Cave, Technical and CCR Training

We aim to provide the best possible training at Underworld, and draw on many years of diving experience in many different environments to help our students succeed. We are a TDI, BSAC and RAID centre and can also teach technical courses from IANTD and PADI/DSAT.

All our students will get a training package that is tailored to their individual needs. Cave, technical and CCR students get access to a bespoke DropBox that is packed with useful background information beyond the prescribed agency texts.

You can download a guide to the skills and equipment required for overhead courses here.

Our cave and technical training costs are inclusive of course materials, cylinders, nitrox, cenote entrance/boat fees, certification costs, equipment rental and lunch.

For cave courses, Underworld does not advocate or teach “zero to hero” courses. Students will normally require to gain 20-30 dives of cave experience between Introductory and Full Cave.

Cave training: $260 per day
Technical training: $260 per day plus student/instructor helium charged at actual cost
CCR Training $300, including cylinders, O2, air/nitrox diluent and sofnalime.

*The reason costs are "expected" is because at the higher levels, training is purchased and certification is earned. We will provide the best possible training during our packed training days, and give students every opportunity to succeed. It is, however, occasionally necessary to schedule extra days of training if requested by students.
