A combination target reflector, light emitter and bracket assembly is disclosed for use in marking points during the taking of a land survey. The combination is pivotally connected to a central rod of a target tripod or a tripod that supports a target reflector. The disclosed combination includes first and second arms and a light emitter that is held in axial alignment with the target reflector. The first arm is pivotally and perpendicularly connected to the central rod of the tripod. The second arm is perpendicularly connected to the target reflector and the light emitter. The tripod can be moved close to a point to be marked, the tripod can be adjusted to plumb the target reflector and then the second arms, light emitter and target reflector can be moved out of axial alignment with the rod to mark the point without moving the tripod. As a result, the conventional trial and error procedure currently employed can be avoided.
