Arrival alarm
Arrival alarm means that when the distance between
the boat and the target point is less than or equal to
the preset value, the device will make an alarm. At the
same time, a prompt message will be displayed on the
screen: "Approching the target position".
The default alarm radius is 5 meters. This means that
when the boat is less than or equal to 5 meters from
the target point, the fish finder will make an alarm.
In order to obtain a more precise positioning from
the target point, you can set it to a smaller value, for
example: 2 meters or even 1 meter.
Note: The smaller the value, the higher the navigation accuracy, and the boat will
be closer to the target point. But if currently the GPS satellite signal strength is not
enough and the value is too small (for example 1 meter), the boat cannot find the
target point. Therefore the red target point on the screen will always "drift" in the
compass display area.
