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.
Your 100 Series™ Fishing System represents targets detected in the 200 kHz narrow
beam as Orange Fish Symbols.
When Fish ID+
TM
is turned off, the 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+ 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+
