Interference

Adjusts the sensitivity to reduce the effects of interference from nearby 

sources of noise. The lowest interference setting that achieves the desired 

improvement should be used to remove interference from the screen. 

Correcting installation issues that cause noise is the best way to eliminate 

interference.

Interference from other acoustic equipment operating nearby or other 

electronic equipment on your boat may appear on the display as shown in 

the figures below. You may reduce the effect with a noise limiter. There are 

varying degrees of interference. Minor interference or noise can be stray 

signals that can look like actual targets. Severe noise can completely fill the 

screen and make depth readings impossible. To counter interference, you 

have to first identify the type of interference. Although most noises can be 

eliminated with fairly simple techniques, some interferences can only be 

reduced to a more acceptable level.

1. Sonar Cross-Talk interference

: caused by nearby fishfinder(s) of similar 

transmit frequency. It will appear as the diagonal lines across the screen. 

When two fishfinder’s transducer cones intersect, the units will not be able 

to tell the signals apart. See figure (A) below.

2. Electromagnetic Interference (EMI)

: caused by powerful electromagnetic 

waves radiated from electric equipment and wirings. The electromagnetic 

waves are then absorbed by the transducer cable and appear as vertical 

lines on the screen. See figure (B) below.

(A) Interference from other sonar

(B) Electrical interference

Surface Noise

When the sea is rough or the ship passes over a wave, surface noise may 

appear at the top of the screen. It can be suppressed with the CLUTTER 

function which hides surface noise to help reduce clutter. Wider beam widths 

(lower frequencies) can show more targets, but can generate more surface 

noise.
