Figure A shows the default screen layout. With the speed and temperature gauge connected a distance back number is displayed which represents the linear distance of the sonar information being displayed. The faster your boat is traveling, the greater the distance number. If you are not using the temperature/speed accessory, the screen layout will be slightly different, as shown in Figure B.
If you are using the Wide Side accessory transducer, the screen layout will look like Figure C.
Later, you will learn of another feature called "advanced operation". This feature uses yet another screen layout as shown in Figure D which maximizes the display for the terrain and target presentation.
The number of vertical pixels (picture elements or dots) in a given depth range determines the display resolution, or ability to differentiate targets close to the bottom or other targets. The Wide Vision is capable of distinguishing between targets only 6 inches apart, and show fish within 6 inches of the bottom.
On all screens but the Wide Side view, the horizontal line at the top of the display is the "Zero" line. This represents the surface of the water. The "Zero" line will always have a gap which moves as the screen updates. This gap lets you know that the display is updating even if the bottom terrain remains the same or is not visible on the selected depth range. The farthest right column of information is the most recent information, and it shows what is directly under your boat.
