You are seeing noise or interference caused by one of several sources. Noise can be
caused by electronic devices. Turn off any nearby electronics and see if the problem
goes away. Noise can be caused by the the engine. If engine noise is causing the
interference, the problem will intensify at higher RPMs. lncrease the enqine speed
with the boat stationary to isolate this cause. Propeller cavitation can aIso appear as
noise on the display. If the transducer is mounted too close to the propeller, the
turbuIence generated can interfere with fhe sonar signal. Make sure that the
transducer is mounted at least 15"
(380mm) from the propeller.
