Maybe I'm just too dense to understand....<br /><br />The signal return from the transducer to the F/F represents a more-or-less horizontal circular plane under the T/D, right? A cross-section of the cone-shaped area where the bottom (or whatever) intersects the T/D signal?<br /><br />The display is a representation of a vertical plane, surface to bottom. <br /><br />So, the question is:<br />How does the F/F translate the horizontal plane to a vertical plane on the display? How does it "decide" which vertical cross-section of the T/D return to show? I mean, when I see structure or fish or bottom contours scrolling past on the display, how do I determine where they are in relation to the boat?<br /><br />I just couldn't find a website that explained it in language I could understand.<br /><br />Any insight would be appreciated.<br /><br />thanks,<br />jtw
