Keypad control: Master HELIX at the touch of a button. Access the preloaded views from the user-friendly menu system, operated by soft key controls that allow you to reliably operate your fish finder in any conditions.
MEGA Down Imaging: Get unprecedented underwater clarity with coverage down to 125 feet below your boat. You'll unlock new details with up to 3X more fish-finding detail than standard Down Imaging sonar.
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 our proprietary, Low-Q CHIRP transducer, Dual Spectrum offers two ways to search; Wide Mode for maximum coverage and Narrow Mode for focusing on the slightest detail.
