Add Sonar with GPSMAP 740s

Add Extras with BlueChart g2 Vision
With the optional BlueChart g2 Vision SD card, you can add a whole new dimension of exceptional features to your chartplotter.
- MarinerEye view and FishEye view provide you a 3-dimensional perspective of map information, both above and below the waterline.
- High-resolution satellite images and aerial photographs help you orient yourself in unfamiliar areas.
- Auto Guidance technology searches through all relevant charts to create a route you can actually follow — one that avoids obstacles, shallow water, buoys and other obstructions.
¹Depth capacity is dependent on water salinity, bottom type and other water conditions (with 1 kW transducer).
