Transfer. Unit is supplied with 2 AAA batteries, a soft carry pouch,
impeller cover, instructions and a Certificate of Conformity. Integrated
Bluetooth® wireless technology option available, both real-time and
logged data can be transferred wirelessly and automatically to a laptop
or PDA. 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 “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.
