Down Imaging
Humminbird has pointed their Side Imaging technology in a new direction: straight down. Now you can see the detail of what is happening below your boat. Timber, brush, bridge pilings, rocks and any other structure will pop with stunning detail as you patrol the water. Take a peek; you'll like what you see.
DualBeam Plus
Get the best of both worlds, with selectable narrow and wide beams you 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. You can view the two beams separately, side by side, or blended together for the most complete picture.
Switchfire Sonar
When you hit the water, you don't limit yourself to one bait. So why limit your sonar? Exclusive Humminbird SwitchFire Sonar gives you the power to choose how returns are displayed. With two unique modes, you have complete control to adjust with the fishing conditions, making our down-looking sonar an even more valuable fishfinding tool.
