The Kestrel 3500 Weather Meter has all the capabilities of the Kestrel 3000, plus:         

• Barometric Pressure
• Barometric Trend
• Altitude
• Clock

In addition to the Kestrel 3500's pressure trend indicator, it also has the advantage of altitude and barometric pressure measurement. With these features on hand at any time, the Kestrel 3500 becomes an ideal weather instrument for outdoor enthusiasts, sportsmen and women, and anyone else that will benefit from accurate and up to the second weather and barometric information.

The Barometric Trend feature is not quite the graph of the Kestrel 4000 series, but rather an arrow indicator.  The arrow will indicate the trend of the previous 3 hours even if the meter was off.  If the batteries are changed, the arrow will show just the current trend, not historical.  

For military, or just those using it at night a lot, the Olive Drab NV version of the Kestrel 3500 features a night-vision preserving backlight. Backlight incorporates 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.)

The Kestrel 3500's easy to use menu system scrolls through 9 different environmental measurement conditions. It has an external temperature sensor with a waterproof casing that allows you to gauge the temperature of water, snow, and the open air. The sensitive and user-replaceable impeller technology provides accurate wind speed info, and a hard slide-on case, lanyard, and battery are included.
