The Tahitian shaft TANA version has a tip length reduced to 4cm, without milling for the barbs, to increase resistance to impacts on the rocks. Furthermore, the fin is short and equal to 6 cm. The connection with the nose cone is made through pins.

The design of this shaft makes it ideal for fishing in holes or for lurking among boulders, thanks to the small size of the tip and fin, which facilitates shooting prey near rocks.
