Mariner’s Eye 3D provides a bird’s eye view from above and behind 

the boat (according to your course), and provides a visual navigation 

aid. This view is helpful when navigating tricky shoals, reefs, 

bridges, or channels, and is beneficial when trying to identify entry

and exit routes in unfamiliar harbors or anchorages.

The 

key moves the view closer to your boat and lower to 

the water, while the 

 key moves the view away from the 

boat. This is indicated by the scale (

) at the bottom of the screen.
