Black-Out Plus Threaded Shaft

Black-Out Plus Threaded: Shaft for Spearfishing and Freediving

The Black-Out Plus Threaded shaft is a proven choice for spearfishers targeting large prey, particularly suitable for use in ocean environments and Mediterranean waters.

Technical Features

• Made from ground, certified 17.4 PH stainless steel bars, ensuring straightness, strength, and a smooth surface finish.
• CNC production for dimensional precision and consistent build quality.
• Available in 8 specific diameters: 7.0, 7.5, 8.0, 8.5, 8.75, 9.0, 9.5, and 10.0 mm, to suit different spearfisher needs.
• Length range from 125 cm to 170 cm, allowing selection based on rig setup and target species.
• Threaded Tip supplied as standard with M7 connection, with 5/16 or M6 alternatives available on request.
• Configuration with 4 shark fins, including 3 rear fins and 1 preload fin, positioned at 60, 90, 120, and 360 mm from the base of the Shaft, inspired by shark-fin morphology to maximize stability and Shaft travel during the shot.
• Finely angled shark fins, 4.5 mm high, welded with a continuous bead, ensure a strong attachment and allow the use of different types of wishbones, including Dyneema line.

Applications and Benefits

The Black-Out Plus Threaded shaft is designed for spearfishing and freediving focused on large fish. The combination of selected materials and precision machining ensures excellent mechanical strength and durability even in demanding marine conditions.

Thanks to the support fin design, the shaft ensures efficient power transfer and smooth tracking, helping deliver accurate, powerful shots. The variety of diameters and lengths makes it possible to optimize the setup while diving, improving comfort and control.
