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 100 SeriesTM 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 4-WAY Cursor Control keys to change the Fish ID Sensitivity setting. (Low = 1, High = 10, Default = 5)

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 fastest rate possible and only displays returns that are within the transducer beam. (See Real Time Sonar (RTS®) Window for more information.)
