5.6 Determining depths and distances of targets
The fishfinder provides various features to determine depths and distances:
• Depth reading - your current depth displayed. The size and position of this digit
can be changed via the Fishfinder display Setup menu (see page 110 ).
• Depth lines - horizontal dashed lines drawn at regular intervals to indicate the
depth from the surface. These are switched on/off via the Fishfinder Display Setup
menu (see
page 113 ).
• Depth Target ID - depths noted against recognized targets. The sensitivity of
these IDs is directly linked to the Fish Alarm sensitivity; the greater the fish alarm
sensitivity, the greater the number of labelled returns. These targets are switched
on/off via the Fishfinder Display Setup menu (see
page 113 ).
• Cursor depth - the depth and the distance from your boat marked by the cursor,
is indicated in the data bar at the top of the screen. This performs in a similar way to
a VRM, but without lines.
• VRMs - to indicate the distance behind your boat and the depth below of selected
objects. For further information see page 109 .
