Flying After Diving: Where 12 and 18 Hours Actually Came From

The numbers every diver recites are not arbitrary and they are not a safety margin invented by lawyers. They come from a specific set of chamber trials, and knowing their limits tells you when to wait longer.

PADI, SSI, NAUI, IANTD or GUE: Which Certification Actually Matters

The agencies argue endlessly and the accident data barely distinguishes between them. Here is what genuinely differs, what does not, and the questions to ask a dive centre before you pay.

Freediving in the UAE: Where to Train When the Sea Is 34C

The east coast has the depth, the Gulf side has the pools, and summer changes the answer entirely. A practical guide to training here across the year rather than flying to Dahab every time.

The Summer's Diving Deaths Have More in Common Than the Coverage Suggests

A cave in the Maldives, a lake in Germany, an inlet in Florida, a tuna farm off Malta. Four very different events, and a short list of factors that shows up in nearly all of them.

Lung Squeeze: The Freediving Injury That Comes From Trying Too Hard

Coughing pink after a deep dive is not something to shrug off. Squeeze happens when tissue cannot keep up with pressure, and the usual causes are tension, forcing equalisation and pushing depth too fast.

GUE: The Agency That Will Fail You, and Thinks That Is the Point

Global Underwater Explorers standardises equipment, teaches in teams, tests fitness, and hands out provisional passes rather than certificates. It is the most divisive system in diving, and the most internally consistent.

Entanglement Is a Skill Problem, Not a Knife Problem

Most divers carry something sharp and have never once deployed it underwater. The gap between owning a cutting tool and being able to use one in the dark, with one hand, is where people die.

IANTD: The Agency That Made Nitrox Respectable

In the late 1980s, teaching recreational divers to breathe enriched air was close to heresy. IANTD taught it anyway, then built the trimix and rebreather syllabi much of technical diving still runs on.

How Diving Accidents Are Actually Analysed: The Four Links in the Chain

Almost every fatality report ends with drowning, which tells you nothing. Investigators use a four-part chain instead: trigger, disabling agent, disabling injury, cause of death. Here is how to read one.

SSI: The Dive Centre Is the Unit, Not the Instructor

Scuba Schools International built its model around the store rather than the individual teacher, gave its digital learning away, and quietly became the main alternative to PADI in most of the world.

Three Months After the Maldives Cave Deaths: What Has Actually Changed

Five Italian divers and a Maldivian rescuer died in May. A manslaughter file is open in Rome, a liveaboard lost its permit, and the Maldives is writing technical diving law. A follow-up assessment.

NAUI: The Agency That Lets the Instructor Decide

Older than PADI, structured as a non-profit membership association, and built on a principle almost nobody else uses: the instructor may exceed the standards, and is expected to.

Fish Farm Diving Keeps Killing Divers. The Reasons Are Boringly Consistent

Malta, Chile, Norway, Scotland. Different species and different regulators, the same short list of causes: entanglement, working alone, depth creep, and a job nobody classified as commercial diving.

PADI, Explained Properly: What the Standards Require and What They Do Not

The world's largest training agency is also the most argued about. Setting the snobbery aside, here is what a PADI course actually mandates, where the flexibility sits, and what the card does not cover.

DAN's Safety Guidance, Condensed: What the Research Body Actually Recommends

Divers Alert Network is not a training agency and issues no certifications. It collects the injury data, then publishes guidance based on it. Here is that guidance, in the order it matters.

Can You Get the Bends From Freediving? Yes, and Here Is How

The old assumption was that one breath cannot load enough nitrogen to matter. Repetitive deep dives with short surface intervals disprove it, and the divers it happens to are usually working, not competing.

A Diver Died at a Malta Tuna Farm. Investigators Suspect a 60kg Fish

CO2 and O2 Tables: The Dry Training That Actually Moves Your Breath-Hold

Two tables, two different adaptations, and a hard rule about where you do them. One trains tolerance to discomfort, the other trains efficiency at low oxygen, and confusing them wastes weeks.

Freediving Weights: The Setting That Decides Whether a Dive Is Safe

Overweighting is the most common equipment error in freediving and the one with the worst failure mode. The rule is simple: neutral at ten metres, positive above it, and the surface is where it matters.

Static Apnea: How People Hold Their Breath for Eleven Minutes

The records look impossible until you learn what the body does when the face hits cold water. Most of the gain is physiological adaptation and relaxation, not lung size, and one record category is not comparable to the others.
