This simple rod unfolds into a number of different configurations. It can be extended from 6 inches to 30 feet, closed, and then reopened to the same length. Placed on a surface (horizontal, vertical, or other), it will indicate degree of slope or pitch, and can indicate and lock at any angle. Markings on the rod assist the user in mathematical equations, to determine volume, quantity, and etc. A portion of the rod detaches; this portion will indicate distance and change in elevation from the main section when commanded. The rod can be separated into a chain reaching 66 feet; this chain is fragile and cannot support more than 10 pounds of weight. A carpenter’s rod does not use charges.
Wow! We could use such a "single" instrument here in the Real World! LOL
