5.4 Waypoints
The MARKS key lets you to place up to 998 waypoints. A waypoint is a position,
normally entered on a chart as a reference, or as a place to go to. This section
provides details that are specific to placing Waypoints in Sonar mode.
Note: You can only place a waypoint in Sonar mode if you have valid position data from
a GPS.
A waypoint can be placed at the cursor position or at the boat’s current position
(this is sometimes known as an event mark); all waypoints placed on the sounder
are stored in a waypoint database list with position, depth and temperature when
it was placed.
Waypoints placed on the sounder are displayed as a solid vertical line on the
scrolling bottom, Zoom and Bottom Lock displays. The waypoint number is shown
at the top of the vertical line. The waypoint scrolls to the left with the scrolling
bottom display.
If you place a waypoint at the cursor position in Sonar mode and a chart window
is open, the waypoint is displayed on the chart. You can GOTO, EDIT and ERASE a
cursor waypoint.
