Fish ID+™
Fish ID+™
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™ Sonar models represent targets detected in the 200 kHz narrow beam as
Orange Fish Symbols, and represent targets detected in the 83 kHz wide beam as Blue Shaded
Fish Symbols.
When Fish ID+™ is turned off, the Matrix™ 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+™ on or off:
1. Highlight Fish ID+ on the Sonar main menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to turn the Fish ID+™ setting On or Off.

Beam Select
Beam Select
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. 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 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 and the Big Digits 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 and the Big Digits 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 200 kHz beam, the
83 kHz beam or the 200/83 kHz beam. (200/83 kHz, 200 kHz, 83 kHz, Default = 83 kHz)
