Abstract: A sight apparatus for an archery bow which compensates for both the distance to a target and the elevation of the target. The sight apparatus includes a range finder mechanism and a pendulous sight. The range mechanism and the pendulous sight are operatively connected such that the setting for the range to a target positions the pendulous axis. The pendulous sight has a sight element which is suspended from the corresponding pendulous axis to provide a point of aim at the target. The range mechanism includes an adjustment arm which is pivotable to a known or estimated distance. The range mechanism also includes a pair of bracketing pins wherein one of the bracketing pins is movable relative to the other bracketing pin along an arc shaped travel path for bracketing the target and providing a range setting determined from the size of the target.

Abstract: A repeating spear gun for firing self-propelled spears, the spear gun having a magazine comprising a plurality of spear firing chambers disposed as radial sets of firing chambers, and a bolt having a plurality of firing pins, each firing pin aligned with a firing chamber in the firing path of the bolt. The firing pins are staggered to provide varying firing pin distances to the respective firing chambers positioned in the firing path of the bolt. The firing pins are thereby caused to arrive at the respective firing chambers at different times, and if a spear occupies the firing chamber nearest the bolt, the spear is launched and the exhaust gas therefrom brakes the bolt to prevent firing of a spear contained in another firing chamber. If the firing chamber nearest the bolt is unoccupied, another firing pin will ignitingly impact a spear disposed in another firing chamber of the radial set.
