Hi there
I have been spending more time trying to improve my skills using my Furuno 585 and have been using manual gain to improve the display and mark marlin. This has been simple to do when drifting or slowly cruising in calm water. However when it gets rougher the pic changes and shows more clutter and produces many "gaps" on the screen. Is this normal or is it likely that the transducer is not deep enough in the water? If not, how can I reduce the number of gaps on the screen?
Many thanks
