The Helix 12 Series utilizes a 12.1″ widescreen that’s lit in 1500 nit brightness to display fish and structure with the amazing clarity of Full-Spectrum CHIRP technology. By broadcasting and interpreting a full sweep of frequencies from 28kHz to 540kHz (requires optional CHIRP transducer that’s not included), this powerful, finely tuned system delivers the brightest, clearest, most detailed picture possible. With AutoChart Live pre-loaded into each unit, the Helix 12 transforms unknown waters into detailed maps live, right on your screen. Mark up to 2500 waypoints onto underwater structure and contours and keep the maps you make or share them with friends with full network capabilities.

The widescreen 16:9 format allows side-by-side displays of sonar, DI, SI, or GPS screens. The internal precision GPS is complemented by LakeMaster PLUS cartography with invaluable features like 1′ contours. And the views are made even more potent by other Humminbird fish-finding technologies like Side Imaging, Down Imaging, SwitchFire Sonar, and i-Pilot Link compatibility. Dual card slots accommodate Navionics and Lakemaster map upgrades. Ethernet networking capable. 500 watts RMS.

This Helix 12 SI GPS Combo is the flagship unit of the Helix family. Its functionality includes DualBeam PLUS Sonar, GPS chartplotting with an internal GPS receiver, Down Imaging, and Side Imaging. The incredible Side Imaging Sonar combines with Down Imaging to create an amazing detailed 180° view of the water.
