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.
Your 100 Series™ Fishing System represents targets detected in the 200 kHz narrow beam as Orange Fish Symbols.

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. This is useful for identifying smaller fish species or baitfish. Selecting a lower setting displays fewer fish from weak sonar returns. This is helpful when seeking larger species of fish. Fish ID Sensitivity is used in conjunction with Fish ID+TM. Fish ID+TM must be On for Fish ID Sensitivity to affect the ability of the Fishing System to identify sonar returns as fish.
To change the Fish ID Sensitivity setting:
1.Highlight Fish ID Sensitivity on the Sonar main menu.
2.Use the LEFT or RIGHT
Transducer Cone and Fish Arches
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
Real Time Sonar (RTS®) Window
RTS® Window sets the RTS® Window to either Wide or Narrow, or turns it off in the Sonar View. The RTS® Window always updates at the rate possible and only displays returns that are within the transducer beam. (See Real Time Sonar (RTS®) Window for additional detail).
