The Kestrel 4000BNV was improved to make it even more suitable for military use.

The Kestrel 4000B NV is olive drab with a visable red backlight - which helps users to sustain natural night vision. The NVs red backlight preserves the natural night vision of users such as military personnel and pilots. It takes 30 to 45 minutes for the average eye to adapt to darkness and maximize night vision. Even a short burst of white, yellow, green or blue light bleaches out the rod cell photoreceptors in the eye and causes night blindness until the entire adaptation process can take place again. Light in the red spectrum does not cause this bleaching out, preventing night blindness and night vision fatigue. This units red backlight is also much dimmer than a standard backlight, making it more difficult to detect with the naked eye in night operations.

Kestrel Bluetooth Features: Kestrel Pocket Weather Meters have specifically customized our Bluetooth integration to answer the unique needs of our customers:
Streamline your work and reduce your equipment in the field - wireless data transmission eliminates the need for a separate interface and cabling.
Every Bluetooth Kestrel will include custom communication software designed to quickly and easily configure your data transmission frequency, download logged data, graph data, and transfer data to other applications.
Data transmission range adjustment allows you to maximize power to communicate with your Kestrel at up to a 30 feet range, or reduce power for closer, more secure operation.
Individual unit IDs ensure you pair with the Kestrel you want, even when more than one system is operating in the same area.
Permanently coded unique 4-digit Pin numbers provide extra security when pairing and transmitting data
