Using The Wide One Deep
What You See On-Screen
The first thing you may notice about the Wide One Deep unit is the high-resolution, super high-visibility
LCD screen. This LCD display uses super-twist technology, and is ruggedized for tough shock and
vibration endurance. The display is also backlit for nighttime operation, and uses special components so it
can operate at temperatures more extreme than you are likely to encounter.
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.
At power-up, the Wide One Deep locates the bottom and adjusts the depth range to a setting most
appropriate for that depth. The bottom will usually be shown about 2/3 of the way down the display.
The transmitted sonar signal travels downwards and is reflected back toward the surface by the bottom or
other objects for display on-screen. If a target is detected between the surface and the bottom, it is
displayed as a fish symbol. Depending on the strength of the signal reflected from the object, one of three
different size symbols is used. These reflected signals are “normalized” for depth, so that a small fish
does not appear to be a large fish if it is close to the boat.
Since some species of fish tend to be better reflectors of sonar than others, the strength of return is not
always an accurate indication of fish size, however, typically, the larger the fish, the larger the signal
return.
Control Functions
The Wide One Deep unit uses only seven buttons to control all functions. The controls are divided into
two groups: POWER, STOP, and LIGHT are one group, and the Menu System controls are the other
group. When any button is pressed, an audible “chirp” will verify the control input.
