Certification requirements, configurations and trimix depths are estimates for planning. Always check them locally and dive within your training. Compiled from web research (the Onorato, Denitto & Belmonte 1999 inventory in Thalassia Salentina, dive-centre and dive-site descriptions, Wikipedia, regional park laws, ISPRA/AMP documents, the SIMSI list of hyperbaric chambers; Sept 2026). Pins come from that inventory's coordinates (1″ precision, datum not stated): allow ±100–200 m. ~ = estimate. Rules change — check locally.
