The
Kestrel Night Vision models offer the same features as the regular
kestrels but with an olive drab case with a visible red backlight
- which helps users to sustain natural night vision. The NV’s
red backlight preserves the natural night vision of users such as
military personnel and pilots. This unit’s red backlight is
also much dimmer than a standard backlight, making it more difficult
to detect with the naked eye in night operations. The Night Vision
model is only available for the 2500, 3500 & 4000. |
Measurments
The Kestrel 1000 - 4000 models do not measure wind direction, please see the Silva Polaris Compass if interested in measuring wind direction. The Kestrel Tactical sheath sold for the Kestrels fits the compass and a Kestrel Weather Meter. |

Temperature Limitations: Kestrel 1000, 2000, 3000, 2500, 3500 : Operation from -15oC to 50oC [5oF to 122oF]. Below -15oC [5oF] the display fluid will freeze. Above 50oC, the display will turn black. This is temporary and the display will function properly when unit is returned to normal temperature Accurate readings may be taken by keeping the unit warmer than -15oC [5oF], or cooler than 50oC [122oF], and exposing it for the minimum time necessary to take a reading (less than one minute). Kestrel 4000: Operation from -20oC to 60oC [-4oF to 140oF]. Below -20oC [-4oF], accurate readings may be taken by keeping the unit warmer than -20oC [-4oF] and exposing it for the minimum time necessary to take a reading (less than one minute).
