Humminbird 898c Features

Side Imaging Sonar, with its clear, picture-like images of fish, the bottom and structure, is great structure-finding tool and with its massive coverage (480 feet from side to side) one can scan in mere minutes what used to take hours.

Humminbird Side Imaging Sonar uses very thin beam to take a 'sonar snapshot' of the area up to 240 ft. to the left and right of current location. The return image for this slice is then added to the images taken immediately before and after to build very detailed view of the bottom.

Humminbird has pointed their Side Imaging technology in a new direction: straight down. Now one can see the detail of what is happening below your boat. Timber, brush, bridge pilings, rocks and any other structure will be shown in great detail as one patrol the water.

Get the best of both worlds, with selectable narrow and wide beams one can view individually, or melded into one display. A precision 20° beam provides high accuracy returns of fish, structure, and bottom profile. The wider 60° beam provides greater coverage for fish and bait fish. One can view the two beams separately, side by side, or blended together for the most complete picture.

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.

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.

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.

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 shows fish, bait, and more - even watch vertical jigging on-screen. This is possible through advanced sonar processing and provides the details you want and need. It's important to know what depth the fish are located and equally important to be able to place your lure at that precise depth. Be careful! You may jerk the rod early while watching the screen instead of waiting for the actual bite.

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.

Humminbird has upgraded the free, built-in cartography software on the 800 series Combo models. All-new ContourXD by Navionics is an enhanced, professional mapping package. With over 3,000 U.S. lake maps in the database, one will be able to find a lake close to any location one might want to wet a line. As an added bonus, ContourXD maps will feature depth contour lines, so one can find all the drops, bumps and channels holding fish. The maps will also include U.S. lights/markers, and major roads and interstates.

Long story short: this is complex, not very cheap, piece of electronics that has numerous features that requires some time to get used to - be sure to go through the manual, even few times before going for the first fishing trip. It is good practice to download a manual before buying and verify that this sonar/gps/chartplotter etc can do what you want it to do. And it can do many things :)
