Last December (2021), the state of KS equipped 6 boats, 3 with Live scope, 3 with std sonar and rounded up 40 participants in 2-man teams, divided Cedar Bluff into north and south zones and spent 3 weeks using anglers 2 days at a time fishing with live scope on one day and std sonar the next.
I was able to be a part of this. When the Data was published, it was determined that Live scope had no affect on catch rate, in fact it was reversed, more fish were caught with std sonar than Live scope. We also were not fishing for spoonbill. If they figure that out, it is what it is.
Even with Live scope, you still don't know (on most sport fish species) if they are crappie, shad, carp, whitebass, etc.. It's real easy to get hung up on trying to catch a fish that is not what you think it might be.
