Spearfishing
Spearfishing is a discipline that requires specific equipment, designed to perform in a demanding environment where visibility, temperature, depth, and seabed characteristics determine every technical choice. There is no universal setup: every component of a Spearfishing kit meets precise needs that vary according to the technique used, the hunting environment, and the spearfisher’s level of experience.
Deep Blue brings together in this section the complete kit for Spearfishing, from rigging - spearguns, shafts, bands, wishbones, reels, lines - to technical neoprene apparel - wetsuits, socks, gloves. A range that covers the needs of beginners in shallow water as well as those practicing advanced bluewater hunting or hole hunting techniques at significant depths.
Product types
Spearguns
Spearguns are mainly divided into two categories: band-powered (railguns/arbaletes) and pneumatic. Arbaletes use latex bands to launch the shaft; they are quiet, intuitive, and easy to maintain. Pneumatic spearguns use compressed air, offer a power regulator, and may have a standard or vacuum muzzle (quieter and higher-performing, but with more complex maintenance). One variation of band-powered spearguns is the roller speargun, which uses pulleys to optimize band pull.
Shafts and bands
Shafts for arbalete and pneumatic spearguns are available in different diameters, materials, and configurations. The choice of diameter is related to the power of the speargun and the type of prey. Configurations include shafts with shark fins, notches, threaded ends, for prongs and slip tips, with single or double floppers (opposed or offset).
Bands for arbaletes are made of natural latex, available in various diameters, either with inserts or by the meter. Compounds range from reactive to progressive: today, intermediate compounds are preferred, combining power and accuracy.
Reels and lines
The reel is an essential accessory for medium-to-deep spearfishing and for hunting large pelagic fish. Mounted on the speargun, it allows you to manage the retrieval of fast, large prey without losing contact. Lines are available in nylon and technical materials (Dyneema) in different lengths and breaking strengths.
Neoprene wetsuits
Spearfishing wetsuits are generally two-piece suits, with a jacket featuring an integrated hood and high-waisted pants, made of open-cell neoprene, with a protective outer lining and inner neoprene in direct contact with the skin. This construction ensures maximum fit and minimizes water exchange. Available thicknesses range from 3 mm for warm waters up to 8 mm for winter months and cold water. Many models feature camouflage colors - camo patterns that reproduce rocky bottoms, seaweed, or Posidonia - with the aim of reducing visual contrast with the seabed and helping the approach to prey.
Fins
Spearfishing fins feature long blades that provide efficient propulsion with reduced energy consumption, a critical factor for maximizing breath-hold times. Blade materials range from technical plastic to fiberglass and carbon fiber. Carbon blades transmit kicking energy more directly and responsively than softer materials. Plastic or fiberglass blades offer greater flexibility and adapt to different finning styles. The choice of stiffness - soft, medium, or hard - depends on muscular strength, kick frequency, and operating depth.
Masks
Spearfishing masks are characterized by a reduced internal volume compared to conventional diving masks. Low volume requires less air to equalize at depth, reducing the use of lung reserves. Lenses are generally made of tempered glass. Many models feature dark lenses or anti-reflective treatments that improve visibility in strong surface glare.
Knives
Spearfishing knives are active safety tools, used to free yourself from lines and fishing line, dispatch fish, and fillet the catch. They differ by mounting position - belt, arm, or calf - and by blade type: straight, serrated, or double-edged. Blades are made of marine-grade stainless steel. They come with sheaths featuring belt or sock attachment systems and blades with two edges, one straight and one serrated.
Dive Floats, belts, and weights
The dive float is mandatory safety equipment: it signals the spearfisher’s presence at the surface to passing boats. Available floats vary in size, buoyancy, and the ability to accommodate a float board with line and reel. Belts and weight harnesses are used to distribute lead ballast along the body. Proper weight management is essential to reach neutral buoyancy at operating depths without excessive effort on descent and without risk on ascent.
Dive Lights, computers, and GPS
Underwater lights are essential for hole hunting, where artificial lighting makes it possible to locate prey inside seabed cavities. Spearfishing computers record depth, dive time, and surface interval, providing useful data for managing the session in the water. GPS units and fishfinders complete the setup for those who spearfish from a boat, allowing fishing spots to be georeferenced and the water column to be analyzed.
Practical use
Hole hunting involves actively searching for prey - groupers, moray eels, scorpionfish, lobsters - inside cavities in rocky bottoms. It requires short or medium spearguns (50-75 cm), underwater lights to illuminate holes, low-volume masks, and camo wetsuits that blend in with the seabed.
Ambush or aspetto hunting consists of waiting motionless on the bottom, or letting the body drop downward with minimal movement, until prey passes by. Sea bream, European seabass, dentex, and leerfish are the species typically targeted with this technique. The required equipment includes camo wetsuits, long fins to quickly reach depth, and medium or long spearguns with high penetration power.
Bluewater hunting - technically referred to as bluewater hunting - consists of hunting large pelagic fish in open water, far from the coast and the bottom, often at considerable depths. Target species include amberjack, tuna, mahi-mahi, and swordfish. This technique requires long spearguns with high-power roller systems, reels with long line capacity, large floats, wetsuits suited to ocean water temperatures, and a high level of physical and technical training.
Conclusion
Equipment for Spearfishing is the result of a balance between technically interdependent components. A speargun suited to the technique practiced, a wetsuit with the correct thickness for seasonal conditions, fins matched to the spearfisher’s physical characteristics, and precise weight management are the four elements that define the efficiency and safety of every Spearfishing session.
Deep Blue offers a selection of products and brands that covers the full range of needs - from beginners making their first experiences in coastal waters to expert bluewater hunting practitioners targeting large pelagic fish - with the option to explore each product category in detail through the dedicated subcategories.
