Down ImagingTM technology. See all the happenings below your boat. Timber, brush, bridge pilings, rocks and any other structure will pop with stunning detail as you patrol the water.
How? 1. "Snapshots" are created with high-frequency sound waves emitted in razor thin slices. 2. Sonar returns from these waves create an instant "snapshot" below the boat. 3. Narrow Mode analyzes the returns to verify the position of the echoes to ensure Down Imaging only shows you structure and activity beneath you, and not off to one side or another. Quickly identify structure with Down ImagingTM, while using 2D to locate and target fish. Together, they take the guesswork out of sonar fishfinding.
Humminbird SwitchFireTM Sonar gives you the power to choose how returns are displayed. With three unique modes, you have complete control to adjust with the fishing conditions, making the down-looking sonar an even more valuable fishfinding tool. Get incredible detail in Max Mode.
Watch as the sonar returns explode from the screen in amazing detail. You'll see the tiniest subsurface object-even thermoclines and water currents - for complete underwater coverage. And for easy viewing in rough water, there's Clear Mode. Time Variable Gain (TVG) software sifts through sonar returns to display only fish and structure. Great for fishing in shallow and rough water, or reducing undesired clutter in the water column. 3-color Palette Mode provides even more flexibility on the water to deal with overcast or full-sun conditions.
