Technical diving exceeds normal recreational scuba limits, exposing divers to greater risks that require specialised training and equipment. ITDA offers entry, intermediate, and advanced technical levels: Nitrox, Extended Range/Staged Decompression, CCR Rebreather (to 100m), Cave Diving, Mixed Gas/Trimix, Gas Blender, and Technical Rescue. ITDA has developed technical diving in 65+ countries since 1998, with upgrades available from Advanced Scuba levels.
