    I have a hummingbird 190c in the bow of my boat and was wondering what the chart speed should be set at?? Right now I have it at four but not sure if it is set right… Could someone enlighten me Thanks

    It is just a personal preference adjustment. Although the faster you are traveling the higher your adjustment

    Run my 788ci on the bow and 997 at the helm on 4, 99% of the time.
