Detailed Nautical Charts Wherever You Will Go
The Boating App provides nautical charts for cruising, fishing, sailing, diving and all the other activities on the water.

Satellite Overlays with SonarChart Shading
SonarChart Shading gives a detailed rendering of the seafloor and lake bottoms in varyng shades of blue and provides you with a greater awareness of the surrounding environment. This visual data, created from HD SonarChart data, can help you identify the areas richest in fish.
Relief Shading
For coastal and inland boat owners who need to know as much as possible about depths and bottom structure maps, 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.
