Mine is sensitive to engine noise from passing power boats.  I have
decided that it's mostly the cavitation causing it, since the depthfinder
persists in resetting itself for several seconds after the power boat
and its noise is gone.  I might add that my transducer is several feet
away from my engine (more like 20 or so).
