Using the HCD Mode
Use the HCD range mode in the following situations:
• Rifle shooting on level ground at any range.
• Rifle shooting out to ranges of 800 yards with mild
slopes (less than 15 degrees).
• Rifle shooting out to ranges of 400 yards with moderate
slopes (15 to 30 degrees).
• For all archery shooting.
The displayed HCD yardage number is corrected for shot
angle and needs no extra user input; shooters simply use
the appropriate level ground bullet drop for the range
displayed and shoot. Archers use the appropriate level
ground sight pin for the range displayed and shoot.
LOS Mode
The 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 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.
