You really need both. Livescope will most likely be at the bow and then what will you have at the console? SI is a valuable tool for covering a lot of water and finding structure. My suggestion is get livescope and then you’ll have to get a display for it. When you get your display I would recommend at least the 93SV UHD and get it with the GT56 transducer. Then later on just get another display without transducer. This is what I did.
