Why Humminbird HELIX 5 CHIRP GPS G3?

The HELIX 5 is the step up from the Garmin Striker for anglers who want a real chartplotter alongside their sonar — the built-in GPS with AutoChart Live lets you build custom bottom contour maps of any lake you fish. If you're returning to the same bodies of water across your RV travels, this unit turns those lakes into mapped fishing grounds over time. Humminbird's CHIRP sonar quality is class-leading.
