Sectus Inverno i.p. Speargun

Invert Polyspast Version of Sectus Inverno – Our Best-Selling Model
The invert polyspast version of sectus inverno , our basic and best-selling model, with several innovations has won the trust of many experienced and non-experienced anglers for many years with its excellent performance. The body of the speargun is crafted from Burma Teak with 5 to 8 layers (depending on the size), providing significant mass and volume, making it ideal for heavy setups with minimal recoil.

Optimal Design for Rigidity and Smooth Movement
Its configuration ensures absolute rigidity , and very good movements.
With the volume “pulled” to the back of the fish rifle near the handle, keeping the volume at reasonable levels as you move towards the head, we have achieved the best possible balance in mass, and horizontal/vertical movements.

Perfect for Ambush and Open Water Hunting
Ideal for ambush and open water fishing for big game.
The trigger mechanism is Meandros or Ermes Sub while the set-up is configured as in the chart below.

Customizable Buoyancy with Balance Slots
At the bottom of the body, there are two balance slots, allowing the user to easily add or remove ballast to fine-tune the speargun’s buoyancy according to personal preferences.

Ergonomic Handle for Optimal Comfort and Grip
The handle, available in ambidextrous or anatomical form, with anti-slip design and ideal angle, ensures a firm grip and optimum performance during use.

Rubber Band Loading System for Maximum Efficiency and Maneuverability
The main rubber band is anchored behind the reel, ensuring the longest possible loading length, while the other 2 pairs are loaded on the right and left side of the gun.
With this arrangement, the power bands are mostly hidden by the body of the rifle thus affecting horizontal movements to a minimum. With the use of a 3 position pulley, the power bands come completely parallel to each other and lay on the body of the rifle without tangling.
An extra pair can be mounted in the special positions on the head of the rifle as a booster.

Innovative Shaft Rail for Faster Shots
The shaft rail, our tried-and-true formula, consists of five or six points (depends on the speargun’s size) symmetrically distributed along the length of the rail and covered with carbon fiber, while the remaining rail is at a lower level. This design allows the shaft to launch at a greater speed, as it essentially only touches these six points, significantly reducing friction compared to conventional rails.

Individually Tested for Peak Performance
All of our spearguns are individually tested and balanced before delivery to ensure optimal performance.

Special Edition with Carbon Fiber Reinforcements
The Special Edition version differs with the addition of carbon fiber reinforcements in the following areas:

• Upper rear section
• Trigger guard
• Reel base
• Covers of balance slots
