Uragano 115 - Cetma Composites

The Uragano 115 is the flagship full carbon speargun by CETMA COMPOSITES: a spearfishing gun with a clean, elegant shape, fully profiled with a cuttlefish-bone geometry, engineered to deliver maximum performance on every dive. Supplied ready to fish, with all standard accessories already installed, it is the choice of the most demanding spearfishermen.

Design and Geometry

The barrel profile follows the distinctive cuttlefish-bone shape, extremely slim and tapered toward the muzzle, for optimal lateral tracking and smooth underwater maneuverability. The study of its geometries and volumes is not purely aesthetic: every detail is calculated for load balancing, maximized flexural stiffness, and reduced recoil. Along the entire lower section, the power unit — made up of the bands — is properly spaced from the barrel to eliminate any friction or vibration during the shot and make loading easier.

Dimensions

• Average thickness: 2.5 cm
• Muzzle width: 5.5 cm
• Maximum width: 10 cm

Construction: High-Modulus Carbon Monocoque

The barrel is a closed-structure high-modulus carbon monocoque, manufactured using CETMA COMPOSITES’ proprietary Zero-Defects Technology process. This completely innovative process makes it possible to produce a fully monolithic carbon fiber component with zero voids, maximizing structural performance and giving it the highest possible rigidity, unalterable over time.

The internal structure is made from a very low-density multifunctional polymer material with Aerospace-derived structural properties: a closed-cell polymer core with excellent vibration damping capability.

Finish

Anti-reflective matte, unpainted finish. CETMA COMPOSITES products are not painted: this is a sign of absolute quality, since low-quality carbon products often use paint to hide production defects.

VELA System: Performance Beyond All Expectations

The Uragano 115 is equipped with the proven VELA System, developed exclusively by CETMA COMPOSITES. Thanks to an innovative stopper positioned after the pulleys, the system provides a completely clear line of fire, allowing centimeter-accurate shots well beyond 7 meters with zero recoil. The pulleys are made of high-strength Derlin.

Standard Equipment (Ready to Fish)

Arrow Carbon Speargun - Cetma Composites

The Arrow speargun by Cetma Composites is a monocoque carbon band speargun with extreme lines, designed for inshore spearfishing. The shape of the barrel recalls an arrow: a radically minimal design, with no muzzle, providing a perfect sight line with full view of the shaft in all conditions.

Monocoque Design and Maneuverability

The monocoque carbon structure is shaped with side grooves that bring the bands closer to the shaft, minimizing the speargun’s cross-section. Thanks to the recessed band geometry and the ultra-thin profile, the Arrow is extremely maneuverable and easy to swing, both horizontally and vertically — essential for moving nimbly among rocks and inshore crevices.

Reel Integrated into the Barrel

The reel is integrated directly into the barrel, available in two line-capacity versions: 50 meters or 90 meters. This construction solution eliminates external protrusions, making the speargun even sleeker and better balanced without sacrificing line capacity. A design choice that translates into real maneuverability while hunting.

AISI 316L Stainless Steel Release Mechanism

The release mechanism is made entirely from AISI 316L stainless steel by EDM machining, ensuring maximum dimensional precision, resistance to marine corrosion, and long-term reliability. The system used is the double-roll mechanism with integrated line release, with the option to position the line release on the right or left side according to the spearfisher’s preference.

Bands and Shaft Setup

• Bands: Black Progressive CETMA Composites Bands
• Double-band configuration: two pairs with 14 mm diameter
• Single-band configuration: 17.5 mm diameter
• Shaft: 6.5 mm diameter × 115 cm length
• Shaft with single flopper and double loading tabs
• Recommended band: Progressive Black

Availability and Lengths

The Arrow carbon speargun is available in multiple lengths to suit different hunting needs and seabed profiles. The Standard version offers an optimal balance of power, accuracy, and maneuverability for inshore spearfishing and rocky environments.

Cetma Composites Technology

Cetma Composites designs and manufactures its spearguns using a proprietary production process called Zero-Defects Technology, which makes it possible to obtain fully monolithic carbon fiber structures with zero internal voids. The result is maximum stiffness, unchanged over time, and superior build quality — to the point that Cetma products are not painted, leaving the carbon exposed as a guarantee of manufacturing excellence.
