Underwater, you rely on yourself. SDI Solo Diver and Sidemount courses in Warsaw

I run every course myself. We do theory and pool sessions in town, and for open water we go where it's deep.

Training starts shallow

I measure progress by what you can do underwater. We repeat every procedure until it gets boring and you do it without thinking.

I run pool sessions at selected pools in Warsaw and at DeepSpot in Mszczonów, an indoor pool 45.5 meters deep.

  • Warsaw pools: up to 3 m
  • DeepSpot: up to 45.5 m

Courses

Every course is taught in English or Polish

SDI Solo Diver

Diving alone, with a plan and backup gear

You learn to plan and make dives on your own. We cover redundant gear, gas management and handling failures without a buddy. The course includes theory, pool sessions and open water.

SDI Sidemount Diver

Tanks at your sides, valves within reach

We build a sidemount configuration from scratch and practice trim and handling in it. I fit the rig to your body until everything sits where it should.

Package: Solo + Sidemount

You can take both courses in one cycle: less repeated theory, more time in the water and better terms. There's no price list here because I fit each course to the person taking it.

We do the first descents and set up gear in selected Warsaw pools. This is also where we repeat drills calmly in the evening, after work.

Wapienniki Sulejowskie

Flooded limestone quarry

Depth
up to 14 m

The quarry near Sulejów has bright walls and an uneven bottom. The water here is calm, so we use it for navigation and trim practice.

I'm a technical diver and I teach in Warsaw. Underwater I value calm and order, so I keep my courses that way too. We only go deeper once your hands know what to do on their own.
