My dad had an original linked chain when we had the farm. He used it occasionally. In later years I used a steel tape surveyor's chain to survey trails for the forest service.
Folks don't use the old units of measurement much anymore. Can't recall the that time I heard some one use rods, and one rarely hears the term furlong outside of horse racing. My granddad used to to refer to rods as a unit of measurement but I never heard it much from other than him.
Chronographs, bore scopes and pattern boards have broke a lot of hearts.
