Thanks Dave. That is helpful. I was thinking the parallel bars could be used to estimate range, once I get them calibrated. I will take them to the range next time and see how much height they measure at 100 yds. The numbers on the vertical scale are confusing since they show a "5" at the top then a "20" at the bottom. I was trying to make degrees of angle out of it. Since I have little need to control fire my machine guns I will simply ignore the vertical scale.

Thanks again. BTW - these are surprisingly good binoculars although they have had heavy use.
