    The 4500NV is the one for that.

    The Kestrel 4500 NV with Horus ATrag Ballistics combines Kestrel's flagship meter, the Kestrel 4500 with Night Vision, with Horus ATrag Ballistics software to bring you the first lightweight, hand-held tool to give you both comprehensive environmental data plus integrated aiming solutions. Kestrel Pocket Weather Meters and Horus Vision partnered to provide a powerful shooting tool that combines the critical environmental data and targeting software solutions required for precision shooting.

    The Kestrel 4500 NV with Horus ATrag Ballistics allows you to load, customize and store multiple guns, rounds and targets. Target parameters include distance, angle, longitude, speed, direction and wind. Kestrel's highly accurate measuring and averaging of wind together with built-in digital compass for target bearing and wind direction assists in defining the target winds. The Kestrel 4500 NV with Horus ATrag Ballistics is available with Bluetooth technology, which allows you to communicate with your Kestrel wirelessly at a range of up to 30-feet, and maximize the battery life of your meter. Note: The Horus Ballistics support G1 ballistic coefficients only.

The unit displays ballistic tables with data of the shot extending out to various distances (see Range Card on page 17 and 18 in the manual). This Horus meter can provide ballistics solutions out to 4000 yards (or about 3700 meters).
