383c transducer gives nothing but noisy red feedback at medium or high speeds
My transducer is installed as instructed but when at mediium to high speeds it just shows a bunch of garbage. Red feedback across the entire screen. Any ideas on what adjustment mat be needed? Up, Down, ?? Thanks

If it works at low speeds fine but has problems at higher speeds, basically you need to lower the transducer down further as it is lifted by the boat at higher speeds, or is getting caught in the turbulence of surface water created at higher speed. Lower the transducer a half inch at a time and re-test.
