Relief Shading

Easily Interpret Bottom Structure

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.

Identify Topography Quickly​

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.
