The Kestrel® 4000NV units are olive drab with a visible red backlight, which helps sustain the user's natural night vision. Military personnel and pilots flying in darkness are often concerned with preserving their night vision. 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. The units' red backlight is also much dimmer than a standard backlight, making it more difficult to detect with the naked eye in night operations. "Night-vision preserving backlight. Backlight incorporates optical filter to reduce overall brightness and minimize blue and green spectrum light to preserve night vision.  (Note:  This backlight appears soft greyish pink, not "red", and is still in the visible spectrum, so is not compatible with night-vision equipment.)"  The chart mode allows users to recall and graph up to 2000 measurements, along with the date and time of storage. Barometric Pressure Altitude  Density Altitude  Temperature  Humidity  Wind Speed  Wind Chill  Dew Point  Wet Bulb Heat Index..  All in one pocket sized instrument. Does not show red background in picture. Clamp any Kestrel into this sturdy but lightweight tripod to take readings in the field. The tripod’s legs extend to permit a maximum height of 10", and a minimum of 6". Ultra-compact and portable, it folds to just 7.5” and weighs 4.8 oz. For further options, the top clamp detaches and is compatible with any tripod with a standard tripod mount. Comes with a padded carry pouch. The Kestrel Portable Vane Mount is an ingeniously simple accessory designed for extreme light weight and portability. The Vane Mount assembles in seconds and the precision pivot and lightweight vane extension allows the unit to spin freely in the slightest of breezes. The incorporated level ensures that the Vane Mount is installed correctly and that direction readings will be accurate. Paired with the Kestrel's 2000 data-point memory log, extensive data can be collected including wind speed and direction. Together, the Kestrel 4000NV and Vane Mount weigh less than 8 ounces (227 g.) and pack into a compact 2 x 6 inch (5 x 15.25 cm) case. The Vane Mount can be affixed to any tripod for a complete weather station you can easily pack into remote locations.  The unit comes with a case to transport the vane together so pieces are not lost. This compass has 2° graduation lines as well as large numerals at every 20° mark, and its clear base plate makes it easy to read a map and set bearings. To get a precise wind direction, simply point the large base plate arrow into the wind, turn the bezel to match the red North indicator to the red needle, and read the wind direction at the base plate arrow. This full-featured compass has a declination correction scale to allow you to make quick adjustments of map bearings to field headings, a sure-grip dial and ergonomically-contoured base plate, includes inch and millimeter rules for mapping and plotting. I prefer PayPal, but will take money orders, bank checks, or personal checks (orders held for 10 days to allow personal checks to clear).  I leave feedback as soon as payment is made, and attempt to ship ASAP with all orders.
