rockbass try looking at Humminbird :: Fishfinder :: Depth Finder :: GPS Chartplotters :: Side Imaging Sonar Technology :: Marine Fish Finders and go to the support column. click on it and in the right hand column drop down will be a electric interference then click on it and a good description will be on it! Better then what i can tell you?
