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.
Freediving for lobster
Method · Last reviewed 2026-08-12
Hunting lobster on breath-hold by reaching into holes — a mainstream summer activity in several parts of the world, and one of the more dangerous positions in the sport.
Safety
Shallow water blackout and breath-hold loss of consciousness — Can cause serious injury or death
A diver head-down in a hole, hands occupied, at the end of a breath-hold and unwilling to leave an animal, stays past the point at which they should have surfaced. Blackout gives no warning and the diver does not know it is coming.
What reduces it: Formal freediving instruction before hunting on breath-hold. A competent buddy on one-up-one-down for every dive. Conservative dive times well inside your training, and a standing decision to leave any animal rather than extend a dive.
Entanglement — Can cause serious injury or death
Lobster ground is rocky and frequently holds lost pot rope, netting and line. A diver reaching into a crevice can be snagged in a place they cannot see, at the end of a breath-hold.
What reduces it: Carry a cutting tool you can reach with either hand and have been shown how to use. Never enter a space you cannot reverse out of. Your buddy on the surface is the reason somebody knows where you are.
Encounters with marine life — Can cause injury needing treatment
A hand entering an unseen hole may find a moray, a conger or something else occupying it, and the bite is to a hand the diver cannot immediately withdraw.
What reduces it: Look before reaching wherever possible. Use a snare or tickle stick rather than a bare hand on unfamiliar ground, and wear gloves where local rules permit them.
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.
- Never hyperventilate before a breath-hold. It delays the urge to breathe without adding oxygen, which is precisely the mechanism behind shallow water blackout.
- Tell somebody where you are going and when you expect to be back.
- Carry a charged phone in a waterproof case, or another means of calling for help.
Freediving for lobster is spearfishing's near neighbour and is practised by many of the same people, in the same water, with much of the same equipment and none of the same tackle. The diver locates an animal by its antennae protruding from a hole, approaches, and takes it by hand or with a snare or tickle stick.
It deserves to be treated separately for one reason: the body position. A spearfisher takes a shot with the head up and the body free. A lobster diver is head-down in a hole at the end of a dive, with both hands occupied, unable to see the surface, holding an animal that is bracing against the rock and actively resisting. Every element of that increases the time on the bottom and the incentive to stay one more second, and the urge to stay is exactly what a blackout feels like from the inside — which is to say, like nothing at all.
So the safety posture here is stricter rather than looser than for spearfishing. Get proper freediving instruction before hunting on breath-hold. Dive with a competent buddy, one up and one down, every dive. Carry a cutting tool reachable with either hand, because lobster ground holds lost pot rope. And leave the animal. There is no lobster worth a breath-hold, and the decision to surface without it is the skill worth having.
The fishery is licensed or permit-controlled almost everywhere it exists, frequently with a season, a size limit measured on the carapace, a prohibition on taking berried or v-notched females, and rules on what may be carried in the water.
What it is
Hunting lobster on breath-hold by locating an animal in a crevice — usually by the antennae protruding from it — and taking it by hand or with a snare or tickle stick. It is practised by many of the same people, in the same water and with much of the same equipment as spearfishing, and it deserves separate treatment because the body position is far more dangerous.
How it works
The diver descends, searches structure systematically rather than covering distance, and works the animal out of its hold rather than pulling against it — a lobster braces with its legs and tail and a straight pull loses limbs and the animal.
What makes this distinct from spearfishing is what the diver's body is doing. A spearfisher takes a shot head-up with the body free. A lobster diver is head-down in a hole at the end of a dive, both hands occupied, unable to see the surface, holding something that is actively resisting. Every element of that lengthens the dive and increases the incentive to stay one more second — and the urge to stay is exactly what a blackout feels like from the inside, which is to say like nothing at all.
What it is for
It reaches animals that pots cannot: individuals holding ground where gear cannot be set, and in areas where potting is restricted but hand-taking is permitted. It is also entirely selective — the diver sees the animal, its size and whether it is berried or notched, before deciding to take it, which no baited trap can do.
Setting it up
- Formal freediving instruction before hunting on breath-hold, not after. This is a training prerequisite rather than a recommendation.
- A competent buddy and a one-up-one-down rotation on every single dive.
- A cutting tool reachable with either hand, because lobster ground holds lost pot rope and netting.
- A marked surface float and line, so boat traffic knows a diver is below.
- A standing decision, made on the surface, to leave any animal rather than extend a dive for it.
Advantages
- Completely selective: size, sex and the presence of eggs or a v-notch are all visible before the decision to take is made.
- It leaves no gear in the water, so it creates no ghost fishing.
- It reaches ground that pots cannot be set on.
Limitations
- It is depth- and breath-limited, and the limit is personal, varies day to day, and shrinks in cold water.
- Conditions rule it out often: surge, poor visibility and current all turn a controlled approach into an uncontrolled one.
- It cannot be done safely alone, which is a hard constraint rather than a preference.
Conditions
Suits rocky and reef ground in clear, calm water within comfortable breath-hold depth, in the season and jurisdiction where it is permitted. Ruled out by surge, poor visibility and current. Cold water shortens breath-hold and degrades judgement faster than divers expect, and it does so before they notice.
Common mistakes
- Diving without formal freediving training. Breath-hold blackout is silent, gives no warning, and is not something reading prepares anybody for.
- Diving alone, or diving with a partner who is not watching. One up, one down, every dive, is the whole of the buddy system and it is what turns an incident into a recovery.
- Extending a dive to get an animal out of a hole. This is the single mechanism behind most incidents in the discipline. Leave it and come back down.
- Entering a space you cannot back out of, or working into gear and rope without a cutting tool you can reach with either hand.
- Assuming the local rules match the last place you dived. Season, size, berried and notched females, permitted gear and permitted areas all differ, and all change.
