thank you for the help!! and i was really wanting a side imaging, down scan, 2d, and gps but after watching youtube videos last night for a couple hours on fish finders the side imaging honestly kind of confused me on how the layout is on the screen! it may have been the video i watched of it being explained that confused me im not really sure! But with hummingbird im pretty sure the unit i looked at had all of that but i found a lowrance with down scan, 2d, and gps elite 7 so a bigger screen for a little cheaper than the hummingbird just no side imaging which im not sure i need! i really want it but im not sure i can really understand it! and if you have side and down imaging and everything on your fish finder why do you sight fish? do you just know the lake well enough?
