The down image view is the same orientation as the 2d view...new data is painted onto the right edge and old data scrolls to the left...(imagine your body was actually standing on the lake bottom and looking sideways under your xducer...bottom of the lake at the bottom of the display...surface of the water at the top of the display...)

The xducer is (in fact) looking down...so the processor takes that info under the xducer and re-arranges the data into an image format (2d or DI)..like you were underwater and looking sideways thru the water column...
