Before you spearfish — this comes first
- Get proper instruction before you spearfish. A recognised freediving or spearfishing course teaches the things that actually kill people in this sport, and reading about them is not the same as being taught them.
- Dive with a buddy, and dive one up, one down — one diver in the water, one on the surface watching them, every dive. A breath-hold blackout is silent and gives no warning; a watching buddy is the difference between an incident and a fatality.
- Stay inside your own training and experience. Depth and breath-hold times are personal, they change day to day, and nobody else's numbers apply to you.
- Understand the conditions before you enter the water: visibility, current, swell, tide, boat traffic and your exit. Conditions decide whether a dive is reasonable far more often than skill does.
- Use equipment you have been shown how to use, check it before every session, and be visible — a marked float and line are how boat traffic knows you are there.
- Never extend a dive for a fish. No catch is worth pushing a breath-hold, and the urge to take one more second is exactly what a blackout feels like from the inside — which is to say, like nothing at all.
Pole spears and Hawaiian slings
Tackle · Last reviewed 2026-08-10
The simplest spearfishing tools: a shaft powered by a rubber loop held under tension by the hand, or launched free from a handheld track.
Safety
Entanglement — Can cause injury needing treatment
A pole spear is under tension in the diver's own hand, and a slip or a premature release drives the shaft somewhere unintended at very close range. A Hawaiian sling releases a free shaft, which then has to be recovered and which travels further than people expect.
What reduces it: Load only in the water and point the shaft away from every person at all times, including when you believe it is unloaded. Know where your buddy is before you tension anything. With a sling, never shoot towards open water where the shaft's travel cannot be accounted for.
Shallow water blackout and breath-hold loss of consciousness — Can cause serious injury or death
Short range and slow reloading push a diver to get closer and stay longer, which extends breath-holds. The tool is simple; the physiology is not.
What reduces it: Dive time decided on the surface and kept to. One up, one down. Surface and repeat rather than waiting for one more approach.
Precautions that always apply here
- Never spearfish or freedive alone.
- Dive one up, one down: one diver down, one on the surface actively watching, every single dive.
A pole spear is a shaft with a rubber loop at the back. The diver stretches the loop, grips the shaft under tension, and releases it to drive the shaft forward — the whole tool is one piece and there is nothing to reload but your hand.
A Hawaiian sling is a different thing that is often confused with it: a separate handheld tube or track through which a free shaft is launched by a stretched band, like a bow. The shaft leaves the sling entirely, which is why slings are prohibited or restricted in a number of places where they are considered too close to a projectile weapon.
Both matter more than their simplicity suggests. Range is short and reloading is slow, which pushes a diver towards getting close and taking one considered shot — and that produces more selective, more thoughtful hunting than a powerful gun does. In several jurisdictions they are also the only equipment permitted, which makes them the entry point rather than a compromise.

What it does
Stores energy in a stretched rubber loop and releases it to drive a shaft over a very short distance. A pole spear keeps the shaft attached to the diver's hand throughout; a Hawaiian sling releases the shaft entirely, which is a materially different thing legally and in terms of what happens to a missed shot.
How to choose one
- Match length to the environment: short in confined rock and holes, longer in open reef where range helps.
- Choose the tip for the species and the ground — a paralyser tip for small fish, a single barbed or slip tip for larger ones.
- Check what is permitted where you intend to dive before buying, because slings in particular are restricted in a number of places.
- A stiffer shaft loses less energy but is heavier to swim with; the trade is real and personal.
- Simplicity is the feature. A tool with nothing to go wrong is worth a great deal in the water.
What the numbers mean
LENGTH is quoted in feet or metres and typically runs from about 1.2 m to over 2 m; longer means more range and more stored energy but more awkward handling. BAND or LOOP diameter and length determine the power and how far the diver must stretch. SHAFT DIAMETER, in millimetres, trades penetration against speed. TIP TYPE — paralyser, single barb, slip tip — is the part that decides what happens after the shot. Note that the loop is a consumable: rubber perishes with ultraviolet light, salt and age.
Care, and how it fails
The rubber is what fails, and it fails suddenly. Rinse in fresh water, store out of sunlight, and replace on a schedule rather than when it breaks — a loop that parts under full stretch does so with the diver's hand at the point of maximum tension. Check the shaft for bends and the tip for damage after every session, and check that a slip tip's mechanism actually still slips.
Why a pole spear is a different activity rather than a cheaper one
A pole spear is usually presented as the beginner's speargun. It is better understood as a shorter-range, quieter, more demanding way of hunting that some very experienced divers prefer.
WHAT IT IS. A shaft with a rubber loop at the butt. The diver stretches the loop along the arm, holds the shaft under tension against the palm, and releases. Energy comes from the diver's own arm and the loop, range is a metre or two, and there is no trigger, no safety and no mechanism.
WHAT THAT BUYS. Simplicity that cannot fail in a way that hurts anybody: there is no loaded weapon in the water, nothing to discharge accidentally, and nothing to maintain beyond a rubber loop and a tip. It is quiet, which matters on pressured ground. It travels easily. And it is legal in a number of places where a speargun is not, which is a fact worth checking rather than assuming in either direction.
WHAT IT COSTS. Range. A pole spear demands the diver get within touching distance of the fish, which means the approach — the aspetto wait, the slow drift, reading how the fish is responding — is the entire skill rather than a preliminary to it. That is why it is simultaneously the sensible first purchase and a deliberate choice made by people who could afford anything.
AND IT CHANGES THE QUARRY. Small and moderate fish in structure, crustaceans and cephalopods where taking them is lawful, and fish that can be approached. It is not the tool for anything that runs.
THE SAFETY FRAMING IS DIFFERENT RATHER THAN ABSENT. There is no accidental discharge, and the diver is still a breath-hold diver: blackout, buddy procedure, weighting, entanglement in a stringer or float line and the temptation to extend a dive for a fish all apply exactly as they do with a gun. A simpler weapon does not simplify the physiology.
WHAT MAY BE USED WHERE IS NOT ON THIS PAGE. Pole spears, spearguns, and both together are permitted, restricted or prohibited differently between neighbouring administrations, and the authority for the water is the only source.

Instead of this
- Speargun or pole spear to start withA pole spear demands a better approach and forgives less; a gun is more capable and more to manage.
- SpeargunsBoth propel a shaft a short distance underwater. One has a trigger, a safety and a maintenance schedule; the other has a rubber loop and a hand, and cannot discharge accidentally.
- Speargun power systemsThe two ends of the same activity. A gun buys range and mechanism; a pole spear removes both and makes the approach the entire skill, which is why it is simultaneously the sensible first purchase and a deliberate choice by experienced divers.

Check the rules before you fish
Fishing laws, bylaws, access rules, seasons, bait restrictions and permitted methods vary by location and can change. Check the current rules from the relevant authority and the water you intend to fish before fishing.
Check with:
- Current national or regional law for where you are fishing
- Current local bylaws
- The relevant fisheries authority
- The landowner, club or fishery whose water it is
- Any restrictions specific to the species or the method you intend to use
