Bow Ballistic Group - Leupold RX Operating Instructions Manual

FUNCTION 14: BOW BALLISTIC GROUP
This mode, when activated, works with TBR to provide
the correct ballistic range for arrows. To select, be
sure that TBR is turned off (follow instructions In
Function 13), then select BOW by pressing Set or Power
on RX-II. The range that displays will correspond to the
target. It incorporates three different groups (Group A, B, or C) depending on
the particular arrow drop. You must choose one of the three groups, based
on your bow and arrow selection. Only one group can be selected at a time.
Selecting a new group deactivates all other groups. Most importantly, using
TBR effectively means Practice, Practice, Practice. Anytime you handle a firearm
or bow, you are ultimately responsible for where your projectile ends up.
