Welcome to the pinnacle of fishfinders. The Humminbird® HELIX® 12 Mega SI G2N GPS Fishfinder and Chartplotter represents the best fishfinder ever designed, and the cutting edge of fishfinding technology and innovation. Its brilliant 12.1" screen with 1,500-nit brightness allows easy viewing even indirect sunlight. Patented Humminbird Side Imaging® range now extends to a full 400' either side of the boat for 800' of side-to-side coverage, revealing even more key structures and fish. Powerful CHIRP SONAR allows the unique selection of Low, Medium, and High frequency ranges, giving clean returns and exceptional target separation. Down Imaging® brings crystal-clear returns to depths of 250', and SwitchFire® SONAR with depths of 600' shows intricate details of bottom and structures. Side-by-side presentation of Down Imaging and SwitchFire SONAR delivers ideal vertical viewing for fishing, actively showing your lure and fish for perfect preparation.
