Humminbird 597ci HD Combo Fishfinder

• Switchfire Sonar
  When you hit the water, you don't limit yourself to one bait. So why limit your sonar? Exclusive Humminbird® SwitchFire Sonar gives you the power to choose how returns are displayed. With two unique modes, you have complete control to adjust with the fishing conditions, making our down-looking sonar an even more valuable fishfinding tool. With SwitchFire Sonar you'll never fish the same way again. Just another way Humminbird® is simply, clearly, better.
• Split Screen Zoom
  Split Screen Zoom increases the displayed resolution to separate sonar returns that are very close together. In this view, the display is split to show a narrow slice of the full range view on the right and the zoomed view on the left. The zoom preview box on the right tracks the bottom in the full range view.
• Split Screen Bottom Lock
• Wide Narrow Cone Split Screen
  This screen separates the sonar data using the two primary user selectable down-looking beams simultaneously in split screen. Fish ID feature shown indicates depth and in which beam fish are detected by changing color, size, and/or orientation of the fish icon.
• Freeze Frame with the ability to Mark Structure on Sonar
  Pressing any arrow on the four-way cursor control instantly stops the sonar graphic display to allow a closer inspection of submerged structure, bait fish, and underwater contours. Movable cursor feature allows you to instantly discern depth of any sonar return and mark waypoints from the sonar screen for navigation. Pressing the EXIT key will exit the freeze frame and the display will start to resume scrolling. Mark the location of fish-attracting structure, bottom transitions, or any feature anywhere on traditional sonar with the Sonar Cursor.
• Selective Fish ID+
  Fish ID+ uses advanced sonar processing to interpret 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 that has been classified as being a fish. Three different fish icons represent intensity of the sonar return, and provide an indicator of relative fish size.

  DualBeam PLUS equipped models represent targets detected in the 200kHz narrow beam as Orange Fish Symbols, and represent targets detected in the 83kHz wide beam as Blue Fish Symbols.

• Real Time Sonar RTS Window
  A Real Time Sonar (RTS®) Window appears on the right side of the display in the Sonar View only. The RTS Window always updates at the fastest rate possible and shows only the returns from the bottom, structure, and fish that are within the transducer beam. The RTS window can be displayed as narrow (standard), wide, or off.
• Sonar Echo Enhancement
• TrueArch Technology
  Many competitive sonar products commonly use post processing software to "enhance" the arching effect produced when suspended targets enter and leave a sonar beam. This additional processing can slow down performance and exaggerate the information displayed. Humminbird’s TrueArch Technology utilizes parallel processing of sonar data to eliminate unwanted interference and noise and reveal unaltered sonar echoes resulting in true arches of fish targets. This helps anglers more quickly discern the size and depth of fish targets.
• 3D Chart View
• Large Digits View
  Also known as Big Digits View provides digital data in a large, easy-to-see format. Depth is always displayed. Readouts for temperature, speed, and Triplog information are displayed automatically if the appropriate accessory is connected. The Triplog shows distance traveled, average speed, and time elapsed since the Triplog was last reset. The digital readouts in the Big Digits View cannot be customized.
• Custom View Selections
  User selectable views 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
  Advanced User Mode allows customization of digital readouts. Select from available options on all 5 different readout boxes.
• Selectable Display Colors
  Sonar Colors allows you to select which color palette you would like to use for the display. There are eight choices; Standard, Gray, Inverse, Green, Palette 1, Palette 2, Palette 3. (White is the standard Background Color) Background Colors can be changed between White(standard), Blue, and Black.
• Selectable Background Colors
  There are three different Background choices for a combination of twelve different possibilities for Display Colors. GPS Views only allow the Background to be changed.
• Triplog
  The Triplog is a selectable readout and will only appear in the menu if a Speed Accessory, GPS or Paddlewheel, is connected. The Triplog provides average speed, distance traveled, and elapsed time information.
• X-Press Menu System
  The X-Press Menu provides quick access to the settings most frequently used. Press the Menu key once to access the X-Press menu. This simple and convenient feature saves valuable time when you want to change the most used settings. Spend more time fishing and less time adjusting. Press the menu key a second time to access the main menu.
