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 indicator of fish size, however, typically, the larger the fish, the larger the signal return.
Additionally, since the Wide Eye uses a dual beam transducer, each of the two beams is evaluated independently, and some directional indication is possible. If a target is seen in the narrow beam, it is located directly under your boat, and is displayed as a solid fish symbol. If a target is seen in the wide beam only, it can be assumed that the target is at the outside of the sonar coverage area, not directly under the boat, and is displayed as a hollow fish symbol.
CONTROL FUNCTIONS
The Wide Eye 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.
