ELECTRICALNOISE
Amajorcause ofsonarproblems iselectrical noise. This usually appearsonthe sonar'sdisplayas randompatternsof dots or lines. In severecases, It can
completely coverthe screen with blackdots,orcause the unit operate erraticly, or not at all.

the batteryhelpseliminatenoiseproblems. Makecertain touse the in-line fuse supplied with the unitwhenwiringthe powercableto the battery.
Whenno noise appearson the sonarunit afterallofthe abovetests, then the
noise source is probably cavitation. Many novices or persons with limited experience make hasty sonarinstallations which functionperfectlyin shallow water, orwhenthe boatisatrest. Innearlyallcases, thecauseofthe malfunction
will bethe locationand/orangleofthe transducer. Theface ofthetransducer must beplacedin a location thathas asmooth flow ofwateratall boat speeds.
