LOS Mode
The Ranger
®
1300 LOS (Line of Sight) mode is intended
for rifle shooters who are using slope correcting ballistic
drop data cards, ballistic cell phone applications, or other
devices with ballistic programs and who are shooting at
distances beyond 500 yards and with slopes greater than
15 degrees.
The range number displayed in LOS mode is the actual
line of sight range with no ballistic correction for slope.
Most of the commonly used ballistic devices can provide
independent slope correction for bullet drop data and
require actual line of sight range input. Using the LOS
range when calculating bullet wind drifts under these
steep slope/long range conditions will provide a higher
degree of accuracy than using the HCD range.
To use, simply input the LOS range number into the
electronic device or use the LOS range when referencing
ballistic drop cards with slope correction.

LOS Mode – Using the Incline Number
When in LOS mode, an additional number is displayed below
the yardage number. This number is slope shown in degrees.
The slope incline number can be used with drop charts
or field cards to calculate precise bullet drops in
mountainous terrain.
