Hi Joel

Are you using the same time another sonar?
It can also be interference from the electrical system (power supply). According to one possible answer sepeate use battery for power supply.

j2000,
 
I get the same type of noise and I know it's radiated from either the engin's ignition system or charging system. I use separate batteries. The stains do not show on the display while on water because they are filtered away by the unit. Humviewer shows the raw recording so all types of disturbancies are shown. If you look carefully, you will see there is a symmetry in the stain pattern between left and right SI views.
