Note:An alternativemethodof measuringrange andbearing isto usethe cur-
sor data box: If the cursor readout is set to display range and bearing (rather
than Lat/Long), you can determine the range and bearing by moving the cur-
sor over the target and checking the cursor data box readings. You can also
estimate the range to a target by reference to the range rings.
Measuring Range and Bearing to Target from Vessel
To measure the range and/or bearingof a target or point from your vessel’s
position,you need to place a VRM/EBL and move it so that it crosses the
target or point for which you require the bearing or range.
When you turn on a VRM/EBL, it is displayedin its last-usedposition.
Note: If the VRM’s last-used position is outside the radar picture at the cur-
rent range setting, it is placed at its default position instead. This is one third
of the range for VRM1, and two-thirds for VRM2.

Placing and positioningVRM/EBLs on the PathfinderPlus Radar display is
quickand easy.
• If a VRM/EBL is not already displayed, you can place one with a single
