WeatherFile (PRO) Principal Race Officer System

Android & iOS Compatible The PRO system combines a state-of-the-art Gill MaxiMet GMX200 (GPS) sensor delivering extremely accurate wind speed and direction measurements, with a built-in compass automatically calculating north even if the committee boat is swinging under anchor.

Data transfers over WiFi to a tablet or smartphone within 20 metres. The data display delivers live wind speed and direction data every 10th second shown as a compass rose in degrees. In addition, rolling averages are shown in graph format and updated every 2 seconds, the rolling average interval can be set at either 1, 3 or 5 minute periods and shows the last 2 hours of data.

Additionally, data is sent via GSM mobile connection (3G/4G) to the website enabling viewing by any internet connected device from any location. For post-race analysis and graphing, data can be downloaded in .CSV (Excel) format.

The unit comes complete with a foam padded, waterproof and durable IP67 rated carry case, mast, jubilee clips and 3 methods of power attachment; crocodile clip, cigarette lighter and mains adaptor plug enabling quick setup and attachment to the committee boats (12Vdc) battery or any other 12Vdc battery source.
