Meandros brings you a range of the most innovative ideas, improvements and solutions to tube speargun design in history!

The Meandros Argo Speargun Open is the flagship and most evolved speargun  from Meandros. It responds to the needs of the most demanding hunters that are not satisfied with simple tubular spearguns. This models features bright green right hand grip and gold or silver camo patterned black oval shaped higher volume and mass barrel.

The further increased strength and buoyancy of the Argo barrel allows the use of heavier shafts and the range of spearguns come in longer sizes, designed for larger fish.

Particular attention has been paid to all parameters that make up a superb quality product that is easy-to-use and offers unprecedented ballistic performance levels. It has been designed to overcome the problems and weaknesses of common aluminum or carbon tubular spearguns, such as intense recoil, deformations, buoyancy. The Argo offers long-lasting reliability and excellent operation of all its mechanical parts. 

The Argo is fitted with one of the most advanced ergonomic LEADER handle with a particularly low profile and a non-slip, right handed anatomic green grip. It has a loading butt and inverted full stainless steel heavy duty trigger mechanism with minimal weight and maximum sensitivity.

The reverse mechanism extends the loading length by 9.5 cm over conventional spearguns. It has an ambidextrous mechanical side line release, water balance to improve shaft speed, reduced friction guide and ambidextrous shooting line guide. Included bore hole allows easy adaptations to invert and roller style spearguns.

A milestone and benchmark is the revolutionary pin roller system. Meandros was the inventor of the the patented pin roller system. This offers reduced friction with zero wear at the point of contact with the bar but also distributes the load received from the bar at 3 points - two contact points at the housing and one point at the hook, which now accepts a small part of the pressure exerted and not 100% of it. The hook now has a much lower pressure at the point of contact with the trigger, with the result that the pressure exerted on the trigger to release the shaft is much less than a classic type reverse mechanism.

The included reel mount of the handle will fit any of the Meandros Reels, or other flat mount fixed reel. Handle comes with a sophisticated safety uniquely positioned in the base of the trigger guard.

The heavy-duty hydrodynamic oval shaped barrel is made of aluminum alloy with an integrated hydroplaning guide/ rail. This delivers stiffness with an ideal weight ratio and a fairly large, almost neutral positive buoyancy of 5.69 gr / cm. Neutral buoyancy in a heavy-duty cannon version is perceived by the user as a resilient, agile and powerful fishing tool. It has full anodising protection per piece, not per bar. The thickness of the barrel wall intentionally varies slightly, averaging 1.5 mm, through the circumference, for greater stiffness and strength.

Stiffness coupled with the absence of recoil, achieves shot precision and top ballistic performance at a distance from the tip of the spear to 5 times the length of the barrel. Much of the energy from the bands to the spear is absorbed and is lost in the recoil when the mass of the barrel and gun is generally disproportionate to the setting. The Argo is a sturdy and robust rig that guarantees rigidity with minimal energy loss from recoil. Similar performance with shot quality cannot be obtained from a common barrel of 28 x 1mm aluminum or carbon 30 x 2 mm. In order to maintain stiffness out-of-barrel too, attention has been given to the grip / head attachment points of the barrel in terms of geometry and static materials, so that at high load the deformation at the connection points is almost zero.

The open head type has a particularly elegant hydrodynamic design that makes the movement of the gun in any direction a simple easy task. The double bands are positioned in the muzzle in a different position and height, which contributes to agility, responsiveness, avoidance of vibration and friction between them.

The trapezoid-shaped spear guide contacts  the spear at 3 points, giving hydro-reduction with reduced friction. 

Speargun comes naked allowing you the freedom of choice of rubber and spear type and diameters depending on your specific hunting requirements.

Should you wish to have slightly less or more overhang, you can adjust the spear length accordingly.
