Review & Description
Outstanding performance and incredible value come together in the Humminbird 581i. See everything on the 5" monochrome display 640 vertical pixels for a crystal clear view. With a screen that size, it's easy to take advantage of the versatile DualBeam Sonar with exclusive Humminbird SwitchFire technology, sensitive enought to track a jig down to 70 feet and seperate fish as close as 2.5" apart. You can also enable Humminbird's Fish ID+ target identification system to convert sonar returns into easy-to-read icons. Get all this technology in a convenient in-dash mount, or use our Tilt & Swivel Disconnect Mounting System. With the versatile, flexible the 581i, the toughest decision you'll make is when to call it a day. This unit also features a 50 channel GPS. This unit includes the head unit (screen), mounting base, internal GPS, transducer, power cord, necessary cables, and instruction manual.
