Northstar 457 Explorer Features
Like its big brother the Explorer 467, the 457 reveals water column detail like never before, thanks to dual frequency sonar paired with an outstanding 640 x 480 pixel color display.
Having a dual frequency fishfinder allows you to select optimum performance for either deep or shallow water. As well as the standard mixed frequency display, the Explorer 467 and Explorer 457 allows you to select either a narrow beam or a wide angle beam.
