This view shows all echoes in the traditional sonar graph display.You can view echoes from any two 384 kHz transducer elements, or the 192 kHz transducer. (Note: 192 kHz operation requires an optional 192 kHz trans- ducer.) To select the transducer element and place the X-70A 3D into the 2D mode, press the WINDOWS key. Next, press the key next to the "2D 384 kHz" label or the "2D 192 kHz" label. The screen shown at right ap- pears.
