The Kestrel 5000 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. Like all Kestrel meters, the Kestrel 5700 is drop-tested, dust-proof, waterproof and able to withstand harsh environments without damage– so it can accompany you to the range or hunt for years to come. A range of carry pouch options makes it even easier to take your Kestrel 5700 with you.
