Use Wide Mode for maximum search area or Narrow Mode to hone in on the small stuff with laser precision.Down ImagingThe incredible images shown in Down Imaging are a result of high-frequency sonar beams transmitting in ultra-thin slices through the water column. The sonar returns from these beams produce a portrait-like snapshot of what lies beneath your boat. As you patrol the water, you'll see fish, reefs, timber, brush, bridge pilings, rocks and other structure or cover explode with stunning detail.Fish ID+When enabled, it uses advanced signal processing to interpret sonar returns and will display 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 size icons represent the intensity of the sonar return and provide an indicator of relative fish size.
