Equipped and staffed dive centres in Cuba are located throughout the country. Bilingual dive instructors are certified by international agencies including the American Canadian Underwater Certification (ACUC), the Confederation Mondiale dÁctivites Subaquatiques (CMAS), Scuba Schools International (SSI) and more. PADI (US-based) does not operate in Cuba, but PADI certification is accepted in Cuba.
While dive centres do have Cuba dive equipment to rent, as in all developing countries there are occasions that the gear might be relatively old and worn (but still in working order). Locally Sourced recommend that if you are traveling to Cuba to dive frequently, you should bring your own equipment where possible (mask, fins, BCD and regulator).
If you are uncomfortable using any of the dive gear provided at any location, you should opt out of the dive and review other options.
