Airmar is pleased to launch the OnSiteWX app which will make much of the functionality of our WeatherCaster PC software available on iPhone, iPad and iPod smart phones and tablets running iOS 6.1 and newer. By displaying data sent from an NMEA 2000 or NMEA 0183 network over a WiFi adapter connected to the network, OnSiteWX gives you easy access to data at sea or on land on your hand-held mobile device 24 hours a day. OnSiteWX is easy-to-use, customizable to your preferred settings, and allows for connectivity to many popular WiFi adapters.
