Garmin has introduced BlueChart g3, a line of cartography that blends together the best of Garmin and Navionics content. BlueChart g3 will also be the first preloaded cartography to offer built-in auto guidance, which instantly searches through relevant charts to create a suggested route. Chart features include navaids, spot soundings, 1-foot fishing contours, tides and currents, and detailed harbors and marinas. BlueChart g3 Vision accessory cards will also offer high-resolution satellite imagery, MarinerEye, FishEye, and high-res elevation shading to provide an easily interpreted view of bottom structure. BlueChart g3 and g3 Vision cards cost $219.99 to $449.99, depending on region.
