Spearfishing is the most direct way there is to put dinner on the table — no boat full of gear, no spread of lures, just you, a held breath, and a shot you have to earn. It’s hunting and diving fused into one, and it hooks people hard. But it’s also the saltwater pursuit with the least margin for error. Done right, it’s deeply rewarding and remarkably sustainable. Done carelessly, it’s dangerous. This guide gets you started the right way.
Here’s the Insider’s guide to taking your first shot.
Learn to Freedive First — Spearfishing Comes Second
The single biggest mistake new spearos make is trying to learn to hunt and learn to dive at the same time. Don’t. Get comfortable in the water first. You should be able to relax, descend, hold a calm breath, and move efficiently before you ever add the complication of a spear.
A freediving course is the best money you’ll spend in this sport. You’ll learn proper breathing, how your body responds to depth, how to move with less effort, and — most importantly — how to recognize and avoid the dangers below. Most beginner spearfishing is done on a single breath from the surface, not on scuba (and scuba spearfishing is illegal in many places — more on rules below). Build the diver first. The hunter follows.
The Number One Rule: Never Dive Alone
This is the rule that keeps you alive, so it goes near the top. Always spearfish with a buddy, and use the one-up, one-down system: while one diver is down, the other stays on the surface watching them the entire time, ready to help. You swap on every dive.
The reason is a hazard called shallow-water blackout — a loss of consciousness that can happen near the surface at the end of a breath-hold, often with no warning. A diver experiencing it needs someone right there, immediately. A buddy watching from the surface is the difference between a scary moment and a tragedy. And one hard rule that comes straight out of this: never, ever hyperventilate before a dive to extend your breath-hold. It doesn’t make you safer — it makes blackout more likely.
Know the Rules Before You Get in the Water
Spearfishing is heavily regulated, and the rules exist to keep the fishery healthy. Knowing them isn’t optional — it’s part of being a responsible Insider. Before your first hunt, check your local and state regulations for:
- Licenses and permits. Most places require a saltwater fishing license to spearfish.
- Legal species. Many fish are off-limits to spearing entirely. Only shoot what’s legal in your waters.
- Size and bag limits. The same limits that apply to rod-and-reel anglers apply to you.
- Closed and protected areas. Marine sanctuaries, parks, and certain reefs are no-take zones. Know where you can and can’t hunt.
- Gear restrictions. Some areas restrict spearguns, ban scuba-assisted spearfishing, or limit you to certain methods.
- The dive flag law. You’re legally required to display a dive flag so boats know divers are in the water. This is safety and law in one.
When in doubt, leave it in the water. A clean conscience and a clean record beat any fish.
Start Simple: Your First Gear
You don’t need a six-foot pneumatic speargun to start. Begin with the basics and grow into the rest.
- A pole spear or Hawaiian sling is the ideal starting tool. Short range, simple, and they force you to get close and learn to stalk — which makes you a better hunter for life.
- Mask, snorkel, and fins that fit well. Comfort and a good seal matter more than price.
- A wetsuit appropriate for your water temperature — it keeps you warm, protects your skin, and adds a little buoyancy.
- A weight belt set up so you’re slightly positively buoyant at the surface. You should always float up if you stop swimming.
- A float and dive flag with a float line. Your catch goes on the float, not tied to your body — you don’t want fish blood and struggle attached to you in the water.
Once you’ve got real water time and clean technique, you can graduate to a proper speargun. But a lot of accomplished spearos still love the challenge of a pole spear precisely because it makes you earn every fish.
Hunt Smart: Targets and Technique
For your first outings, fish shallow, clear, calm water where you can see well and stay relaxed. Pick forgiving, abundant, easy-to-identify species that are legal in your area — your local dive shop or spearfishing community can point you to the right beginner targets.
A few fundamentals that put fish on the stringer:
- Identify before you shoot. Never take a shot at a fish you can’t positively identify as legal. If you’re not sure, don’t shoot.
- Aim for the kill zone just behind the gills — a clean, ethical shot that drops the fish fast.
- Move slow and stay calm. Thrashing and chasing spooks everything. Relaxed, quiet divers get close. Many spearos let fish come to them.
- Get your fish secured quickly and onto the float to keep blood and struggle away from your body.
Respect the Ocean and What’s In It
A real spearo is a conservationist. You’re selecting your exact fish, one at a time, with zero bycatch — which makes spearfishing one of the most sustainable ways to harvest, when it’s done responsibly. Honor that. Take only what you’ll eat, leave the breeding-size giants and protected species alone, and be aware that blood in the water can attract sharks — stay alert, keep your catch on the float, and don’t push your luck. The Insiders who last in this sport are the ones who treat the resource with respect.
The Insider Bottom Line
Learn to freedive before you learn to hunt. Never dive alone, never hyperventilate, and always run one-up, one-down. Know your local regulations cold and fly your dive flag. Start with a pole spear in easy water, only shoot what you can identify and legally keep, and take only what you’ll use. Get those right and spearfishing will give you something few pursuits can — the quiet pride of bringing home dinner you earned on a single breath.
Take it slow, take it safe, and take only your shot.
See you on the water.
