<p>PROBLEM TO BE SOLVED: To provide a fishfinder which displays the depths of sounding cursor positions of both screens, where different depth ranges are displayed while divided into the right and left, with one sounding cursor. SOLUTION: This fish finder can be constituted only by a irreducible sounding cursor moving means by providing a means which makes two sounding cursor depth displays on both the screens respectively. Consequently, the complexity of a console panel is eliminated to provide the fish finder which eliminates the complexity of its console panel and a factor of misoperation, lowers the cost, and facilitates measuring operation.</p> |
