Interactive scuba gear field guide · Edition 01
Seven pieces of life-support equipment, taken apart in interactive 3D. Open any piece: see how it is built, watch the physics it fights, and learn why every variation exists.

Every item covers for the others' limits. The tank cannot feed you without the regulator; the BCD cannot trim you without knowing the suit's lift. Learn them as a system, not a shopping list.
Every chapter opens into
Your entire atmosphere, compressed into a backpack.
Working pressure200–300 barTwo stages of physics that turn 207 bar into a breath.
Stage 1 output9.5 bar over ambientA wearable balloon that makes you weightless on command.
Lift capacity10–25 kgA pocket of air that gives your eyes back their focus.
LensTempered glassTurning leg muscle into thrust, efficiently, for an hour.
Cruise speed~0.4 m/s (0.8 kt)Foam full of bubbles, fighting the water’s heat theft.
Thickness3 / 5 / 7 mmA math cop on your wrist, tracking invisible nitrogen.
SamplingEvery 1–5 sEach chapter is one instrument: what it is made of, the four steps it performs, the two laws it obeys, and the choice you will eventually make.
Reading that a regulator drops pressure in two stages is forgettable. Dragging a slider and watching the intermediate pressure hold at 9.5 bar over ambient is not. Every concept here is something you move, not something you memorise.
Boyle, Archimedes, Dalton, Henry: the equipment only makes sense through the physics it fights. Every chapter names the law, states the number, and shows the assumption behind it.
Expensive kit does not fix bad decisions. Every chapter ends with what actually hurts divers: the failure modes, the trade-offs, and the response that works.
