Mounting rail made from AISI 304 stainless steel using a laser-cutting process, specifically designed for securely attaching a camera to Sigalsub Nemesis spearfishing spearguns.

The rail design ensures stable installation on the speargun handle, and includes two stainless steel screws for precise anchoring with resistance to marine corrosion.

Available in right- and left-side versions, allowing an ergonomic setup according to your preferred tracking style.

The rail is compatible exclusively with dedicated Sigalsub brackets, ensuring an optimal connection between the camera and the spearfishing speargun for smooth, stable footage during freedives.

• Double 14.5 mm Reactive rubber band, handmade and hand-tied to maximize responsiveness and efficiency.
• Reel positioned farther back to ensure smoother tracking and faster target alignment.

Variants and Construction Details

• Available in seven different lengths: 76 cm, 82 cm, 92 cm, 104 cm, 116 cm, 126 cm and 136 cm, to suit different spearfishing needs.
• Color: matte black to reduce visibility in the water.

Specific Benefits for Freediving and Spearfishing

The combination of durable materials such as Anticorodal aluminum and stainless steel, together with ergonomic and functional solutions such as the adjustable trigger and non-slip butt pad, ensures a balanced and reliable speargun. The option to mount Roller Speargun systems increases versatility, allowing the propulsion system to be adapted quickly according to the freediver’s preferences and fishing conditions.

Nemesis PRO Green Sigal Sub Speargun

Nemesis PRO Green is a three-piece, take-down band-powered speargun designed for spearfishing and freediving. Its modular construction makes transport and maintenance easier while maintaining high efficiency in the water.

Technical features and materials

The barrel is made from Anticorodal aluminum alloy with a variable diameter from 28 to 26 mm, offering an ideal combination of lightness and mechanical strength. The integrated shaft guide ensures responsive, smooth power transfer during the shot, promoting accuracy and control when tracking the target.

The trigger mechanism, together with the line release, is made from stainless steel, ensuring high durability and reliability in the marine environment. The open muzzle allows both single- and double-band configurations, while the adjustable trigger with extra-soft release improves operating comfort and release accuracy.

Ergonomics and versatility

The handle is designed for Roller Speargun systems, with compatibility at the reel mount and the handle-to-barrel joint. This allows a quick switch from a traditional circular-band setup to a Roller Speargun system by changing only the muzzle, with no further modifications required.

The ergonomic grip features an anti-slip orange thermorubber loading butt, designed to improve grip and comfort during freediving sessions.
