I've had my HDS5 for a few months and am still struggling with trying to find setting that work well for me. 83/200hz wsbl transducer that is selected in settings. I fish coastal BC 2-300ft water (ocean) and am constantly changing from 83hz to 200hz and various pallates and messing with the auto sensitivity feature to manual sensitivity and continue to struggle. All the pallates i use end up "filled" with color (looks like interference) I've tried to bring down the sensitivity but then lose detail. I've seen on the Lowrance website the beautiful screenshots and i have never been able to get anything close to that. I think i am seeing fish arches at times but there is so much color on my screen it's hard to see. Bottom shows up perfectly although at speed i lose it (dealing with that problem....) i'm really frustrated, have read through the manual a few times, and know that the HDS is fine...it's operator error!!!! Help! thanks
