Features:
* Fin System: FCS II
* Fin Set Up: Thruster
* Colour: Smoke
* Construction: PC Carbon
* Suggested Conditions: A wide range of conditions, particularly good in critical overhead waves
* Recommended Board Type: Recommended for performance shortboards with moderate-to-low rocker
* Accelerator fin family - Find Control. Speed, flow and response with added control
* Radically different side & centre fin templates create a powerful fin set with ultimate speed & drive
* Side Fin Profile: Lower section produces maximum acceleration, while hatchet like tip creates stability & control
* Centre Fin Profile: Highly raked elliptical outline reduces drag, and offers feeling of predictability when releasing through turns
* Fin Foils Template: Thicker base with tapered tip optimises flex & regulates the release of energy during rail to rial transitions
* Precision Swiss engineering creates perfect synergy between fin geometry & HI-FI materials, giving smooth & predictable feel
* High density uni-directional carbon fibre is light & super strong with custom orientation to transfer more of your energy into speed than any other fin
* Dynamic trailing edge internal composite morphs under extreme load, enabling the fins to be pushed harder without sliding out
* Innovative production uses highly specialised robotic automation combined with camera assisted quality control, ensures absolute accuracy

The H4 looks and surfs different to any other fin. Precision Swiss engineering matched with a highly evolved template provides an unprecedented level of control and predictability at high speeds.
