New Humminbird® AutoChart™ uses proprietary software that takes your Humminbird’s sonar recordings and GPS to build custom lake charts.
Create your own contour map on any lake in 3 simple steps:
- Record sonar data after inserting a blank SD card into your Humminbird Combo.
- Import your recordings into the AutoChart PC program and convert your survey into a lake map.
- Export your map onto the Zero Lines Map Card (included) to display on any compatible* Humminbird.
