Below about 15 degrees a thick wetsuit keeps a diver alive but not warm, and cold is a safety problem before it is a comfort one: it thickens judgment, wastes gas and makes the hands useless. The drysuit is a different way of diving, not a thicker suit.

A wetsuit that fits badly is a wetsuit of any thickness that does not work. Match millimetres to the water, check the fit at the neck, the small of the back and the wrists, and know which neoprene you are paying for.

Submersion triggers an ancient reflex that slows the heart, redirects blood, and quietly reshapes what a trained freediver's body can survive underwater.

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.

Divers who silt the bottom, burn through gas, struggle to hold a safety stop and finish cold usually share one cause. They are carrying too much lead, and every other symptom follows from it.

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.

Descent equalisation is drilled into every open water student. Reverse block, where expanding gas cannot escape the middle ear or sinus on ascent, gets a sentence in the manual and is considerably harder to manage.

Two men and a woman surfaced from a dive at Canyon Reef, found no boat, and were carried kilometres out. Whether lost divers are found has surprisingly little to do with the search itself.

PFO, asthma, diabetes and certain medications can all change whether diving is safe. Here is why the medical questionnaire before a course matters.

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.

Most ear injuries in scuba happen shallow, on descent, to divers who waited for pain before they equalised. The technique matters less than the timing, and the timing starts on the surface.

Spearfishing shares its breath hold physiology with freediving, but a hunting mindset changes the risk calculation entirely, and blackout remains the top cause of death.

The standard aluminium 80 is negatively buoyant full and positively buoyant empty, which is why safety stops go wrong at the end of a dive. Steel behaves differently, and the valve and testing rules differ too.

Dahab's Blue Hole draws freedivers year round for a reason: shore access to real depth, warm water, forgiving conditions and an established training community.

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

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.

Coral is an animal with a skin a few cells thick. The diver who kneels for a photograph, the snorkeller who stands to adjust a mask, and the oxybenzone in a lotion each do damage that the reef cannot repair in a season.

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.

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.

Scuba has real hazards, but recreational diving within training and conditions is a managed-risk activity, not the extreme gamble suggested by rare accident headlines.

A French submarine at 36 metres, a 1939 freighter at 40, and a Victorian battleship far beyond recreational limits. Lebanon's coast is a wreck list before it is a reef.
Aug 6, 2026
Two agencies now certify divers to dive alone, with redundant gas and a long list of prerequisites. The case for it rests on an uncomfortable observation about how often the buddy system already fails in practice.

A woman and her partner, both long-serving members of the European technical community, did not survive an emergency ascent near Ueberlingen on 2 August. The cause is still unknown.

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.

Three minutes at five metres is drilled into every diver and explained to almost none of them. It is not decompression, it is not required, and skipping it is not the emergency people assume.

Finnish cave specialists, Maldivian coast guard divers and DAN Europe medics carried out a coordinated recovery after the Vaavu Atoll cave tragedy.

A rebreather trades noisy bubbles for silent, efficient diving, but it also trades forgiveness for discipline. Here is what changes underwater.
