3-14 SL72 & SL72RC PLUS Pathfinder Radar & Radar/Chartplotter
Measuring Range and
Bearing to Target
from Vessel
• Measure the bearing of a target or point from your vessel’s position, using
an EBL
• Measure the range and bearing between any two points on the radar, using
the
FLOAT function
Note: An alternative method of measuring range and bearing is to use the 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 bearing of 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 displayed in its last-used position.
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 a VRM/EBL
Placing and positioning VRM/EBLs on the Pathfinder Plus Radar display is
quick and easy.
• If a VRM/EBL is not already displayed, you can place one with a single
press of the
VRM/EBL key.
• If you have already placed a VRM/EBL, pressing the
VRM/EBL key pro-
vides soft key control of additional functions.
➤ To place a VRM/EBL when one is not already displayed:
1. Press
VRM/EBL.
The radar picture shows VRM/EBL1, together with its associated data
box in its last-used position.
As shown in Figure 3-12, the cursor is positioned over the intersection of
the VRM circle and the EBL line. It has control of the VRM/EBL as indi-
cated by the four-way arrow, the solid VRM/EBL line, and the text VRM/
EBL.
