Folding staff

Folding staff usually 10ft long having a hinge at the middle of its length. When the staff is not in use the rod can be folded about the hinge so that it becomes convenient to carry it from one place to the other. Since the self-reading staff is always seen through the telescope all readings appear to be inverted. The readings are therefore taken from above downwards.
