The digital depth shown on-screen is the depth of the water directly beneath your boat. As new
information is received, the most recent information is displayed at the lower right, directly
underneath the boat symbol. Previous information advances to the left. Boat speed and water
surface temperature are displayed at the upper right. If you have not connected this accessory,
the screen layout will be slightly different. The distance back number represents the linear
distance of the sonar information being displayed. The faster your boat is moving, the greater the
amount of distance will be seen on the screen.
As the depth of the water changes, the Wide 3D Vision will automatically adjust the depth range
and sensitivity as necessary to view the bottom on-screen. The 3D view of the Wide 3D Vision is
capable of tracking the bottom to a depth of 240 feet. Beyond 240 feet, you must select the 2D
view for bottom tracking to 1000 feet. When operating at depths near 240 feet in the 3D or
Combo views, A message will appear warning you of the depth limitations of the 3D view. Also,
the 2D view has a depth capability much greater than the 3D view. The 200 kHz transducer will
provide reliable target and bottom tracking to a depth of 1000 feet.
If a target is detected between the surface and the
bottom and it meets the fish identification criteria, it is
displayed as a fish symbol. Sonar returns that do not
meet this criteria are displayed as “raw” information.
Depending on the strength of the signal reflected from
the target, and other factors, one of three different size
fish symbols 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 indicator of fish size, however,
typically, the larger the fish, the larger the signal return.
Additionally, since the Wide3D Vision uses a six element transducer, the position of the target
relative to the boat is known. To help differentiate targets seen directly under the boat from those
seen in the outer beams, these fish symbols are indicated differently. Targets seen in the two
center beams are located directly under your boat, and are displayed as solid fish symbols.
Targets seen in the outer four beams are located in the outer portion of the sonar coverage area
and are displayed as hollow fish symbols. This is true for all views.
