2D HD Fishfinder

This unit is equipped with Humminbird Dual Beam probe technology. This provides a clearer image of the echo sounder and better detection of the seabed. The 140/240KHz probe will allow you to descend to 150m of water with a good image readable on the full sun screen.

Dual Spectrum

DUAL SPECTRUM Chirp technology is achieved with the new Chirp Humminbird probe. This wide-beam multi-frequency probe has a scanning range that works from 140 to 240khz. The latest Humminbird design office, this probe incorporates the best available ceramics, equipped with a very low "Q" factor that protects the ceramics from any unnecessary vibration. It gives you the clearest and most accurate image of the water layer. The most advanced sonar image ever available on a Humminbird sonar unit. Thanks to the 140-200khz wide beam, you no longer lose your lure and quickly locate the fish, the narrow beam that works in 180-240khz allows you to optimize the detail and the reading of the bottom. It is also possible to combine the two beams to make the most of the two frequency ranges. With these three revolutionary display modes you can effectively explore every inch of the water layer. This new DUAL SPECTRUM technology now equips all Humminbird Helix G3, G3N DS, MDI & MSI models...

Dual Spectrum

No longer miss a school of fish or an underwater structure, in a single pass the Mega Hertz definition associated with the new sweeping width displays all the details of the seabed in an ultra realistic way.

AutoChart Live

AutoChart Live

AutoChart Live software is pre-loaded with 8 hours of memory to give users the ability to create detailed bathymetric bottom mapping. This feature now allows you to display vegetation variations and bottom hardness in addition to bathymetry. The maps are created live on the screen as the prospecting progresses.

Create real-time maps of your fishing sites. Draw depth contours, bottom hardness and vegetation when driving your boat, with eight hours of built-in recording time.

To increase the memory capacity of the AutoChart Live function, the AutoChart card is required.
