Every Bluetooth wireless enabled 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.
A little about NV: This unit has a night-vision preserving backlight which helps users to sustain natural night vision. The NV's backlight incorporates an optical filter to reduce overall brightness and minimize blue and green spectrum light to preserve night vision. Additionally, NV backlights are also much dimmer than a standard backlight, making it more difficult to detect with the naked eye in night operations. This backlight appears soft grayish pink, not red, and is still in the visible spectrum, so is not compatible with night-vision equipment.

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 ﾓbleaches outﾔ 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 ﾓbleaching outﾔ, preventing night blindness and night vision fatigue.
