TECHNICAL DIVING SCUBA & CCR

The go-to source for cave diving, Trimix, and rebreathers.

THE NEOTEC STANDARD

Beyond certification

At Neotec, we don’t just sell maps; we build survival and exploration skills. Technical certification means you’re capable of handling multiple breakdowns in a hostile environment.

Sébastien Wilem, Instructor Trainer, applies methods drawn from his tactical experience and deep exploration (-230m).

Stress Management

Controlled “worst-case” scenarios to build your resilience.

Custom Configuration

Standardization of equipment (Hogarthian/Dir) for maximum efficiency.

Planning

Gas calculations, redundancy, and contingency planning. Nothing is left to chance.

01. ENCLOSED SPACES

Mines & Caves

A Neotec specialty. Learn to navigate the stone labyrinths of the slate mines in Martelange and throughout France. A cold, dark, and technically demanding environment that forges the best divers.

FAQ

TECHNICAL DIVING

Do I need to bring my own equipment?

For introductory levels (Intro to Tech), we can rent equipment. For Cave and Advanced Trimix levels, it is essential that you have your own perfectly fitted gear.

Yes, we have rental units (Liberty / Megalodon) available for the duration of the “Air Diluent” course. For advanced levels, we recommend purchasing your own equipment.

Hands-on training sessions take place at dams (Esch-sur-Sûre), Belgian quarries, or during expeditions in France (Lot/Dordogne) and Italy (Haven).
