Relief shading delivers highly detailed shading that combines color and shadow to provide an easy-to-interpret, clearer view of bottom structure than contour lines alone.
For coastal and inland boat owners who need to know as much as possible about sea and lakes beds, relief shading offers a better understanding of bottom detail for improved fishing and diving.
We use the best data available from our sources.
In some cases, high-resolution data is mixed with low-resolution data to produce a more complete image. The most convenient way to preview relief shading in your area of interest is on the Navionics Boating app.
Included as a downloadable option with Platinum cards, it can be viewed with compatible models from many brands.
