New Navionics Sonarcharts Available!

Recommended Posts

Hey all, I've been seeing some awesome new SonarCharts popping out while I'm traveling to different lakes across the country.

For those that aren't yet up to speed, Navionics SonarCharts are a compilation of sonar logs from the Navionics Community making for some of the freshest and most accurate lake maps available. There are literally thousands of logs being updated and the more logs that are submitted of a single body of water, the more the data evolves and stays up with the changes created from environment. It's fine tuning our maps as we know them.

Recently I was at Lake Amistad and used the newest SonarCharts to help me find bass holding structure that wasn't near as pressured as ones that were more easily found. I also was able to locate isolated humps that are often missed by survey crews who log sonar in the most economical way possible to be more profitable.

Here's a few screenshots from the Navionics WebApp. The first two show the traditional HotMaps layer compared to the new SonarChart layer. Notice the added detail and how the humps have evolved over time. The second set of screenshots show how SonarCharts can be used to map lakes or creeks in this case that haven't yet been surveyed.
