Humminbird® 598CI HD SI High-Definition Side Imaging™ Combo GPS &Q Color Fishfinder

'Like' or Google+ this item.

Side Imaging™ for selectable narrow / wide sonar and true 180° coverage. Down Imaging™ for a clear view from the bottom of the boat straight down. Add it together, and you've got the most complete picture ever of what's going on under the surface. It's bad news for fish. And with full-color, high-def clarity, built-in GPS function, and pre-bundles maps included, it's one of the best performers on the water today!

Side Imaging Sonar - Get the best of both worlds with selectable narrow and wide beams for true 180° coverage. It's everything you need to master the lake or sea bottom

Down Imaging Sonar - Provides picture-like images of structure below your boat by combining a traditional down-looking sonar view with side imaging technology. Observe Down Imaging side-by-side on your screen with SwitchFire™ (explained below), or on a 3-way view.

DualBeam PLUS™ - 2 beams, best of both worlds! A narrow beam is optimized for bottom and structure detail below your boat, while a beam casts a wider net, searching for fish and structure around your boat. View them side-by-side onscreen or combine the images into 1 comprehensive view!

Built-in GPS Function - GPS track-plotting and chart-plotting made easier than ever before! With push-button simplicity, you'll be able to track GPS speed, mark 2,500 waypoints, chart 50 routes, and mark 20,000 points of interest.

SwitchFire - Gives you a real time, customized look below the water's surface with 2 different modes: "Max Mode" and "Clear Mode".

Max Mode detects even the slightest returns, displaying them on-screen in full detail, and helping you identify variables like thermaclimes, plankton and baitfish populations, structure and, of course, game fish. Max Mode is great for jigging, too, since its incredible detail allows you to see your jig on-screen. This complete picture of the action below your boat lets you tailor your approach to match the conditions and catch more fish.

Clear Mode offers a crisp, uncluttered representation of structure and fish...great for fishing in shallow water. Clear Mode filters out weaker returns like silt and debris, displaying only stronger signals like bottom contour, structure, schools of baitfish and individual game fish.

Pre-loaded UniMap - Includes UniMap™ bundle covering the continental U.S. coastline, inland lakes and rivers at 30 meters per pixel resolution. UniMap™ gives you an accurate chart almost anywhere you travel in the United States.

More Advanced Sonar features:

  • Split Screen Zoom increases the displayed resolution to separate sonar returns that are very close together
  • Split Screen Bottom Lock
  • Wide / Narrow Cone Split Screen separates the sonar data using the two primary user selectable down-looking beams simultaneously in split screen
  • Instant Image Update... the sonar chart updates in real time to show the latest information on the sonar screen
  • Freeze Frame with the ability to mark structure on sonar. Inspect and mark submerged structure, bait fish, and underwater contours with special Sonar Cursor
  • Selective Fish ID+ interprets sonar returns and displays a fish symbol when very selective requirements are met. When a fish is detected, a fish icon and its depth are displayed above the return. 3 different fish icons represent intensity of the sonar return, and provide an indicator of relative fish size.

User-friendly features:

  • X-Press™ Menu System provides quick access to the settings most frequently used
  • 3D Chart View
  • Large Digits View provides digital data in a large, easy-to-see format
  • Custom View Selections allows you to see only the views that you want, giving you the flexibility to access the information you need quickly and easily
  • Custom Digital Readout Selection allows customization of digital readout
  • Temperature Alarm allows you to preset and display an alarm when a desired temperature is reached.
