Side Imaging on the Humminbird 998c HD SI may have been the biggest thing to hit the fish finder world since the arrival of a combo GPS/sonar. Humminbird developed Side Imaging in the mid-2000s and captured what many fisherman had always wanted: a picture of what’s under the surface of the water. With the Side Imaging on your Humminbird 998c, your fish finder can show amazing detail of the bottom of the lake up to 240’ wide, to the left and right of the boat. Curious what those cribs you found on your sonar look like? Cruise over them with the Humminbird 998c and get a clear view of what’s actually down there. You can even recognize fish within the structure! Cruise around your favorite fishing holes and really learn what’s down there.
If you thought Side Imaging on the Humminbird 998c was cool, now they have come out with Down Imaging. Down Imaging creates “snapshots” while emitting super thin slices of high-frequency sound waves. This gives you the ability to see the structure with a side view, even though you are going over the top of it. If you turn on Narrow Mode, it 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. Getting the picture why you need a Humminbird 998c yet?
Of all the amazing aspects of the Humminbird 998c SI fish finder, SwitchFire ranks right at the top. SwitchFire sonar modes let you adjust the view on the screen to the fishing conditions. You have two modes to choose from. Max Mode and Clear Mode.
In Max Mode, sonar returns really come to life from the screen, in amazing detail. You’ll see the tiniest subsurface object (even thermoclines and water currents) for complete underwater coverage. Since Max Mode returns so much information on the screen, it may be difficult for an unexperienced user to interpret what they see on the screen.
In SwitchFire 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 for reducing undesired clutter in the water column. Clear Mode will be very beneficial to a newer user of the Humminbird 998c or people that have a tough time interpreting what they see on the sonar screen.
With three soft-key preset buttons on your Humminbird 998c HD, you can create multiple views with GPS/Side Imaging or Side Imaging/sonar or GPS/sonar, or many more. It’s easily customizable for ease of operation. The large screen makes it easy to see the detail of the screen as well.
Memory, GPS, Mapping
The Humminbird 998c’s dual SD card slot expands unit memory, giving you the oppurtunity to save screenshots of your fish finder to share with friends and family. Forums on the internet are great places to meet with other fisherman to discuss and interpret your screenshots, as well as everyone else’s.
The 50-channel external GPS will keep you locked in on your location to make sure you don’t slip off the magic fishin spot. And to help you find the safe path to the fishing spot, the Humminbird 998c fish finder is also LakeMaster and Navionics compatible-giving you a great visual of where you are on the water.
