For example, when you are in the split screen Chart/Track
Plotter display, the Track Plot will appear on the right side of
the display and the softkey menu will allow you to change the
Track Plotter settings. In order to make changes to the
downlooking Chart display, you must go to a display where the
Chart display is on the right side of the display (such as the
Chart mode).
In addition to the fact that the softkey menu typically relates to
only the right side of the split screen displays, other features
such as Bottom Hardness and Fish Symbols will not appear in
Zoomed, Bottom Track or Bottom Locked displays.
Cone Angle & Area Covered to Side
The Sea Scout’s 1/2 Power Point Cone Angle is approximately
12 degrees. The Chart at right shows the approximate width of
the cone at different distances from the boat. Although 50% of
the acoustic radiation is concentrated within this cone, 50% is
also outside the cone which permits the Sea Scout to detect
targets typically up to twice the 1/2 power cone angle, (i.e. 24
degrees). This means, for example, that at 1000 feet the Sea
Scout will typically be able to see targets across a 420 foot
width (210 feet each side of center). See Figure at below.
