Is scuba diving safe? Honest answer with the numbers

In one paragraph

Recreational scuba diving has a fatality rate of roughly **0.5 to 1.2 deaths per 100,000 dives**, per [DAN Annual Diving Reports](https://dan.org/research-reports/publication-library/). For context, that's comparable to motorcycling and lower than skydiving. The leading cause of dive fatalities is cardiovascular events (often pre-existing conditions), not equipment failure or training gaps. Within recreational limits with current training, scuba is statistically a low-risk outdoor activity.

What the actual risks are — and what training mitigates

The four mechanism types behind dive incidents, in order of frequency: **(1) cardiovascular events** — pre-existing conditions exacerbated by exertion; mitigated by an honest medical questionnaire before certification, **(2) drowning** — usually triggered by panic; mitigated by buoyancy training and the "stop, breathe, think, act" reflex drilled into Open Water, **(3) decompression illness** — from breaking ascent rules; mitigated by dive computers and conservative profile planning, **(4) arterial gas embolism** — from holding your breath on ascent; the first rule every diver learns is "never hold your breath".

Why Gili Air is statistically safer than many other Indonesia sites

Three structural factors: **shallow training depths** — 12 m for Basic Diver, 18 m for Open Water, so no decompression-stop risk at any time during training, **mild currents** — Gili reefs have current ranges of 1-3 (on a 1-5 scale) on most sites, vs Komodo or Penida where 4-5 is common, and **short boat distances** — every site is 5–15 minutes from shore, so emergency surface support is always close. We carry oxygen and an AED on every boat; nearest decompression chamber is in Bali (90 minutes by fast boat + helicopter). Documented in our standard operating procedures.

Common questions

What's the dive insurance situation?

We strongly recommend DAN (Divers Alert Network) coverage — annual cost is ~$50-90, and it covers chamber treatment, evacuation, and lost-gear claims worldwide. Most general travel insurance excludes scuba beyond ~30 m or excludes "training" entirely. Read your policy before flying. We can sell DAN cover at the centre as a single-trip add-on if you arrive without it.

How often does Gili Air Divers have incidents?

In 14 years operating (2011–present), we have had no fatalities and a handful of minor decompression treatments — all resolved without lasting effects. Industry incident rate is roughly 1 in 50,000 dives; we run ~25,000 dives a year. We follow SSI standard operating procedures plus a self-imposed 4:1 student:instructor ratio (the WRSTC industry maximum is 8:1).
