  • HELIX 7- MEGA Side Imaging: See the world below like never before with crystal-clear viewing out to 125 feet on either side of your boat. You'll unlock new details with up to 3X more output than standard Side Imaging sonar.
  • HELIX 7- 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 output than standard Down Imaging sonar.
