NEW SHAFT SIGALSUB HRC WITH WELDED PINS 

AVAILABLE IN MAY

The new shaft by Sigal is called HRC and takes its name from the hardness test of the steel which is conducted by penetration with a diamond point. The shafts are made of sandvik steel with heat treatment 48 / 50HRC that makes them very tenacious even when they hit the hardest rocks. The peculiarity of this new series is represented by the presence of "shark-fin" pins that are laser-welded in a non-through housing which avoids the presence of structural critical points.

All the shafts are equipped with 4 fins, 3 of which are grouped together in a backward position while the last one is more distant and it is aimed to help loading the speargun only. The position of the latter can be customized according to the user's needs, as indeed many other features (barb position, barb number, diameter, tip type, etc.). All the fins have the hole for the passage of the monofilament in order to offer a wider range of possibilities to the user. All are polished and finished by hand so as not to have abrasive edges that could damage the monofilament.

The fins can have two sizes so you can choose between 5mm height and 3mm height according to your desire. Another important feature is the presence of a larger barb and a totally revised tip design.
