Humminbird Helix 7 CHIRP Mega SI GPS G4 Fish Finder – 7" Display, MEGA Side Imaging & GPS

The Helix 7 CHIRP Mega SI GPS G4 brings advanced fish-finding technology to your boat in a user-friendly package. Its bright 7-inch high-definition display offers an ample 1024x600 resolution canvas, allowing you to view multiple screens (sonar, chart, etc.) side by side without losing clarity. With MEGA Side Imaging and MEGA Down Imaging, you'll uncover the underwater world in exceptional detail – see structure, cover, and fish up to 125 feet (38 m) below and to the sides of your boat, with up to 3X more detail than conventional sonar. The Dual Spectrum CHIRP 2D sonar provides both wide and narrow beam options, so you can scan large areas quickly or zoom in on specific targets. This means well-defined fish arches and clear bottom hardness readings that make it easy to distinguish fish from the terrain.

This model includes a high-accuracy internal GPS and comes pre-loaded with Humminbird’s Basemap, enabling you to navigate confidently and mark waypoints for your favorite fishing spots or hazards. Using the AutoChart Live feature, you can create your own detailed maps in real time, recording depth contours, vegetation lines, and bottom composition as you drive your boat. This is invaluable for exploring uncharted waters or sharpening your knowledge of familiar lakes. Operating the Helix 7 CHIRP Mega SI GPS G4 is straightforward thanks to its responsive keypad controls, which are designed for reliable use even in rough conditions or with gloves. The unit's software can be upgraded, ensuring you can benefit from future enhancements and updates from Humminbird.

The package includes everything needed for installation: a transom-mount transducer, gimbal mounting bracket, power cable, and mounting hardware. The device is also compatible with optional premium charts like Humminbird LakeMaster and Navionics, should you require more detailed mapping for your adventures. Built to withstand the elements with an IPX7 waterproof housing, the Helix 7 CHIRP Mega SI GPS G4 is a robust and dependable fish finder that will elevate your fishing experience to the next level.
