FISH ID SENSITIVITY

Fish ID Sensitivity adjusts the threshold of the Fish ID+™ 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 Sensitivity is used in conjunction with Fish ID+™. Fish ID+™ must be On for Fish Sensitivity to affect the ability of the 900 Series™

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 Getting Started - Using Your 900 Series™: Real Time Sonar [RTS®] Window for more information.)

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 Sensitivity setting. (Low = 1, High = 10, Default = 5)

RTS® Window (Wide)

To change the RTS® Window setting:

1.Highlight RTS® Window on the Sonar main menu.

2.Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the RTS® Window setting. (Wide, Narrow, Off, Default = Narrow)

FISH ID 3D REFERENCE

Fish ID 3D Reference selects the reference line style used in the 3D Sonar View. Up draws a line from the fish icon to the surface plane, Down draws a line from the fish icon to the bottom contour, and Both draws both lines.

To change the Fish ID 3D Reference setting:

1.Highlight 3D Fish ID Reference Line on the Sonar main menu.

2.Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Fish ID 3D Reference setting. (Surface, Both, Bottom, Default = Bottom)
