Aria Ghost Shaft

Sigal Sub Aria Ghost Tahitian Shaft in Sandvik Steel

The Aria Ghost shaft is manufactured by Sigal Sub using high-quality Swedish Sandvik steel, heat-treated to enhance its mechanical properties, such as stiffness and mechanical strength. This heat treatment gives the shaft the toughness and responsiveness needed to ensure a stable trajectory with no wobble during spearfishing.

Available in two diameters, 6.5 mm and 7.0 mm, and in multiple lengths from 95 to 137 cm, the Aria Ghost adapts to different pneumatic speargun setups and various handling and accuracy requirements.

Technical Features and Functionality

• The shaft is equipped with a standard tailpiece compatible with 11 mm barrel pneumatic spearguns such as the Mares Cyrano, ensuring broad compatibility; alternative tailpieces can also be purchased in the Pneumatic Speargun Accessories selection.
• The distinctive technology of this Ghost version is the recessed flopper, made from raw 2.0 mm AISI 316 stainless steel, set into a longitudinal milled channel in the shaft body to maximize hydrodynamics.
• When the shaft is at rest, the flopper is completely recessed into the shaft profile thanks to the O-ring in position, while a small spring-loaded metal tab inside the groove ensures the flopper opens for fish retention during the shot.

Benefits for Freedivers and Spearfishers

The combination of selected materials and innovative design gives the Aria Ghost shaft

• high hydrodynamics, with smooth penetration through the water, reducing drag and improving trajectory stability;
• stiffness and durability, essential for precise and reliable transfer of thrust during the shot;
• practicality and versatility, thanks to compatibility with different tailpieces and the wide range of available lengths;
• recessed flopper functionality, improving fish retention without compromising smooth movement through the water.
