One thing that when I upgraded my unit on my boat I looked around and looked into the Hummingbird with auto chart live so I could map some of the lakes that are around me without any maps available and that has helped me on specific spots fishing for Walleye as I can map them out and then stay on the contour the fish are hanging on easier, but the one thing that has helped me the most is the tracks while trolling, once I catch some fish I can turn around and go right back over where I caught the fish and stay where they are without throwing out any markers and showing people what I am doing and have them move in and be able to follow my course. That is the best thing I would say the Helix has done for me and I am still learning the side imaging and all that it has the capability of doing, the Mega Live and Panoptic are all cool and have watched guys using them around me and having the capability to watch your bottom bouncer or crank and see how the fish are reacting to it is cool as well, just depends on how much money you have to get into the game.
