Furuno’s NavNet system uses TimeZero technology, which allows for instant chart redraw with no lag whatsoever, even in 3D mode, and even when using radar or weather overlays. This is groundbreaking stuff, as older multifunction displays often have significant lag time, especially when interpreting large amounts of data. Traditionalists will like the 2D, top-down view, but they’ll also find it easy to think in new ways and use the 3D view. The “Roto-key” input method is user-friendly, especially once you’re familiar with the menus, pages, and command functions accessed by this knob. The interface is also helped along by the point-and-click cursor-pad control, but you can also connect a traditional mouse via the USB port. Furuno, we hear, is planning a major product release in February, and “touchscreen” is all anyone will say about it.
