Kestrel 4500NV WT Horus® Ballistics Bluetooth®

Kestrel Pocket Weather Meters and Horus® Vision have partnered to provide a powerful shooting tool that combines the critical environmental data and targeting software solutions required for precision shooting -- all in one four-ounce pocket-sized unit. Previously, shooters would need to obtain environmental data from a Kestrel meter and then input that data into a PDA loaded with Horus® ballistics software. Now, the Kestrel Ballistics Weather Tracker™ with Horus® Software contains all of the necessary data and solutions in one device to minimize user workload and distraction. Plus, the Kestrel meter is IP67 waterproof and MIL-STD-810F rugged, allowing users to avoid the expense and weight of a ruggedized PDA.

The new unit allows users to load and customize multiple guns and rounds from the extensive proprietary Horus® database. Simple, intuitive screens allow the user to create up to five targets customized for location, distance, direction, declination and winds. The Kestrel meter's highly accurate measuring and averaging of wind and digital compass for target bearing and wind direction assists in defining the target winds. Once these parameters are set, the Kestrel meter takes over - tracking the current met data and automatically updating the firing solution using Horus® advanced proprietary algorithms and taking coriolis and spin drift into account. No additional user input is required.

Note: 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 greyish 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.
