I have a HDS 5 in dash on 190 CX,added Structure scan last spring..Absolutely love it ,best money I ever spent on electronics..When I use side scan, I just use either side scan set on 60 ft.(switch left or right side, depending on which bank Im fishingt.Have benefefit of a large screen without the expense .Also it fits in dash.I dont use it much fishing shallow banks,but ledges and structure,you'll wonder how you ever fished without it.
