Details & Specs

There's no such thing as a new body of water when you have a Humminbird HELIX® 7 CHIRP SI GPS G2 Sonar Fish Finder. When you arrive at that sweet spot, SwitchFireTM Sonar will add a new dimension to what you see beneath the boat with two unique display modes that you can adjust to current fishing conditions. Use the AutoChart® Live software to create a detailed map that includes depth contours, bottom hardness and vegetation in real-time and can be seen with impressive clarity even in harsh light conditions on a brilliant 7" diagonal color display with LED backlighting.

  • Side Imaging® will give you a 180° side to side view from beneath the water with high-frequency beams to reveal images with crystal clarity even in murky water
  • Down Imaging® lets you get a fish-eye view of what's happening from below your boat and see fish, structure or rocks with stunning detail
