The Northstar fishfinder can be used to find fish o locate features on the bottom such as reefs or wrecks and to help recognize favourite fishing spots from the bottom profile e Northstar fishfinder can also assist with navigation by providing depth information to help identify the depth contours marked on Important It is vital to the performance of the fishfinder that the transducer is installed in the best location Please follow the installation instructions very carefully charts The Explorer 443d 443df is particularly suited to work with the Explorer 538 The two instruments can be connected together using either NavBus or NMEA so they can share data only applies to Explorer 443df IMPORTANT NOTE ON USE While any fishfinder can be used as an aid to navigation accuracy can be influenced by many factors including the location of the transducer It is the user s responsibility to ensure that the Explorer 443d 443df is installed and used correctly With the optional fuel kit the Explorer 443df also becomes a sophisticated and easy to use uel computer All of the Northstar 400 Series fishfinders use new proprietary SBN Technology for sonar processing to improve Signal enhancement Bottom recognition and Noise rejection SBN I Technology uses digital adaptive filter algorithms to enhance all returned signals At the same time SBN Technology uses active noise control to reje
