Humminbird 587ci HD Waterproof Marine GPS and Chartplotter with Sounder

Timber, rocks, or even fish--watch it all take shape on crystal-clear, full-color 4.5" displays. With screens that size, it's easy to take advantage of versatile DualBeam PLUS Sonar and exclusive Humminbird SwitchFire technology. We're talking a beam sensitive enough to track a jig down to 70 feet and seperate fish as close as 2.5" apart. Find your way using built-in UniMap or up the ante with optional Lakemaster and Navionics cartography. Get all this technology in a convenient in-dash mount, or use our Tilt & Swivel Quick Disconnect Mounting System.
