Ghost Shaft

Sigal Sub Ghost Tahitian Shaft for Spearfishing

The Ghost shaft by Sigal Sub is an innovation in the production of shafts for band-powered spearguns, designed to deliver maximum hydrodynamics and accuracy in spearfishing. Made from high-quality Swedish Sandvik steel, heat-treated to ensure optimal strength and rigidity, this shaft is ideal for those seeking a clean trajectory with no wobble during the strike.

Technical Features

• Material: Sandvik steel, known for its mechanical strength and durability in marine environments
• Available diameters: 6.5 mm and 7.0 mm
• Lengths: from 110 cm up to 160 cm, to fit different types of band-powered spearguns with open or closed muzzles
• Low-profile pins: protrude less than 1 millimeter from the shaft profile, improving hydrodynamics and allowing secure engagement of metal or Dyneema wishbones thanks to the machining in front of them
• Hand-finished tail: removes sharp edges and cutting points, increasing user comfort and safety

Innovation and Design

The distinguishing feature of the Ghost shaft is its patented retractable flopper, made from 2.0 mm untreated AISI 316 stainless steel. This flopper is housed in a longitudinal milled recess in the body of the shaft:

• When the shaft is at rest, the flopper remains completely recessed into the profile, further improving hydrodynamics
• As it passes through the prey, a spring-loaded metal tab in the groove allows the flopper to open for effective fish retention

This exclusive system helps make the Ghost one of the smoothest shafts in the water, optimizing the speed and accuracy needed especially when hunting white fish.

Benefits in the Water

• High rigidity and elastic rebound maintain a stable, direct trajectory
• Extremely hydrodynamic design for reduced drag as it travels through the water
• Compatible with different band-powered speargun setups, thanks to the available diameters and lengths
• Practical wishbone engagement, both metal and Dyneema, thanks to the optimized low-profile pins
