Drifting kelp paddies offshore are floating fish magnets - yellowtail and dorado work the up-current side, bluefin tuna sit in the down-current shadow. How to spot a productive paddy, follow the current line to find more, and approach without spooking the fish.

Restaurant-quality sashimi from a spearfishing trip starts on the back of the boat, not in your kitchen. The on-water processing protocol that lets you drive home stress-free with sushi-grade fish ready to fillet and serve.

Leopard grouper - cabrilla - are one of the most consistently catchable spearfishing targets in the Sea of Cortez. How to identify them, where they hold, and how to take them efficiently.

Moon phases drive tides, fish behavior, and feeding patterns. How divers can use the new moon, full moon, and quarter moons to plan productive spearfishing days.

The thermocline is where warm surface water meets cold deeper water - and where many predator species stage to feed. How to find it, what fish hold there, and how to hunt them.

Red tide kills viz, can make you sick, and changes where fish hold. How to spot it, when it's safe to dive, and what to do if you encounter a bloom mid-trip.

Negative pressure dives let you train deep-water adaptation in a swimming pool. How they work, when to use them, and how to add them to your training without the depth risk.

Hyperventilating before a freedive feels like it helps. It actually masks the urge to breathe and dramatically increases blackout risk. Here's the science and the safer alternative.

The mammalian dive reflex is the autonomic adaptation that lets humans dive deep on a single breath. How it works, how to train it, and why it matters for spearfishing safety and performance.

Why Iki-jime is so much better for your fish than just standard bleeding?

Trachea squeeze is the freediving injury most often mistaken for lung squeeze. Different bleeding pattern, different cause, different recovery. Here's how to spot it and prevent it.

Lung squeeze is the most-feared injury in deep freediving. Learn the warning signs, what causes it, how to recover, and how to train so it never happens to you.

Building your Spearfishing gear over time. A 12-month gear roadmap

A complete guide to spearfishing Guam, Saipan, Tinian, and Rota — the CHamoru tokcha tradition, target species, regulations, conditions, and how to plan a Western Pacific trip on US soil.

Divers' spear gun floating by itself after diver blocks out.

Don't be that guy. Don't post pictures that expose spots.

A practical guide to spearfishing depth: typical hunting ranges by experience level, what actually limits your depth, equalization techniques, safety protocols, and how to build up safely without blowing an ear or lung.

Speargun bands are the engine of your gun. Every bit of power you put into a shaft comes from how well your bands store and release energy. And yet, bands are also the most commonly neglected component on any setup. Divers will spend $800 on a gun, $200 on a slip tip and shaft, and then run the same pair of tired bands for three seasons until they snap on a shot at a personal-best fish. This guide covers how to know when to replace bands, what to buy, how to install them corr

Understanding the different types and of roller spearguns

Most divers blow shots by moving too fast. The craft of hunting fish is built on slow approach, patient waiting, and a smooth trigger. Here is how to stalk calico, sheephead, white sea bass, halibut, and yellowtail in California waters.
