摘要： One aspect is an illumination assembly including: a first light emitting element; a first counterweight; and at least one of a nock or a connector configured to attach the illumination assembly to a nock, such that the first light emitting element and the first counterweight are positioned symmetrically from each other relative to the nock on opposite sides of the nock. Preferably the first light emitting element is substantially the same mass as the first counterweight. The illumination assembly can include a shaft of an arrow or bolt and/or include an adapter configured to attach to a shaft of an arrow or bolt, such that the first light emitting element and the first counterweight are collinear on a virtual line substantially perpendicular to the central axis of the arrow or bolt, and such that the first light emitting element is positioned off of the central axis of the arrow or bolt and configured to emit light in a rearward direction offset from the central axis of the arrow or bolt.

摘要： A pin nock assembly comprises a pin and nock. The pin includes a pin base, a pin element positioned laterally away from the pin base, and a pin collar positioned between the pin base and pin element. The pin element protrudes laterally from the pin collar along a central axis. The central axis extends from a center of the pin base through a center of the pin element. The nock includes a nock base and a string interface positioned laterally away from the nock base. The nock base defines a pin cavity complementary to and configured to receive the pin element. A base portion of the nock base is positioned around the pin cavity and is configured to abut the pin collar when the pin element is inserted into the pin cavity. The string interface is configured to contact a string of a crossbow.
