Below
the line.
A technical-only dive operation on Spain's Costa Cálida. TDI & PSAI training from Intro to Tech through Full Cave and Trimix — and guided expeditions on the wrecks of Cabo de Palos and the only warm-water cenote in Europe.
One instructor.
Two divers.
No theatre.
Scuba Murcia Tech runs as a single-instructor operation. One team in the water at a time. Briefings that take as long as they need. Debriefs that don't get skipped.
Programmes are TDI and PSAI — the floor. What you leave with is cleaner hands, conservative gas, and dives that look like the briefing. We do not teach recreational. We do not teach try-dives. The cohort is people who want to go deeper, longer, and into the overhead.
Cueva
del Agua.
A freshwater–saltwater halocline cave in the Sierra de Almagrera, twenty minutes from the marina. Clear. Geological. The only warm-water cenote in Europe — cavern tours for open-water divers, full penetration for cave-trained teams.
Two and a half hours,
past the halocline.
November 2023. A penetration of 850 metres into Cueva del Agua — 30 °C past 12 metres, fresh above the saltwater. Shot by the team, not borrowed from stock.
The full ladder.
Tech and cave.
Nine programmes, from your first twinset to autonomous full-cave. Every step taught one instructor to two divers — and on dive sites you'll see again at the next level.
The bridge from recreational into technical thinking. Twin tanks & long-hose, DIR fundamentals, dive planning and in-water skills in a controlled environment.
3 days · Twinset
EAN 21 through EAN 100, within your current cert level, to a maximum of 40 metres on dives that do not require staged decompression. Twinset or sidemount only.
2–3 days · 40 m
First step beyond no-decompression diving. Planned staged decompression with twinset or sidemount, to a maximum of 45 metres. The gate course of tech.
3–4 days · 45 m
Advanced Nitrox & Decompression Procedures taught together. Max 45 m, gases up to 100% oxygen, unlimited decompression time (gas-permitting). Our recommended path.
5–6 days · 45 m
Beyond 45 metres and up to 55 metres using staged decompression for depth and extended bottom times. Up to two stages with twinset or sidemount. The depth gate to trimix.
4 days · 55 m
Planned decompression on a recreational single-tank system with one stage. Maximum 40 metres, limited to 40% oxygen and 15 minutes of decompression time.
3 days · 40 m
A two-to-three day course giving you the skills to safely explore the cavern environment within the natural-light zone. Strong emphasis on planning and safety — the prerequisite for Intro to Cave.
2–3 days · Light zone
A three day course developing the skills required to safely enter and explore the cave environment with strict limitations. Strict pre-requisites and heavy emphasis on planning and team protocol.
3 days · Cavern req.
The ultimate of diving courses. A seven day programme to certify the cave team as autonomous — complex navigation, jumps, traverses, circuits and full mainline protocols.
7 days · Intro to Cave req.
Every frame.
Every 7.5 seconds.
Every photograph on this site, on rotation. Wreck to cave, kit to team — in two minutes you have seen the whole field.
Tech diving isn't about going deeper. It's about going on the same dive — every time.
The water,
as it is.
Caves, wrecks and open-water training in Murcia and beyond. No stock photography — every frame is ours.
The clearest, calmest tech instruction I've had in twenty years of diving.

We came for the wrecks and stayed for the cenote. Unlike anything else in Europe.
OSLO · INTRO TO CAVE · 2025
Personal. Precise. Unhurried. They debrief every dive — and it shows.
