Range Estimation
The reticle in the SWFA SS 12x32 binocular provides both
horizontal and vertical hash marks for estimating range using
either horizontal or vertical dimensions of objects of known size.
The reticle is designed to remain unobtrusive during regular
observation while being immediately available when needed.
The maximum object size that can be measured with the reticle
is 45 MRAD. The spacing between hash marks is 1 MRAD and
the stadia are marked at 5 MRAD and 10 MRAD intervals with
longer hash marks and numbers next to them.
The longer hash marks at marked 5 MRAD locations are
1.5 MRAD long.
The hash marks at marked 10 MRAD locations are 2 MRAD long.
The length of the short hash marks is 1 MRAD and they are 1
MRAD apart from each other.
