Before lasers
What are the older methods of scaling range. Before the use of lasers how did people measure yardage through binoculars/range finders. Were older binoculars or range finders built in guages? I can't help but imagine the parascope in a sub with its tick marks. I'm interested in the GPSvsCompass aspect here. I'm sure there are antique methods to scaling range with older equipment.
