  • CHIRP Digital Sonar
    • CHIRP stands for "Compressed High-Intensity Radar Pulse." By covering a wide range of frequencies, CHIRP produces more accurate, more detailed returns of fish, structure, and the bottom.
  • Dual-Spectrum CHIRP Sonar
    • Before you cast, know what's down there thanks to highly detailed fish arches and a clear view of fish-holding structure and the bottom. Powered by Humminbird's proprietary Low-Q CHIRP transducer, Dual Spectrum CHIRP 2D sonar offers two ways to search: Wide Mode for maximum coverage and Narrow Mode for focusing on the slightest detail.
  • Precision GPS
    • Precision GPS provides an accurate position fix, meaning more accurate waypoints and boat positioning for better fishing.
