using the reticle
Cavalry models 71420, 71422 and 71215
have an integrated reticle that can be used to
estimate size and distance. The reticle is divided
into 10mil increments with 5mil marks between
each 10mil increment. Each 10mil increment
is indicated using single digit numbers (1, 2,
3, etc.). For finer ranging ability the last 5mils
of the reticle are divided into 1mil and 0.5mil
increments.
calculating distance
Using the simple formulas below, you can
effectively determine the distance to the
target if its size is known.

Note: The reticle varies slightly from model to model but this does not
affect how distance and size are calculated.
