This new chart for the North Atlantic Canyons is designed to put you where the fish are. With increased depth contours, tide and current info, bathymetric coverage and more wrecks and obstructions, this chart should get you on the fish. This chart is intended for fishing, and does not offer the same level of detail as typical BlueCharts. It should be used in conjunction with the regular BlueCharts for full detail navigation information. Works with any Garmin unit that uses BlueChart.
