HUMMINBIRD 581I COMBO

Outstanding performance and incredible value come together in the 500 Series. See everything on the generous 5", 640V x 320H, FSTN LCD 16 level grayscale display. With a screen that size, it's easy to take advantage of the versatile Dual Beam sonar with exclusive Humminbird SwitchFire technology; sensitive enough to track a jig down to 70 feet, and separate fish as close as 2.5" apart. You can also choose between actual sonar returns or Humminbird's Fish ID+ target identification. All this in a new design perfect for in-dash or Tilt & Swivel Quick Disconnect Mounting System installation. 50-Channel internal GPS includes trackplotting, chartplotting, Humminbird UniMap and GPS speed. Depth to 800'.
