Humminbird Fish Finder 597ci HD DI Combo
The 597ci is a reliable GPS unit for finding your way around the water, but it truly excels when what you're really searching for is fish. Two beams of sonar are emitted from the unit, wide for extensive coverage of the area at large and narrow for clear definition of what is detected.
The full-color, five-inch display lets you view both modes in split screen view or combine them together for a real-time assessment of what the sonar has picked up. You can even zoom and freeze-frame to get an even better look at what lies beneath the surface. If and when fish are detected you can set filters to detect certain characteristics and sizes of fish with specific icons that illuminate to alert you specifications have been met and there's something worth catching.
The unimap included with the device will show you basics of most shorelines and is compatible with more detailed navionic cards for true navigational capability. The 597ci allows you to save up to 3,000 waypoints and there's enough memory to store 20,000 track points and save 50 tracks.
