[QUOTE="MN Fisher, post: 487673, member: 31421"] Just remember one thing about the CV - while the 2-D does send/receive in a cone so it shows things ahead and behind, the down-view is just a slice of that cone directly below and slightly to the sides of the transducer - like you took a triangular sheet of glass and dropped it point up in the water. What shows up as the 'current' item is just directly in line of the transducer. This is an older pic, but is of the Garmin GT-20 showing the coverage areas of 2-D and Down-scan. [ATTACH type="full" alt="newDIbeams_zps23dd749d.jpg"]110790._xfImport[/ATTACH] So your best bet of finding fish on the down-scan is to put it up front on the TM or some people mount the transducer to a pole as when the TM turns, it shifts the angle that the down-scan is looking - if you're making a 45-degree port (left) turn, the scanning looks like this [ATTACH type="full" alt="newDIbeams_zps23dd749d-45.jpg"]110791._xfImport[/ATTACH] [/QUOTE]
