Editor's pickSuunto Ocean
The first dive computer we actually wear between dives. Maps, GPS on the surface, and an AMOLED screen you can read at 30 m in Similan sun.
Warm water, long days, carry-on luggage. Every item here has been on a boat out of Chalong. Links go to Suunto and Scuba.com; we earn a commission, you pay the same.
Your most important piece of gear. Suunto and Garmin, from first computer to sonar-messaging flagship.

Best value
For liveaboardsFourteen dives in four days is a lot of gas plans. The EON Core's big screen and rechargeable battery are built for exactly that week.
First computerIf you just got certified at Racha Yai, this is the computer your instructor probably wore. Nothing to break, nothing to charge.
LuxuryDiver-to-diver messaging via sonar, a 200 m rating, and a watch you wear to dinner. The big-ticket toy.
What you breathe from at 40 m on Hin Daeng. Buy once, service yearly.
Cold-water toughOverkill for 29 °C water — and that's the point. It breathes like nothing else at 40 m on Hin Daeng.
Guide favouriteAsk ten Phuket dive guides what they breathe from. Seven say this.
Travel-weight jackets and harnesses that dry on a longtail.
Travel-lightA BCD that dries between dives and folds into a backpack. For the diver who lands at HKT with carry-on only.
Best valueUnder 3 kg, folds in half, and has never let us down on a longtail. The rational travel BCD.
The one thing you should never rent. Fit is everything.
Widest viewWhale sharks at Richelieu Rock go past fast. The Paragon's field of view is the difference between seeing it and seeing its tail.
Best sealThe skirt that fits faces other masks leak on. Low volume, quick to clear, no fuss.
Current at Koh Tachai does not negotiate.
Current fighterWhen Koh Tachai's current runs, you want the fins that got us back to the line. Also the ones that look like a bird.
ClassicThe fin every rental shop in Chalong owns for a reason. Buy your own pair and stop guessing sizes.
29 °C water. Thin suits, natural rubber, fast-drying.
Warm water29 °C water doesn't need neoprene. Thermocline is warm enough for four dives a day and dries on the deck rail.
Night divesFor the fourth dive of the day and the night dive after it, a 3 mm front-zip is the sweet spot.
Whale sharks, mantas, clownfish. Prove it.
Most boughtThe camera on every wrist at Racha Yai. Add a red filter for anything below 10 m.
Permanently sealedNothing to flood. Sealed at the factory, so the only thing you think about at Anemone Reef is the clownfish.
Torches, SMBs, and the bag that carries it all.
Night diveBright enough to find the cuttlefish, small enough to live in a BCD pocket all trip.
EssentialDrift dives at Koh Bon end in the blue. Every guide will ask if you have one. Have one.
Carry-onFits a full travel kit (Travelight, MK25, Quattros) and still goes in the overhead on the Bangkok hop.
