There are several main conditions or sources of possible interference that may cause problems w ith the quality of t he in formation displayed on the control head. Look in the following table for some symptoms of display problems and possible solutions:

Problem

Possible Cause

The control head loses If the power output of your boat’s engine is unregulated,

power at high speeds. the co ntrol hea d ma y b e prot ecting i tself u sing i ts over-voltage pro tection feat ure. M ake s ure t he inp ut voltage does not exceed 20 Volts.

When the boat moves at higher speeds, the bottom disappears or suddenly weakens, or the display contains gaps.

The transducer position may need to be adjusted. A mix of air and water flowing around the tr ansducer (cavitation) may be interfering with the interpretation of sonar data. See your Installation Guide for suggestions on adjusting the transducer position.

Electrical noise from the boat’s engine may be interfering with sonar reception. See Finding the Cause of Noise for more information.

There are no fish detected, even when you know they are in the water under the boat, or sonar readings seem weak or faulty.

Sonar r eadings may be affected if the transducer is not positioned correctly (i.e. mounted at an angle, not straight down), or there is some kind of mechanical interference, either because it is mounted inside a hull that is too thick for p roper son ar transmission, the bond betwe en th e transducer a nd the hull is not a irtight, or because the transducer is dirty. Check with your Installation Guide for guidance on re-positioning the transducer, and make sure the transducer is clean.

Low battery voltage may be affecting the power of signal transmission.

Electrical noise from the boat’s engine may be interfering with sonar reception. See Finding the Cause of Noise for more information.
