Sighting device for relocation of site

Abstract

A folding sighting device to define and then to relocate the point where the user is placed, said device allowing the user to simultaneously identify linearly opposite reference points to establish a first reference line, and to subsequently fix and record linearly opposite reference points to establish a second reference line which intersects the first reference line. The sighting device or site relocator has an elongated base member with coordinating sighting elements at the opposite ends so that an eye sighting can be made to identify a reference point at a distance from the user. The sighting device or site relocator likewise has a foldable and pivotable sighting member which is likewise elongated and having at least one planar surface towards the user. A mirror with an index line is mounted to the top of the sighting member so when unfolded a reference point is visualized in the mirror simultaneously as with the alignment of the reference point by the coordinated sighting elements on the base member. The two reference points establish the first reference line. The procedure is repeated to establish a second reference line and the intersection establishes the location point to which the user may later return by relocating the visualized reference points. Cooperating latch means are provided to hold the pivotable sighting member in folded, inoperative position against the base member. A grip is provided to hold the base member in sighting position so the reference points are sighted by the user in a common vertical plane, and adjustable stop means are further provided to fix the pivotable sighting member at a desired angle relative to the base member when it is unfolded to operative position.
