▚ THE MAP ▚
Knowledge Hubs
Eight through-lines that tie the reviews, decision pages, and glossary together — start here when you want to understand a subject, not just buy one thing.
Dive Computer Algorithms
Why two computers on the same dive show different NDLs, what gradient factors actually adjust, and how conservative firmware changes a liveaboard week. The math is published; the temperaments are not.
Regulator Anatomy
First stage to exhaust tee: piston vs diaphragm architecture, intermediate pressure, port layouts, why the octo is yellow, and what a service bench actually replaces on the schedule your manual sets.
Buoyancy & Trim
The flat, quiet, no-silt ideal — and the gear decisions that make it easier or harder: lift capacity, weight placement, wing vs jacket geometry, and the surface checks that calibrate it all.
Exposure Protection
Millimetres against temperature bands, seam construction that actually keeps water out, hoods as force multipliers, and the point where the drysuit conversation stops being hypothetical.
Air Consumption
SAC and RMV without the spreadsheet dread: how to measure with any SPG, what actually moves the number (hint: relaxation beats fitness), and the air-integration question priced honestly.
Gear Service & Care
Rinse, dry, store, service on schedule — the maintenance layer that decides whether gear lasts three seasons or fifteen. Includes the service-interval logic behind our pre-dive tool.
Dive Safety Basics
The vocabulary of staying comfortable: safety stops, surface intervals, no-fly windows, buddy checks, and the signaling gear that makes you findable. Gear context only — training owns the procedures, and we link out where it does.
Nitrox & Gas
The green-and-yellow band explained: MOD, ppO2, analyzing every fill, and whether enriched air earns its surcharge for the way you actually dive.
