9. The display shows many black dots at high speeds and high
GAIN settings.
You are seeing noise or interference caused by one of several sources.
Noise can be caused by other electronic devices. Turn off any nearby
electronics and see if the problem goes away. Noise can also be caused
by the engine. If engine noise is causing the interference, the problem
will intensify at higher RPMs. Increase the engine speed with the boat
stationary to isolate this cause. Propeller cavitation can appear as noise
on-screen. If the transducer is mounted too close to the propeller, the
turbulence generated can interfere with the sonar signal. Ensure that the
transducer is mounted at least 15" from the prop. At higher speeds use
the FILTER selected to ON to reduce ambient noise.
