Note 1: SonarView will allow range settings out to 200m. Rather than inflate the range specifications here we use ranges at which we have comfortably identified targets.

Note 2: Far Field distance is the range beyond which the beam width specification is valid. At nearer distances the effective beam width gets wider, and sidelobes get larger.

Note 3: This is the nominal theoretical 2-way (transmit and receive) 3dB beam width.
