If a geodetic mark's ["datasheet"] has the word SCALED to the right of the mark's coordinates, those coordinates are based on scaling (with a ruler) using a topographic map. Such coordinates are given to the nearest second with zero decimal places. Scaled coordinates can be off by as much as a few hundred feet.  Therefore, hunting such a benchmark absolutely requires using the [:to reach:to-reach] part of the datasheet. If a geodetic mark's ["datasheet"] has the word SCALED to the right of the mark's coordinates, those coordinates are based on scaling (with a ruler) using a topographic map. (If not SCALED, it will say [:adjusted:ADJUSTED].) Scaled coordinates are given to the nearest second with zero decimal places. Scaled coordinates can occasionally be off by as much as 6 seconds, which translates to roughly 600 feet. Therefore, hunting a scaled benchmark absolutely requires using the [:to reach:to-reach] part of the datasheet.
