NOTE: This configuration of the Northstar Explorer 457 is packaged with a plastic dual-frequency transom mount transducer that provides depth, temperature, and speed readings. If you would prefer another transducer type, or already have one, click here to see the unit without it.
If there are fish to be found, you'll find them with a Northstar Explorer dedicated fishfinder.
The Northstar Explorer range of color fishfinders have sophisticated sounder technology. With Northstar's ease-of-use engineering, in a range of sizes and single/dual frequency combinations to suit your needs. The bright HI-RES displays of the Explorer 467 and 457 boast 640X480 pixels, making these dedicated fishfinders a stunning addtion to a boat of any size.
Northstar Explorer 457 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.
The 457 maximizes helm space and value, by putting all that power in a 5" screen.
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.
VGA - Four Times the Pixels!
The Vertical Value: When bottom detail becomes critical in identifying species' habitat, or for navigating a way through coral reefs and uncharted channels, you need greater detail in the vertical column. The Explorer 467 and 457 have 4 times the screen pixels of previous large screen models, making them an ideal choice for all boaters needing detailed information.
High detail also means better target definition for fishing. Low-resolution devices might identify schools of fish, but high-resolution devices will aid in determining if they are small schools of big fish, or large schools of small fish.
