Speed Vector
shows you the predicted course and speed of the tracked target. The
Speed Vector
prediction is based on target's current movements. The estimate is limited to one
minute.
The information is provided with a line indicating the target's course. The length of
the line reflects its speed.
•
Bow Marker
This function displays a dotted line drawn from the bow of the vessel symbol. The
line reflects your vessel's current heading.
Do not confuse this line with the bearing line.
•
Current Vector
This function shows you the speed and direction of the water current under your
vessel. The function draws a line starting under the vessel symbol. The direction of
the line indicates the direction of the water current. The length of the line reflects
its speed.
For this function to work, a sea current meter must be connected to the SN90. The use
of an ADCP (Acoustic Doppler Current Profiler) is recommended.
