Looking to upgrade my fish finder. Does anyone have any experience with, or opinions on Lowrance Elite 7 HDI? It has a chartplotter, regular sonar, and DownScan imaging. Or Lowrance Elite 7X HDI (regular sonar, DownScan imaging, no chartplotter). I already have a stand-alone chartplotter, but the Lowrance model that has a chartplotter built in allows you to find a structure and then create a waypoint for it. And for the transducer, choices of 50/200 kHz (good to 2,500 ft.) or 83/200 (good to 1,000 feet). While I won't be fishing anywhere near 1,000 or more feet, it might be good to know when I'm at or over 1,000 feet when looking to put out my shrimp pots. Or any other brands/models that you have and have opinions on would be helpful. Especially interested in people's experience with the DownScan feature. Thanks.
