The Science of Dive Computers: Algorithms, Gradient Factors, and Why Different Computers Give Different Deco Advice Ask five divers what computer they dive with and you’ll get five passionate answers. Ask those same divers what algorithm their .. Read More

Why BCD Design Matters: The Science Behind Lift, Trim, Air Cell Geometry & Diver Control Divers tend to lump all BCDs into the same category: “something that holds the tank and helps me float.” That’s like saying all cars are th.. Read More

How Your Regulator Actually Works: The Hidden Engineering That Keeps You Breathing at Depth Divers trust their regulators with their lives, but very few actually understand how a regulator makes it possible to breathe underwater. A reg isn&.. Read More

Breathing Underwater: How Your Diaphragm, CO₂ Sensors, and Lung Mechanics Change at Depth Breathing underwater seems simple: inhale from the regulator, exhale into the water, repeat. Most divers never go deeper than that mentally. But the physiolog.. Read More

Thermal Stress Underwater: How Cold Changes Your Physiology, Gas Loading, and DCS Risk Divers love to talk about gear, buoyancy, trim, SAC rates, and decompression models — but the most powerful variable in diving physiology isn’t on a co.. Read More

CO₂ Retention: The Silent Killer of Diving Performance (and Why It Causes Panic Underwater) Divers obsess over nitrogen, oxygen, PPO₂ limits, gas narcosis, and deco schedules — but the gas that causes the mostreal-world problems underw.. Read More

Oxygen Toxicity: What PPO₂ Really Does Inside Your Cells (and Why It Matters Even for Recreational Divers) Divers are taught that “too much oxygen is dangerous,” but very few understand why. Oxygen is literally the molecule that ke.. Read More
