The Humminbird Helix 7 CHIRP G2 is the second generation of Humminbird Helix fishfinders/chartplotters and employs multi-frequency CHIRP technology for better target separation, deep water penetration, and decreased water column clutter. The head unit features a brilliant 7″ diagonal 16-bit grayscale color TFT display with 800H x 480V pixel resolution that provides crystal-clear viewing in harsh sunlight and works perfectly for split-screen imaging. Selectable color palettes that represent the relative strength of returned sonar signals optimize the identification of bottom structure, hard and soft bottoms, and fish targets. The available sonar options for the Humminbird Helix series include sonar only (first generation), and down-imaging and side-imaging CHIRP as second generation sonar technologies, including G2N networking enhanced data sharing through Ethernet.
Dual Beam
The Helix 7 Sonar units offer the first generation DualBeam PLUS Sonar and SwitchFire Sonar features. In DualBeam PLUS, the two frequencies available are the traditional 200kHZ for shallower depths less than 800 feet
