Intro to Tech.
Murcia · Costa Cálida
Year-round, 14 → 26 °C
Where recreational thinking ends and technical thinking begins — on twin tanks, long-hose, DIR.
This is the bridge — not a try-dive, not a sales pitch. A controlled introduction to the kit, the planning and the in-water discipline that separate technical from recreational diving. You leave knowing what tech actually asks of you, with the gear configured and the fundamentals drilled.
Honest about
the cohort.
- Recreational divers ready to commit to twinset and long-hose.
- Sidemount divers wanting a structured introduction to DIR configuration.
- Anyone aiming at Decompression Procedures who wants the right base under it first.
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.
Twin-tank trim & buoyancy
Static and dynamic trim on doubles. Neutral, level, motionless.
Long-hose deployment
Primary donate, secondary stow. Done slow, done right, done the same every time.
Streamlined configuration
Hose routing, clips, stages. Nothing dangling, nothing snagging, nothing forgotten.
S-drills & valve drills
Gas-share, valve isolation, shutdowns. Muscle memory under task loading.
Conservative gas planning
Rock-bottom, turn pressure, thirds. Numbers before the dive, never after.
Briefing & debrief discipline
Plan the dive. Brief the team. Debrief honestly. Repeat.
