The Ranger 1500’s LOS (Line of Sight) mode is intended for 
rifle shooters who are using slope correcting ballistic drop 
data cards, ballistic cell phone applications, or PDAs with 
ballistic programs and who are shooting at distances beyond 
500 yards and with slopes greater than 15 degrees. Most 
shooters and archers will not need the LOS mode.

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 INC 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.
