quadrabeam plus sonar
For a full 90º coverage, turn to Humminbird QuadraBeam PLUS™ Sonar. It uses two fan-shaped 35º side/down looking sonar beams to spot fish, bait and structure to the left and right of the boat over an area of the bottom that's always equal to twice your depth. Plus, it uses our DualBeam PLUS technology with precision 20º and wide 60º beams for a detailed view below the boat. QuadraBeam PLUS finds more fish faster, and can even tell you where to put your bait by showing if fish are to the left, right or directly beneath your boat.
