Measuring Rod Rulers are some very handy tools to have if you're measuring the height from the ground to the underside of overhead utility lines, underneath bridges, or underneath overhangs.
Measuring Rods are dual-purpose tools since they have special measuring ruler scales on their backside which will permit users to read heights. To use a measuring ruler, just extend the rod up until it hits the desired length (underneath an overhang or bridge for example), then read the measurement at the smallest unextended section which is at eye-level. This will give you the distance from tip-to-tip of the rod. Great tools to have in certain situations.
