As someone who’s gone from regular Panoptix to Livescope after a few solid years of using Panoptix, I think the regular Panoptix still has its time and place. If you are just searching for fish, or are running and gunning, the Panoptix still does everything I need. With a little bit of practice, you are easily able to pick out which fish are larger, and the GT10HN 2D transducer is great when you are fishing deeper water.
I will say though, the Livescope does give a much higher quality image, which is like going back to watch standard def tv after seeing high def.
