  • Advanced Open Water + 50 logged: Komodo, Nusa Penida currents
  • Advanced + 100 logged + Nitrox preferred: Raja Ampat, Banda Sea, Wakatobi liveaboards

What to bring vs rent

  • Bring: dive computer, mask, prescription if needed, log book, certification cards, dive insurance card (DAN strongly recommended)
  • Rent on-site (cheap): BCD, regs, fins, tank, weights
  • Bring if particular: own regulator if you're picky, own wetsuit if non-standard size

Liveaboard vs land-based

| Land-based | Liveaboard | |---|---| | Cheaper (USD 80–150/dive) | More expensive (USD 250–800/day all-in) | | Mix dives + sightseeing | Pure diving focus | | Better for couples with non-diver | Better for serious divers | | Limited site range (day-trip distance) | Reach remote/distant sites | | Land showers + better food | Boat life with limits | | Bali, Bunaken, Lembeh, Gili | Komodo, Raja Ampat, Banda |

Insurance

DAN (Divers Alert Network) membership and dive accident insurance are essential. Standard travel insurance usually does not cover diving below 18m or any depth without certification.

Common mistakes

  • Booking advanced dive trips before logging enough open-water dives
  • Skipping dive insurance
  • Not allowing 18–24h between last dive and flight (decompression)
  • Booking Komodo in wet-season storms (Dec–Feb)
  • Underestimating Raja Ampat costs (liveaboards are premium)
  • Combining diving with serious alcohol — dangerous and operator-prohibited

Verify before acting

Confirm operator certifications (PADI 5-Star, SSI, ANDI), dive insurance acceptance, and your individual certification level meets site requirements. See disclaimer.
