The innovative Helix uses high-frequency beams to vividly reveal structure, cover, and contour changes below the water’s surface. DualBeam PLUS technology utilizes both a narrow beam and a wide beam to provide outstanding detail and a wide coverage area. Side Imaging offers a 180-degree, side-to-side view using an ultra-thin beam that scans areas up to 240 feet on the left and right for a total coverage area of 480 feet! Down Imaging captures a fish-eye’s view of surroundings below your boat. In addition to a GPS receiver with Tracking and Chartplotting, each Helix also features built-in ContourXD base map cartography that covers 3,000 U.S. lakes with depth contours and many other locations without contours. Other features include a backlit color LED display, 16:9 widescreen format that allows you to view cartography and sonar imagery side-by-side, and dual SD card slots.
