The Kestrel 3500 provides comprehensive environmental measurements with the simplicity of the Kestrel 1000. The Kestrel 3500 scrolls through the current readings of nine different weather variables, packing quite a punch into a package that weighs about two ounces!

The Delta T version (Kestrel 3500 DT) offers a quick guide to determining acceptable spraying conditions for agricultural interests. This unit incorporates barometric pressure correction in its wet bulb temperature calculation, ensuring accuracy even on low pressure days, at high altitudes, and in the very dry weather when Delta T monitoring is important. The 3500DT does NOT provide wind chill and heat stress index

Much dimmer than a standard backlight, the night vision version of this model (Kestrel 3500 NV) has a night-vision preserving backlight, which helps to maintain the user's natural night vision.

4 stars Kestrel 3500
Small, lightweight, easy to read. Baro and Alt require calibration before 1st use. All features within spec except Humidity. Not sure yet if this is due to local variation or electronic error. Still testing. On the whole I like it very much and it goes with me on every hike.

5 stars Kestrel 3500NV Pocket Weather Meter
As a geologist I used Kestrel wind instruments years ago. This product adds other relevant weather information useful during outdoor activities. The instrument is accurate, durable and easy to use.

2 stars Concerned with device
the rotor on the Kestrel 3500 that I received is not balanced. I would like to return it for a device that is balanced. at low air speed, it must be encouraged to rotate by blowing on it. not what I expected from a high quality device.
