Measuring the Bearing

There are three ways to measure the bearing to a target: by the bearing scale
(rough estimate), by the cursor, and by the EBL (Electronic Bearing Line).
1.18.1

Measuring bearing by the cursor

Rotate the trackball to set the cursor intersection on the center of the target. The
bearing to the cursor intersection appears at the bottom of the display.
1.18.2

Measuring bearing by the EBL

Use the EBLs for accurate measurement of the range to a target. There are two
EBLs, EBL1 and EBL2, which appear as dashed rings to as to distinguish them
from the range rings. The two EBLs can be distinguished from each other by
different lengths of dashes.
1. Press the [EBL1] or [EBL2] key, whichever EBL you want to use. The readout
of the active marker is circumscribed.
2. Operate the trackball within five seconds of completing step 1 to bisect the
target with the EBL.
3. Check the EBL readout to find the bearing to the target.
