Spearfishing terminology
Explainer · Last reviewed 2026-08-27
The vocabulary of this discipline is Italian, French, Hawaiian and English at once, because the equipment and the techniques came from different places — and knowing which word belongs to which tradition explains more than a definition does.
Spearfishing terminology is a historical map rather than a glossary, and reading it that way makes it far easier to learn.
THE ITALIAN LAYER covers technique, because the modern recreational discipline was largely codified in the Mediterranean. ASPETTO is the technique of settling on the bottom and waiting for fish to approach. AGGUATO is the stalk into position using ground and cover. Both are used by divers who speak no Italian, and both describe clear water: they are techniques that need visibility on both sides.
THE FRENCH LAYER covers the gun. ARBALÈTE — literally crossbow — is the band-powered speargun, and the word is standard across much of Europe. Italian speakers say FUCILE, meaning rifle. Both metaphors are about the same thing: a stored-energy weapon aimed and released.
THE HAWAIIAN AND PACIFIC LAYER covers the simplest and oldest equipment. The HAWAIIAN SLING is a handheld track or tube with an elastic band that launches a free shaft. The POLE SPEAR is a shaft with an elastic loop held under tension by the hand. Neither is a beginner's speargun; both are current equipment with high selectivity and short range.
THE ENGLISH LAYER covers the parts and the systems, and it is the most literal. FLOPPER — the hinged barb on a shaft that opens after penetration to stop the fish sliding off. SLIP TIP — a detachable point that toggles sideways inside the fish and is used for large ones. WISHBONE — the small loop joining the ends of a rubber band that engages the shaft notch. SHOOTING LINE — the line from gun to shaft. FLOAT LINE — the line from gun or shaft to a surface float. BREAKAWAY — a system in which the shaft separates from the gun so the fish fights the float instead of the diver.
AND A FEW THAT DESCRIBE THE DIVING RATHER THAN THE GEAR. BLUE WATER — hunting pelagic fish in open ocean with no bottom in sight. HOLE HUNTING — searching caves and undercuts. SHORE DIVE — entering and leaving under your own power from land. SAMBA — the informal name for loss of motor control, which is the last warning before blackout and is the one term on this page that is a safety matter rather than a convenience.
What this is called elsewhere
FishingHQ’s headword is the term used in Global.
- Arbalète — Western Europe, Mediterranean
- French for crossbow, and the standard word for a band-powered speargun across much of Europe.
- Fucile — Mediterranean
- Italian, literally rifle. The same object as an arbalète, named after a different weapon.
- Aspetto and agguato — Mediterranean
- The waiting and the stalking techniques. Used internationally in Italian because the techniques travelled with the words.
- Hawaiian sling — Pacific Islands, North America, Caribbean
- A handheld track launching a free shaft. Named for its origin and now used far beyond it.
- Gun — Australia, New Zealand
- Ordinary Australasian usage for a speargun, where elsewhere the longer word is normal.
Where the words differ by country, and where they do not travel
Most of this vocabulary is genuinely international, which is unusual in fishing — an Australian and a Croatian will both say flopper, float line and blue water. Where it varies, the variation is worth knowing.
THE GUN. Arbalète in French and widely in Europe; fucile in Italian; speargun in English; and in Australia and New Zealand simply GUN in ordinary use.
THE SHAFT is a spear or a shaft in English, and the distinction between a SHAFT (fired from a gun) and a SPEAR (a pole spear or hand spear) is not maintained consistently by anybody.
THE FLOAT is a float or a buoy in most English usage; DIVE FLAG refers specifically to the marked flag identifying a diver below, and the required flag design itself differs between countries — the alpha flag internationally, and a different diver-down flag in North America.
WETSUIT TERMS carry an important technical distinction that beginners meet as jargon: OPEN CELL means the inner neoprene surface is uncoated and seals against the skin, which is warmer and more fragile and needs lubricant to put on. CLOSED CELL is lined. This is a real specification difference rather than a brand word.
AND ONE WORD THAT MEANS SOMETHING ELSE ENTIRELY OUTSIDE THE DISCIPLINE. In rod fishing a FLOAT is a bite indicator; in spearfishing it is a surface buoy that is primarily a safety device. FishingHQ carries both, and they are unrelated.
A note on why the safety vocabulary matters more than the rest: a diver who does not know what a samba is may watch one happen and think it is amusing rather than a warning that the next dive could end in blackout.

How this compares
- Fishing terminologyTwo glossaries for two vocabularies that overlap less than a reader expects. A term that is settled in one is frequently absent or contradictory in the other, and that is worth seeing directly.
- Float, bobber and quillA float is a bite indicator in rod fishing and a surface safety buoy in spearfishing. Same word, unrelated objects.
- The Mediterranean spearfishing traditionAspetto and agguato are Italian because the modern discipline was codified there, and the words travelled with the techniques.

Widely and independently recommended by experienced anglers and specialist sources. This is real angling knowledge, not proof: controlled evidence for it is limited, and FishingHQ records it as convention rather than as a demonstrated effect.
