Sorry, but you have been supplied incorrect information in my absence (I was on vacation).

All marine and military binoculars use an optical grid rangefinder, NOT a laser rangefinder. An optical grid rangefinder uses a reticle which requires you to know the height of the object in question, then do mathematical calculations. This is an old technology that survives in marine binoculars more out of tradtion than usefullness. To be honest, it is impractical for field work.

You calculate range according to the following equation. It does not matter what units you use (feet, yards, meters, kilometers) as long as you use the same unit for all variables.

Distance to the target equals actual height (must be known in advance) of the target divided by the reticle height (number of lines the tagret occuoies on the grid).
