Buoys change, pool levels fluctuate, new bottom structures are found, and new contouring detail is constantly being added to our charts by using the latest technology: satellite imagery, airborne laser, sonar, plus hundreds of thousands of changes made by our community members through Community Layer. In fact, Navionics is performing an overhaul of the 1000 most popular lakes in 1 ft contours. This means new data, new boat ramps, new hot spots, new road beds, foundations, creek beds, brush piles, artificial reefs, coastlines, docks, etc.

A revolution in digital charts: not only are you empowered to edit your charts, but you also benefit from the corrections made by the entire community of Navionics users, all delivered in real time on your mobile device, and delivered daily to your plotter along with Freshest Data.
Navionics users have added Brush Piles, Fish attractors, Stumps, rocks, Fishing Spots, Wrecks, Artificial Reefs, etc. in addition to Fuel stations, Marina information and other points of interest around the lake. This is data not found on any commercial Map, is the hard to find because it is added by boaters and fishermen, and can make the difference between a tournament win and getting skunked!**
