I've taught hundreds of beginners to dive. These three mistakes show up every single time — and none of them are about skill.

1. They hold their breath

When something feels off underwater, the panic instinct is to hold your breath and bolt for the surface. That's how you get decompression sickness. Fix: practice slow, continuous exhaling until it's automatic. Drill it in a pool. Make it a reflex before you go deep.

2. They equalize too late

Beginners wait until their ears hurt to equalize. By then you're already behind. The right move: equalize every meter on the descent, before it hurts. Early and often.

3. They skip buoyancy

Most courses rush past this. Bad buoyancy means you're either sinking into coral or popping up uncontrolled. Before anything else, spend 30 minutes holding neutral buoyancy at 5 meters. If you can stay there without effort, you're ready for anything.

None of this requires expensive gear or years of practice — just deliberate focus.
