.
Come back up. That is all
No flashy skills. Just these three, done precisely.
Trim is a word borrowed from boats and aircraft: sitting level, tilting neither nose-up nor nose-down. For a diver it means lying flat and horizontal in the water. Get it right and drag drops — the same tank lasts longer and you finish the dive less tired.
The first hour goes back to your weights — how much, and where. Then how to manage the gas so you find neutral buoyancy before you ever touch the bottom.
No kneeling. No kicking up sand. Five finning techniques learned on top of a level body — and the same tank takes you further.
Most incidents happen on the way up. Holding the last 3 m, deploying a DSMB — the ascent stays under your control.
You cannot see your own trim
So every break, we watch the footage we just shot. Dropped fin tips, weight pulling to one side — it is all right there on the screen. Faster than being told a hundred times.
Every video and photo taken during the course is yours to keep. Watch it again at home and pick your own position apart.
There is one goal: that you leave knowing what to practise and how to judge your own diving. From then on you are comfortable without anyone standing over you.
We review the footage together, right there on the pool deck

People who came before you
Honestly, I was scared when I started diving in open water. But Dominique stayed right beside me, guided me steadily and built my confidence — what I felt was reassurance, not anxiety.
I had very few logged dives and it was my first time in a drysuit, so it was hard going. Dominique taught it carefully step by step and I adapted. Ulleungdo was a blast.
Dominique was absolutely excellent throughout the whole thing. My wife and I did Open Water and Advanced together, and we plan to go all the way to Master Diver.

The water holds three
- Intro class — first Monday of the month, 9 PM
30 to 60 minutes on Google Meet, no limit on numbers. See what gets fixed and how, then decide.
- A spot is only held once you pay
The pool session takes three people per session. Spots fill in order of payment. Sitting in on the class does not hold one. And paying early costs you nothing — cancel 7 or more days before and it is a 100% refund.
- Miss it and the next session is a month away
Sessions run the second Sunday of every month at 10 AM, at the Jamsil Olympic Stadium scuba pool. Once these three spots go, the wait is a month.
- Day one is not the end
One-to-one wraps up in a day. With two or three divers, you set the remaining dates with the instructor right after the first session. Video feedback and advice on your next step continue after the course ends.
When and where does it run?
the second Sunday of every month at 10 AM. The venue is the dedicated scuba pool inside Jamsil Olympic Stadium. One-to-one finishes that same day. With two or three divers, day one is together and the remaining dates are agreed with the instructor on the spot.
What if I pay, sit in on the class, and it is not for me?
Tell us 7 days out before the pool session and you get 100% of your money back. The intro class is open whether or not you have paid, so it is fine to hold a spot, sit in, and judge after. Even if you stop once the course has begun, the unused balance comes straight back.
Can I hold a spot just by attending the class?
No. The intro class has no limit, but the pool session takes three people per session. Spots are confirmed in order of payment, and once all three go, the next session is a month later.
Once the first pool session is over, is that it?
One-to-one finishes in a day. With two or three divers you set the remaining dates with the instructor right after day one. Video feedback and guidance on your next step carry on after that.
I am Advanced certified. Going back to basics now feels a bit awkward.
Most people who come are Advanced divers with more than ten logged dives. Certified instructors come too. Dominique is IDC Staff — he teaches instructor candidates — so he hears this more than anyone. If you want to see the step after this, look at Level Up.
₩300,000 for a day — is that not expensive?
This is not a group class. It is the cost of one instructor’s entire day. Nobody is watching the clock — you keep going until you feel confident — and every video and photo from the day is yours. A position once learned properly stays with you.
Can I come on my own?
Most people do. One-to-one is done in a day, so you only need to clear one weekend day.
I do not own any gear.
The pool rental set is enough. ₩20,000 per session, paid to the pool directly. If you do own gear, bring it — the rental cost disappears and it gets set up around your kit.
It has been a long time since my last dive. Is that a problem?
Past six months, ReActivate may come first. We look at your logbook and tell you. If you are not certified yet, start at Start Diving.
