2D Sonar View - traditional 2D sonar for the identification of structure and bottom hardness.
Boat/Direction Arrow - A simple, solid 3D boat is drawn when the Upper Depth Range is 0.
A solid 3D arrow is drawn when the Upper Depth Range is not 0.
Fish ID+™ - A fish icon will be shown at the derived position of the fish. Six fish icon styles
will be used to indicate the primary beam in which the fish was found. Left-facing fish
indicate fish off the port side of the boat, while right-facing fish indicate fish off the
starboard side. Each fish icon is available in three different sizes. Larger fish icons are used
to represent stronger returns. The icons used in the 2D Sonar View are identical to the icons
used in the 3D Sonar View.
