This version includes improvements made for the rubber tubes. With the sheaves, the tubes are easy to replace and their lifespan is increased. When throwing, the two sheaves spin on themselves and the power is transferred to the throwbag.
The ergonomic form of the pouch holds and centres both small and large throwbags.
The SLING-LINE head can be placed on Silky (Hayauchi, version with 3 elements), Berger (with adapter) and ARS poles. A complete version of the SLING-LINE is available, with a prepared Hayauchi pole.
