Aprašymas

Propulsion system

The propulsion system is made up of two pairs of straight Sigalsub Extreme 16 mm elastic bands that attach to the lower part of the handle that Sigalsub had designed on the Nemesis precisely considering the possible evolutions in the Roller and “Inverter” versions ”. A third pair of 16 mm Sigalsub Extreme elastics is connected laterally to the barrel, just in front of the handle thanks to two small “mushrooms”. The latter are extremely refined, with the radiused base that fits perfectly with the profile of the Nemesis stem. The three pairs of elastics are then connected to two pulleys, one on each side, which in turn are connected to two lines which reach the rollers on the muzzle and then close like a fork.

Muzzle

The muzzle is one of the extraordinary works of art of the Sigalsub Nemesis HT. Its design allows for an extremely low weight and a compact shape. It is made of Glass loaded Nylon, but the percentage is not too high to maintain the smoothness of the surface of the material and thus allow good sliding of the elastics and lines.

The structure

The construction of the muzzle is fantastic. It has a rigid and resistant part on the upper surface and near the holes where the line passes. This gives the head an extraordinary resistance. At the same time, the central 8 mm diameter steel axis on which the two rollers rotate gives great transversal rigidity. The remaining parts of the glass-filled nylon muzzle are thin enough to reduce weight and elastic enough to bend but not break.

Rollers

Sigalsub worked hard to choose the best rollers that could give great performance with excellent weight reduction. The rollers are made of polyoxymethylene (POM). POM, also known as acetal, polyacetal and polyformaldehyde, is an engineering thermoplastic material used in precision parts requiring high rigidity, low friction and excellent dimensional stability . The central axis positioned between the steel axis and the roller is also made of POM. This element is expertly designed with 5 tenths of a mm more than the roller, so that the latter is always free to rotate without friction on the side walls of the head.

Pulleys

The pulleys are made in Sigalsub, which means Made in Italy. They are designed specifically for the needs of this fantastic new speargun. The pulleys are made up of two steel plates connected to two axles of the same material. On one of the two axes, on the handle side, the three pairs of elastic bands are connected. A POM roller is mounted on the other, over which the line passes up to the muzzle. The steel axles can be dismantled with an Allen screw. The positioning of the pulleys is carried out correctly by passing the slots of the elastic lines in a precise way such that the pulleys are parallel to the shaft and do not rub on it, thus avoiding scratching it.

Loading

Loading an “Inverter” type speargun is obviously more complicated than traditional single or double band ones, but obviously the power released is extremely greater. The loading action begins with the two pairs of rubber bands detached from the bottom of the handle. Without the need for a load, the spearo can easily grab the loop connected to the spinner and pull it all the way along the rod, hooking the wishbone to the fin of his choice. Subsequently you can turn the Sigalsub Nemesis HT upside down and attach a first pair of elastic bands. In the final version of the Nemesis HT the first pair to be hooked is the one with the black line. The last pair of elastics has a white line to hook under the handle (just above the reel).
