Intro to Cave.
Murcia · Costa Cálida
Year-round, 14 → 26 °C
Past the daylight zone, on a permanent line, in a strict team. The real overhead environment with hard limits.
This is the course that separates cavern divers from cave divers. You leave the natural light zone behind, follow a permanent guideline, dive on the mainline with strict no-jump rules, and learn what it actually means to be deep inside an overhead with no direct surface. Heavy on planning, gas discipline and team protocol. Strict on prerequisites. There is no shortcut here.
Honest about
the cohort.
- Certified PSAI Cavern divers wanting to step into the full overhead environment with controlled limitations.
- Divers planning the Full Cave course who want to spread the training across two trips.
- Cave-trained divers from other agencies wanting a Cueva del Agua-specific orientation.
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.
Linear penetration
Mainline only. No jumps. No circuits. Discipline before depth.
Lost-line drills
What you do when the line is gone. Slowly. Methodically. Without panic.
Lost-buddy drills
Search, call, ascend protocol. Decided before the dive, executed in it.
Strict gas thirds
Out, back, reserve. The reserve is not for fun — it is for the wrong day.
Markers & arrows
Personal markers, directional arrows, non-directional. Read them. Use them right.
Cave navigation
Reading the cave. Mental map vs. the line. Following the team.
Failure protocols
Gas loss, light failure, freeflow, cut line. Drilled until they are boring.
Trim & finning in silt
Helicopter, modified frog, reverse. The cave never gets to see your fins kick down.
The shape
