The Kestrel Handheld Weather Meter measures
 wind and temperature with total accuracy, and has the added benefits of
 an air pressure sensor that provides altitude and barometric 
information. Kestrel technology enables you to follow changes in air 
pressure that help predict impending changes in the weather. 
There are some model that have the Olive Drab NV version which 
features a night-vision preserving backlight. This backlight 
incorporates an optical filter to reduce overall brightness and minimize
 blue and green spectrum light to preserve night vision. (Note: This 
backlight appears soft greyish pink, not "red", and is still in the 
visible spectrum, so is not compatible with night-vision equipment.)
