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 PLUS
TM
Sonar models represent targets detected in the 200 kHz narrow
beam as Shaded Fish Symbols, and represent targets detected in the 83 kHz wide beam
as Hollow Fish Symbols.
When Fish ID+
TM
is turned off, the 300 Series
TM
Fishing System 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.
To turn Fish ID+

sets which sonar returns from the
transducer will be displayed on the screen.
When set to
200/83 kHz
, the returns from both beams are blended by starting with the
83 kHz wide beam return, dimming it, and then overlaying it with the 200 kHz narrow
beam return. The darker 200 kHz narrow beam sonar returns will stand out from the
paler 83 kHz wide beam sonar returns. The Split Sonar View continues to display the
sonar returns from each beam in their respective windows. The blended information is
shown in the Sonar View, Sonar Zoom View, and the Big Digits View. The RTS® Window
in the Sonar View and the Circular Flasher View will only show the returns from the 200
kHz narrow beam.
When set to
200 kHz
, only the returns from the 200 kHz narrow beam will be displayed
in the Sonar View, the Sonar Zoom View, the Big Digits View and the Circular Flasher
View. The Split Sonar View will continue to display returns from both beams in their
respective windows. The RTS® Window in the Sonar View will display the returns from
the 200 kHz narrow beam.
When set to
83 kHz
, the returns from the 83 kHz wide beam will be displayed in the
Sonar View, the Sonar Zoom View, the Big Digits View and the Circular Flasher View.
The Split Sonar View will continue to display returns from both beams in their
respective windows. The RTS® Window will display the returns from the 83 kHz wide
beam.
To use Beam Select:
1. Highlight Beam Select on the Sonar main menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to select either the 83 kHz
beam, the 200 kHz beam, or the 200/83 kHz beam. (200/83 kHz, 200 kHz,
83 kHz, Default = 200 kHz)
