Conditions on the track can often vary greatly from those in the pits. The rugged, portable and easy to use Nielsen Kellerman Kestrel 4250 Racing Weather Tracker quickly provides racers and pit crews with the most accurate and up-to-date data available where you need it most — at the track. It allows tuners to determine what last minute changes need to be made based on the current local conditions, even immediately before the first lap around the track or pass down the drag strip — giving you that competitive edge at a fraction of the cost of other systems on the market.

Knowing the current environmental conditions can often be the difference between finishing in the money and just finishing. Even slight changes in air density, water grains, and density altitude can dramatically affect a machine’s performance. With the added ability to easily measure and track these and other critical factors, such as absolute pressure, temperature, humidity, wind speed and barometric pressure, the Nielsen Kellerman Kestrel 4250 Racing Weather Tracker arms racers with the accurate weather data needed to make those last minute jetting or tuning decisions.

The Nielsen Kellerman Kestrel 4250 Racing Weather Tracker also features an automatic and manual data storage function, allowing you to easily keep logs of race day conditions from track to track, year to year. The Kestrel PC Interface and Communicator Software allows data to be easily transferred directly to a PC or laptop making long-term storage, in-depth analysis, and detailed charting of stored data a breeze.

Both real-time and logged data can be transferred wirelessly and automatically to a laptop or PDA, making the Kestrel 4250 Racing Weather Tracker with Bluetooth the perfect tool for virtually any job that requires quick and reliable weather data. The Bluetooth version of the Kestrel 4250 includes custom communication software designed to quickly and easily configure your data transmission frequency, download logged data, graph data, and transfer data to other applications. Data transmission range adjustment allows you to maximize power to communicate with your Kestrel 4250 Racing Weather Tracker at up to a 30 feet range, or reduce power for closer, more secure operation. Individual unit ID’s ensure you pair with the Kestrel 4250 you want, even when more than one system is operating in the same area. And, permanently coded unique 4-digit Pin numbers provide extra security when pairing and transmitting data.
