USING THE RETICLE

CALCULATING DISTANCE

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.

Note: The reticle varies slightly from model to model but this does not

affect how distance and size are calculated.

Using the simple formulas below, you can

effectively determine the distance to the

target if its size is known.

Target Size (Yards) x 1000

Measured Mils

= Range (Yards)
