The Scuba Safety Stop: How Long, How Deep, and Why
Three minutes at five metres ends almost every recreational dive. Where the stop came from, what the bubble studies show and do not show, when agencies treat it as required, and how to weight and plan gas so you can hold it.

Sixteen Lines: The New Dive Kit Logo and Where It Comes From
A new icon for v3.0.0: sixteen bars, one per ZH-L16C compartment, weighted by half-time. How it is built, why the logarithm, and what we tried before it.

500 psi Is Not 50 bar: Imperial and Metric Conventions in Diving
A 500 psi reserve and a 50 bar reserve differ by 225 psi, and neither depends on the cylinder you carry. This article covers the reserve, rock bottom and the other conventions that change between unit systems, with the numbers.

Bühlmann, VPM, RGBM and the Rest: How Decompression Algorithms Work, and What the Evidence Says
Dive computers and planners run ZHL-16C, RGBM or VPM-B. This article covers the history, the mechanics and the testing record of each, why no algorithm can be shown to be best, and newer models few divers know.

Same Dive, Different Stops: Why Your Plan and Your Buddy's Don't Match
Two divers plan the same 45 m dive and surface 12 minutes apart, and both plans follow their own settings. This article explains how two ZHL-16C planners can disagree, which conventions differ between them, which settings move a schedule and by how much, and what to compare before the dive.

What Is Decompression, and Why Do Divers Plan for It?
The slow ascent, the safety stop and the no-deco limit all manage one problem you cannot feel: dissolved gas. This article explains decompression, how divers learned to manage it, and where to learn more.

SAC, RMV, and SRMV: What Your Breathing Rate Is Actually Called
Divers use SAC and RMV for different things, often with different units. This article defines the terms from the medical definition up, shows the maths, and explains why Dive Kit uses SRMV.

What “AL80” Actually Means: Cylinder Capacity, Explained
An AL80 holds about 77 cubic feet of gas, not 80. This article explains how cylinders are sized and named: water capacity and free-gas capacity, the maths, and how real-gas behaviour changes the number on the label.

Unpacking Gradient Factors
Gradient factors are two numbers that set how a planner or dive computer brings you up. They date from the late 1990s, and recent research changed what 'conservative' means. This article explains the trade-off so you can choose your own setting.
