The Kestrel 4000 Pocket Weather Tracker is Kestrel's flagship meter. Capable of monitoring and reporting an exhaustive list of environmental parameters fast and accurately – from temperature to barometric pressure, Heat Stress, Current / Maximum / Average Wind Speed/Direction, Wind Chill,Heat index,Wet bulb, Dewpoint, Relative Humidity and Altitude.
These added features make the 4000 the Kestrel Meter of choice for military professionals and flight crews. Like all the pocket weather meters in the Kestrel range the 4000 series is capable of storing and charting up to 2000 point data logger.
For military professionals, the NV version of the Kestrel 4000 features a filtered back-light to reduce overall brightness and minimize blue and green spectrum light to preserve night vision. (Note: This back-light appears soft greyish pink, not "red", and is still in the visible spectrum, so is not compatible with night-vision equipment.) The NV light is designed for optimal performance in low-light conditions. Weekend shooters and military snipers alike have been calling for a Kestrel Meter with crosswind calculation for years — and the Kestrel 4000 meets that demand completely.
