Great Hawk Wind Indicator

The precision balanced Reference Arms, made of glass-filled nylon for rigidity, can be preset at any angle (eg 55, 60, or 65 degrees) & can be used for either upwind or downwind angles. While the 5mm Aluminium support rod is strong enough for normal wear & tear, it can be bent straight should it be knocked while the mast is being stepped or unstepped. The Great Hawk is easily removed from its mounting bracket with one screw; the mast bracket can be mounted vertically or horizontally. It can be bolted down to any pre-drilled mast head crane 8mm holes (adapator with nut & bolt supplied)
