[. . . ] See Main Menu: User Mode for details. Sonar Menu 41 Sonar Menu Tab Fish ID+TM Fish ID+TM uses advanced signal processing to interpret sonar returns and will display a Fish Symbol when very selective requirements are met. When a fish is detected, a fish icon and its depth are displayed above the return that has been classified as being a fish. Three different fish size icons represent the intensity of the sonar return and provide an indicator of relative fish size. DualBeam sonar models represent targets detected in the 200 kHz narrow beam as Orange Fish Symbols and targets detected in the 83 kHz wide beam as Blue Fish Symbols. 200 kHz, Narrow Beam Orange Fish Symbols 83 kHz, Wide Beam Blue Fish Symbols When Fish ID+TM is turned off, the Fishfinder shows only the raw sonar returns on the display. These returns will often result in "arches" forming on the display, indicating potential targets. Due to the transducer beam angle, the distance to a fish decreases as the fish moves into the beam, and then increases as it moves out again, creating a Fish Arch when this distance change is shown on the display. Boat speed, chart speed, and the position of the fish within the sonar beam greatly affect the shape of the arch. Transducer Cone and Fish Arches To turn Fish ID+TM on or off: 1. Press the LEFT or RIGHT Cursor keys to turn the Fish ID+TM setting On or Off. (Off, On, Default = On) Sonar Menu Tab 42 Fish ID Sensitivity Fish ID Sensitivity adjusts the threshold of the Fish ID+TM detection algorithms. Selecting a higher setting allows weaker returns to be displayed as fish. Selecting a lower setting displays fewer fish from weak sonar returns. Fish ID+TM must be On for Fish ID Sensitivity to affect the ability of the Fishfinder to identify sonar returns as fish. Press the LEFT or RIGHT Cursor keys to change the Fish ID Sensitivity setting. (Low = 1, High = 10, Default = 5) Real Time Sonar (RTSTM) Window RTS WindowTM sets the RTS WindowTM to either Wide or Narrow, or turns it off in the Sonar View. The RTS WindowTM always updates at the fastest rate possible and only displays returns that are within the transducer beam. See What's on the Sonar Display for more information. RTS WindowTM (Wide) RTS WindowTM (Narrow) RTS WindowTM (Off) To change the RTS WindowTM setting: 1. Press the LEFT or RIGHT Cursor keys to change the RTS WindowTM setting. (Wide, Narrow, Off, Default = Narrow) 43 Sonar Menu Tab Bottom View Bottom View selects the method used to represent bottom and structure on the display. Structure ID® represents weak returns in blue and strong returns in red. WhiteLineTM highlights the strongest sonar returns in white resulting in a distinctive outline. See What's on the Sonar Display: Bottom Presentation for more information. Press the LEFT or RIGHT Cursor keys to change the Bottom View setting. [. . . ] Additionally, the receiver offers a wide "dynamic range" which provides the ability to receive very strong signals alternating with very weak signals, without the strong signal overwhelming the weak signal. TripLog: TripLog is a Humminbird® feature that provides an on-screen counter for Elapsed Time, Average Speed and Total Distance traveled, and requires a speed input to activate the feature. TripLog appears on the Big Digits View, and can be reset to zero through the TripLog menu. TrueArch®: TrueArch® is a Humminbird® feature that provides true fish arches, not artificial arches or symbols. [. . . ]
