is the current zoom scale. This scale is changed using the 

RANGE 

keys. The zoom scale is represented by the Range Ring with tick 

marks around the circumference. The tick marks are arranged with 

major tick marks at thirty-degree increments and minor tick marks 

every fi ve degrees. The tick marks can help in quickly determining 

the azimuth to a target. The lower scale represents the distance 

between the Range Rings.

of your current heading.
