Single-piece speargun, with an interchangeable muzzle, made of nylon reinforced. The material used absorbs vibrations, thus making the gun silent, both when shooting and if it comes in contact with the surrounding environment. The cuttle-bone barrel and integrated shaft guide offer better accuracy. A specific design for every barrel length ensures perfect buoyancy, optimum stability, and easy aim. Sold standard with two different interchangeable muzzles for circular powerbands and supporting fork for double powerbands. The muzzles feature broad grooves to make it easier to place the line, and they can be personalized with special buoyancy regulators. No risk that water tightness will be compromised. The highly-sensitive stainless steel release mechanism is also suitable for use with strong double powerbands. The mechanical line-releaser can be used on the left or right. The handle and chest pad are both made of soft touch anti-slip material. The accessory reel, attached at an angle, increases hydrodynamics, preventing any risk of snagging along the bottom. Tempered stainless steel shaft, single-tip, 6.5-mm diameter. Advanced performance dual-component 19-mm powerband.
