Higher accuracy of depth and speed calculation
The transducer calculates the beam angle into the sea based on type of transducer and sea condition.
The calculation of speed and depth will be more accurate with:
• “Xducer Con” set to “A/B” with sensor DL850S27G-SB. “Screen Calibration”, “Menu 4”
• “salinity” “Screen Calibration”, “Menu 3”
• “temperature” Automatic from temperature sensor
• “Sound Surf” “Screen Calibration”, “Menu 4” set to “auto”
• “Sound Surf” “Screen Calibration”, “Menu 4” set to “auto”
