The PROTECT package treats drowning as a systems failure involving childcare, transport, infrastructure, rescue and climate preparation, not a single bad choice.

The world's deepest pool holds 14 million litres at a constant 30C, with a sunken city at the bottom. What it removes from diving turns out to be the interesting part.

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.

Deep water a short swim from shore, no boat, no current and warm all year. Dahab's geography explains its status, and the same geography is why the Blue Hole has the reputation it has.

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 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.

Manufacturers compete on brightness because it is a single large number. Underwater, beam angle, burn time at full output and the switch you can operate in gloves decide whether a torch is any good.

A breathing machine pressurised to 198 feet of seawater measures the work it takes to pull air through a regulator. Almost nothing you read online involves one, and the difference is the whole review.

Safety divers, counterballast lines and strict medical protocol turned a high risk sport into one of the most closely supervised in the water.
