New versions of my GPS Anti Spoof app are now available (android and iPhone/iPad). While most navigators will never encounter any significant satellite spoofing, the app also serves as a great sextant education, sextant practice, and sextant testing tool. Shoot your sight and compare (with a built-in time delay if you're working alone). That's all there is to it. You get instant feedback on your sights. The app does not normally require internet access and will work on the open ocean.
Note: This is an important "maintenance update". If you already have the app, standard or pro version installed, the update will be delivered to your device automatically in the next few days.
