Right now it seems that everything is going to 3D. The platinum is the 3D version that is only available for the ocean and great lakes types bodies of water. I purchased an E120 system a month ago. Winni is only available in a high def chart for now. Once they have it in a high def they can make it 3D according to the factory. That is why a got the E120 so that I would not get outdated in a year.
