Sectus Inverno Speargun

Inverno – The Best Seller Handcrafted Speargun for Superior Performance
The Inverno model, our core and best-selling open muzzle model, has earned the trust of many experienced and novice spearfishers due to its exceptional performance and numerous innovations over the years. 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 design ensures absolute rigidity and smooth movement in the water. By concentrating the mass toward the rear of the speargun, near the handle, and maintaining a more moderate volume as it tapers toward the head, we have achieved the perfect balance of mass, allowing for effortless horizontal and vertical movements.

Perfect for Ambush and Open Water Hunting
Inverno is perfect for ambush and open water hunting, especially for large prey.
The trigger mechanism is Meandros or Ermes, and the setup is displayed to the size chart.

Muzzle Design for Better Maneuverability
The bands, thanks to the design of the muzzle, run almost parallel to the shaft, while the top design conceals most of the bands, allowing for better maneuverability and eliminating noise caused by the movement of the bands.

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.

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.

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.

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