Decompression Procedures.
Murcia · Costa Cálida
Year-round, 14 → 26 °C
Past the no-deco line. Planned staged decompression on twinset or sidemount — the gate course.
The gate. Every diver who calls themselves technical has been through this course. You will plan deco, execute deco, manage stops with redundancy and respond to gas problems that you previously had the surface to bail out to. After this course, your dives no longer end when the no-deco timer does.
Honest about
the cohort.
- Divers with Advanced Nitrox and a twinset (or sidemount) ready to go beyond no-deco.
- Wreck and cave students who need a strong deco foundation before going deeper or further.
- Recreational divers who want to dive the deep Murcia wrecks safely.
Drilled until
it's boring.
Skills are not a list to tick — they are habits to build. We drill them on land, drill them in the shallows, then take them into the dive.
Deco theory & tables
Bühlmann ZH-L16, gradient factors, conservatism — the maths under the computer.
Stop discipline
Hold the stop. Trim. Buoyancy. Gas. Time. In that order.
Decompression gas
EAN 50 as deco gas. Stowage, deployment, switch protocol.
Computer + table redundancy
Two computers or one computer and one table. Never one source of truth.
Lost-deco-gas contingency
Air-only ascent profiles, isobaric counter-diffusion notes, calling the dive.
Wreck/overhead conditioning
In-water task loading on the Cabo de Palos wrecks.
