The Ruger 5700 Ballistics Weather Meter works with your factory Ruger rifle to give you the confidence to shoot further, in the wind, at any altitude, right out of the box. It comes with a library of pre-measured Ruger rifles and commonly available match-grade ammunition. This integrated weather meter and ballistics solver takes the guesswork out of long-range shooting and is an ideal companion for hunters, competitive, and recreational shooters working to stretch their reach in long-range shooting. The Kestrel 5 Series platform offers a large, high-resolution and contrast display with ease of font readability. It also includes a built-in dual color backlight, extra-strong polycarbonate lens, AA battery operation and LiNK iOS and Android wireless connectivity and app support. The Kestrel LiNK Ballistics app helps you build and manage your gun/bullet profiles and download them to your Kestrel Ruger 5700 before you set out. The Ruger 5700 is also a comprehensive weather meter for measurement and logging of primary environmental conditions: wind speed and direction, temperature, humidity, heat index, pressure and altitude. Like all Kestrel meters, the 5700 is drop-proof, dust-proof, waterproof and able to withstand harsh environments without damage.
