TZ Professional is the advanced edition of the TimeZero marine navigation program from the Nobeltec company. The application was designed for professional fishermen and workboats and gives you access to a wide variety of navigation options, helpful route planning features, weather forecasts, and so much more.

Before using the application on your Windows PC, check your email for a message from the developer that will help you download necessary navigation chart data. Each TZ Professional license you purchase comes with a pack of chart data which can be installed directly from the app's interface. Simply copy the downloaded ZIP files in the My Document -> My TIMEZERO -> Downloaded Charts folder, launch the program, and it will start installing the chart data.

Besides providing you with features which can also be found in the standard version of the app (plan routes, check weather forecasts, etc.), this program also gives you access to specific tools and buttons that are useful while fishing, extra boat track options, and much more.

The new security cone feature might also prove to be of good use while sailing. It detects isolated dangers and shallow areas and an anti-grounding alarm is immediately triggered if an obstacle is being identified within the selected cone.

All in all, TZ Professional proves to be a reliable solution for professional fishermen and workboats as it provides you with plenty of useful features, great performance, and a user-friendly interface.
