Abstract: A system for establishing a base between a light projecting station and a light receiving station of a triangulating coordinate finder incorporates a target on the light transmitting station and a reflector appropriately positioned relative to a photo sensitive receiving array in the light receiving station. A beam of light is directed through a peep hole through the target onto the reflector and is reflected back onto the target. By adjusting the relative orientation of the two stations so that the light beam is reflected back from the reflecting surface in a direction substantially co-axial with the beam of light projecting through the peep hole the bases of the two stations are arranged to be substantially in the same plane and on a base line. The base length between the two stations is measured and the orientation of the projected beam and the focal axis of the receiving station are established relative to the base line to provide coordinates for the triangulating coordinate finder.

Abstract: A novel apparatus for semi-automatically baiting the hooks of long-line used in commercial deep sea fishing. The apparatus includes a bait holding receptacle, a slotted separator positioned in or in association with the receptacle and extending from substantially end to end thereof, whereby ground-line with leader periodically attached to the ground-line is passed behind the separator such that a gangion portion of the leader extends through the slot in the separator and the hook of the leader secures itself to a piece of bait held in the bait holding receptacle.
