2 of my friends have the 2020 helix 9. They are ALWAYS f'ing with the settings while I am catching fish on my LX-5.

So this is the mode I run the most on my finder while fishing, usually trolling for perch and walleye and such. The side imaging helps with planner boards and such to see fish off to the side and try and get your boards going over that spot, with all the modes need about 3 finders to be watching with all that is available cool technology though then there is the live imaging now that everyone is using for the bass fishing and such to watch the fish where you are casting.
I have a helix7 mega si with GPS still trying to learn all features, like it so far.
