include basic StructureScan options.
Gain for both images can be adjusted as described on “Adjusting color and gain
settings” on page 52.

The ping speed
The Ping Speed controls the rate the transducer transmits into the water. A high ping speed
will make the image move fast on the screen, while a low ping speed will present a longer
history on the screen. The reverberation potentially caused by too high ping speed can cause
interference on the screen.
Clarity
Wave action, boat wakes and temperature inversion can cause on-screen clutter near the
surface.
The surface clarity option reduces surface clutter by decreasing the sensitivity of the receiver
near the surface.
