Sounder Mode

This feature is only available with the Sounder module

This buttons adjusts the operating mode of the Sounder such as frequency, Zoom Mode, etc...

  • HF / LF : Select the operating frequency of the sounder. If the sounder is in Dual Frequency mode (both HF and LF displayed on screen), clicking on this button will inverse the side of the operating frequency.

  • Single Frequency: Set the Sounder in Single Frequency mode. This will only display one sounder echogram on the screen. Select either HF or LF from the menu above.

Note: If AccuFish or Bottom Discrimination is selected, the sounder will transmit HF and LF even if the mode appears to be set to Single Frequency only. This is because AccuFish and Bottom Discrimination need both frequencies in order to work. If you want the sounder to only operate in one frequency, make sure to disable AccuFish and Bottom Discrimination.

  • Dual Frequency: Set the Sounder in Dual Frequency mode. This will display two sounder echogram on the screen (one for the Low Frequency and the other for High Frequency). When operating in Dual Frequency, the range of both frequencies is synchronized. To inverse the side of the HF and LF, select the "HF" or "LF" button above.

  • Bottom Lock: Set the Sounder in Bottom Lock. Please refer to Sounder Display Mode for more information.

  • Marker Zoom: Set the Sounder in Marker zoom and the Marker Zoom is displayed on the left half of the screen . This mode is useful for determining the size of fish in mid-water. Please refer to the Sounder options for more information.

  • Split Range: Enables the sounder's separate ranges for low- and  high-frequency diplays. Note that ACCU-FISH will be disabled when the split rane is use. Please refer to the Sounder options for more information.

  • Auto Range: Enables the Sounder Auto-Range. When set, the sounder will attempt to track the bottom and adjust its range automatically.
