Later, you will learn of another feature called “advanced operation”. This feature uses yet another screen layout as shown in Figure C 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 W is capable of distinguishing between targets only 6 inches apart, and show fish within 6 inches of the bottom.
On all screens the horizontal line at the top of the display is the “Zero” line. 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.
