Northstar Explorer Color Fishfinder
If there are fish to be found, you’ll find them with a Northstar Explorer dedicated fishfinder.
Northstar’s Explorer range of color fishfinders have sophisticated sounder technology. With our ease-of-use engineering, in a range of sizes and single/dual frequency combinations to suit your needs.
Our bright HI-RES displays boast 640X480 pixels making these dedicated fishfinders a stunning addtion to a boat of any size.
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
