The Helix 7 G3 units are equipped with an ultra wide 7" screen so that pre-selected options can be displayed in split form. MEGA Down Imaging and Dual Spectrum CHIRP Sonar are standard in the new Helix 7 G3 series. Includes GPS chart plotting and the ability to create custom charts in real time with AutoChart Live. MEGA Down Imaging is a crystal clear image to a depth of 38 meters with up to 3x more output than standard Down Imaging. Dual Spectrum CHIRP allows a choice of ‘Wide’ for maximum coverage and ‘Narrow’ for maximum detail. Thanks to the Low Q CHIRP transducer, this unit has clearly defined fish arcs, incredible target separation and fewer adjustments to settings. This fishfinder has a depth range of 360 meters.
