Lead line depth measurement unit?

Explanation:
Depth measurement with a lead line is traditionally read in fathoms. A lead line is lowered into the water until it touches the bottom, and the depth is read from marks on the line; a fathom is the unit used for this purpose. One fathom equals six feet (about 1.8288 meters). Miles and nautical miles measure distance, not depth, and meters is a metric depth unit that isn’t the historical standard for a lead line. So fathoms is the best fit for this measurement method.
