Selecting the Transducer Frequency
NOTE:
You cannot adjust the frequency for all sonar views and transducers.
You can select which frequencies appear on the sonar screen.
Always be aware of local regulations on sonar frequencies. For example, to protect orca whale pods, you might be prohibited from using frequencies between 50 to 80 khz within ½ mile of an orca whale pod. It is your responsibility to use the device in compliance with all applicable laws and ordinances.
