Humminbird Wide 3D manual

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 View will automatically adjust the depth range and sensitivity as necessary to view the bottom on-screen. The 3D view of the Wide 3D View 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 View 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.
