On the FishFinder display the bottom graph is “drawn” after the FishFinder

receives several echoes. This has the effect of showing a record of the

bottom contour. The A-scope displays raw sonar data directly from the

transducer beam. This gives you a “real time” image of fish and bottom

structure directly below the transducer. This function is very useful in

showing the strength of the echo returned from a fish. Stronger fish

echoes on the A-scope display will appear wider; weaker echoes appear

as narrow bands closer to the horizontal center of the A-scope image.
