Guides, tips, and stories from our divers

29-Cent Shark Satay From a Village That Still Hunts Sharks

In Tanjung Luar, wooden boats return from 20-day voyages with holds full of sharks. Twenty kilometres inland, their meat becomes satay sold for pocket change.

27 Dolphins, One Cargo Plane, and a Cold War Ghost Story

In 2000, a Soviet trainer flew 27 war-trained dolphins to Iran. Twenty-six years later, they resurfaced — in a Pentagon briefing about kamikaze dolphins.

The Net Keeps Fishing After the Fisher Leaves

Abandoned fishing nets kill 300 marine animals a year in Thai waters — and they never stop catching. Divers are pulling them off the reefs.

Your Tank’s Test Date Expired — Can You Still Dive It?

Three stamps on every cylinder neck decide whether you dive or walk. What they mean, what Thai law requires, and what happens when the date runs out.

64 Faces in a Database: How Koh Tao Tracks Every Hawksbill

Koh Tao's turtle database holds 64 hawksbill faces, each mapped by unique scale patterns. The same turtles return to the same reef ledges year after year.

The Thai Navy cut holes through every deck of a WWII landing craft and sank it off Koh Phai. Twenty-three years later, it is Pattaya's best penetration wreck.

Five Signals That Should End a Dive Before the Computer Does

Your computer tracks depth and time — not your breathing rate, your buddy's panic, or the current building behind you. Five warnings come first.

Lembeh Strait packs nine frogfish species, a dozen octopus varieties, and hundreds of rare critters onto 16 km of volcanic black sand — here is what lives there.

Between dives off Phuket, a compact tin-mining quarter serves Michelin-recognised noodles for 50 baht and hides 200 years of Hokkien architecture on seven walkable streets.

2 km from Phi Phi, a Reef That Only GPS Can Find

Hin Klai sits 6 metres below the surface with no marker, no buoy, and more barrel sponges than any reef near Koh Lanta. Here is what hides between the boulders.

Why Cave Divers Fly to Russia for 5 km of White Silence

Orda Cave hides 5 km of white gypsum passages under the Urals — 46-metre visibility, 4°C water, and walls older than dinosaurs.

One Kick Snaps 19 Corals an Hour, the Other Glides Past

Research counted 19 coral breaks per hour from careless fins. The frog kick changes that equation — here is how it evolves from OW to cave level.

The O₂ Kit Every Dive Boat Carries but Nobody Practises

Only 24% of injured divers receive oxygen first aid. The kit sits on every boat — here's the red-flag checklist and four-step drill that makes it useful.

Thai Liveaboards at $125 a Night — and the Gap Is Closing

Thailand's Similan fleet still runs at half the nightly rate of Red Sea boats — but fuel surcharges and booming demand say it won't last.

The Ice Crystal That Empties Your Tank at 35 Metres

A single ice crystal can jam your second stage open and drain a full tank in minutes. The physics, the in-water fix, and the hardware that fights back.

Three hundred chevron barracuda form a rotating column taller than the pinnacle itself. The physics behind the Gulf's most reliable vortex involves selfishness, wake energy, and one isolated rock.

Why Whale Sharks Return to Hin Muang's 60-Metre Purple Wall

Thailand's deepest dive wall drops 60 m into the Andaman Sea — draped in purple soft coral and visited by whale sharks every February through April.

Darwin's Arch Lost Its Bridge — the Sharks Never Noticed

The arch fell in 2021 — but 200 hammerheads still circle Darwin's pillars every dawn. Currents, cleaning stations, and magnetic rock explain why.

Thailand Had 280 Dugongs — Now Fewer Than 100 Survive

Thailand's dugong count dropped from 280 to under 100 in three years. Seagrass collapse — not boats, not nets — is starving the Andaman's last herds.

7 Mistakes Every New Diver Makes When Nobody Is Watching

From over-weighting to skipping buddy checks, these seven post-certification mistakes hit with clockwork regularity — and every one is fixable before you get wet.

Your CPR Card Means Nothing on a Longtail in Open Swell

Classroom CPR assumes solid ground. Thai dive boats offer wet bamboo and open swell. The physics change — here is how to adapt and what kit to demand.

Why a Maldives Week Costs More Than Two Similan Safaris

A budget Maldives liveaboard starts at $1,200 for seven nights — roughly what two Similan safaris cost combined. The mantas are the same genus. The invoice is not.

The 3-Second Mistake That Drags Divers to the Surface

A slack loop catches your valve post. The SMB rockets up. You follow — unless you know the drill that stops it cold.

One Missing Sugar Is Why Anemones Don't Eat Their Clownfish

Clownfish mucus lacks one sugar that triggers anemone stings — a 2025 study cracked the mechanism. Plus sex changes, matchmaking rules, and Thai species.

Why 94 Species Choose Racha Yai's Most Trampled Sand

Researchers counted 94 fish species at Racha Yai Island — most within sight of the sand patch where hundreds of diving students kneel every single week.

A single anchor chain destroys decades of coral growth in seconds. Here is the science behind the damage and the low-cost fix Thailand's marine parks are racing to install.

5 Advanced Diver Habits That Backfire in Rescue Training

The jump from Advanced to Rescue is not about depth — it is about performance under stress. Five habits from AOW that will trip you up, and how to fix them.
