Wareham, Mass. – Millions of mobile device owners have downloaded Navionics apps and would never think of going fishing or boating without their charts. Very soon they will be able to enjoy a great new feature directly from their iPhone or iPad.

Navionics and Vexilar are cooperating to integrate Navionics Boating, the top-ranking app from Navionics, with the Vexilar SonarPhone which will allow boaters to see their sonar and Navionics charts, both full screen and split screen, within the same app.

“For the first time ever, you will be able to utilize split screen view of charts and sonar display to monitor water depths and watch your position on the charts. The Navionics Boating app with integrated SonarPhone functionality is simply a natural evolution of smart technology.” said Steve Baumann, owner of Vexilar. “Vexilar pioneered many of the sonar technologies fishermen have been using for last 55 years, from our introduction of the first LCD sonar to our dominance in flasher sonar technologies for ice fishing. Our breakthrough with SonarPhone Wi-Fi technology is definitively where the future of fish finding technologies will be in just a few years. Navionics Boating and SonarPhone make for a robust and powerful team.”

And what’s more, boaters will be able to save and send their sonar logs to Navionics and see a new chart, updated with these data, after about a week. For Navionics, this is a great advancement for SonarCharts™, the HD bathymetry map users can enhance, that can be seen on plotter, mobile and even web. Any updated SonarCharts™ resulting from individual contributions are visible by the whole Navionics Community on any compatible device.

“As we embrace wireless technology, our partnership with Vexilar creates a wow factor by connecting sonar with charts on handheld devices like iPhones and iPads at a very low cost.” commented Don Black, Senior Vice President of global sales and marketing, Navionics. “We are offering more and more ways to provide the greatest benefit for all so that any user can improve charts anywhere they want more detail, anytime they choose.”

Availability Any Navionics Boating, Marine, or Marine & Lakes app currently on the market can be updated with SonarPhone functionality, scheduled for mid-August release on the iTunes App Store for use on iPhone and iPad. This enables the app to display data received from a SonarPhone T-BOX WiFi transmitter, which is a device that must be purchased separately. Navionics app users who purchase a Navionics+ subscription for detailed Navionics charts, offered within the app from many worldwide regions, also have access to the improved SonarCharts™. SonarPhone update for Navionics apps on Android will be released at a later date.
