GARMIN G3 VISION - REG - VSA002R-South America West Coast BlueChart g3 is a more economical option for our value-end chartplotters. It has safety depth settings to let you select up to 5 values for specific depth contour intervals. And the fishing charts emphasize bathymetric contours with less visual clutter on the display. There's also a choice of standard 2-D direct overhead or 3-D “over the bow” map perspective views to make chart reading and orientation easier. |
