See detail-rich imagery like never before

The GPS 4008 features worldwide satellite imagery to enhance the standard vector basemap format. This unit also offers the optional BlueChart® g2 Vision SD data card, which provides high-resolution aerial reference photos for help navigating tricky harbors and channels — or locating spots like area marinas, fuel stops or restaurants.
The g2 Vision plug-in data card also allows the GPSMAP 4008 to graphically depict a true 3D “mariner’s eye” topside view or “fish eye” underwater navigation perspective.

Experience super simple user interface for easy operation

With fewer buttons to push and fewer operational steps to navigate, the GPSMAP 4008’s simplified menu format makes it easy for you to see and select the data you want to access on-screen.

Simplify navigation with Auto Guidance

Optional g2 Vision auto guidance technology will help simplify your navigation. It’s like having a knowledgeable guide to local hazards and waterways always on deck. Auto Guidance searches all the chart features to suggest the best known charted route for navigation.
