1.15 How to Use the Range/Bearing Marker
The range and bearing marker function is used to measure the range (distance) and
bearing from your ship to a specified location on the display, such a fish school or a
reef.
The range marker behaves differently depending on the display mode in use. See the
following display examples for details.
To show an range mark, press the RANGE key . The range mark moves with
the cursor. Move the cursor to the location to be measured.
Depending on the display mode in use, the range mark is displayed in a different man-
ner, and measurements also differ.
Horizontal display mode
The cursor location indicator shows the range (horizontal), depth and bearing to the
cursor location. The train indication also shows the range (horizontal) and range to the
cursor as a dashed line.
The range ring and bearing line move with the cursor.
