Kestrel 4500 Pocket Weather Tracker

overview
for years our customers have been asking for wind direction along with wind speed. new for 2007, the kestrel 4500 does just that with its built in digital compass. but it doesn’t stop there. it also calculates crosswind and headwindtailwind with reference to a user-set target heading, and stores the information along with all the other environmental readings in its 1400 data point memory.
pair the 4500 wind meter with the kestrel vane mount and you have a data-logging weather station that sets up in seconds and rotates in the slightest of breezes. did we mention that the whole kit is the ultimate in portability? it packs down into a 2 x 6 inch pouch and weighs under 8 ounces.
available in the nv configuration
military personnel and pilots flying in darkness are often concerned with preserving their night vision. due to overwhelming demand from our military customers, the kestrel nv line was added in 2005.
the kestrel 4500nv is available with an olive drab case or a desert tan case. the 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 greyish pink, not red, and is still in the visible spectrum, so is not compatible with night-vision equipment.
