Kestrel 5700 Ballistics Weather Meter with LiNK Overview

The next generation of ballistics weather meter is here with the Kestrel 5700 Ballistics Weather Meter.

The Kestrel 5700 is a tremendous value in full-featured ballistics calculators. Providing the same trusted accuracy, reliability, and usability as the original Kestrel 5700 Elite Ballistics Weather Meter, 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 optional LiNK iOS and Android wireless connectivity and app support. Like all Kestrel meters, the Kestrel 5700 is drop-proof, 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.

Buy the Kestrel 5700 with LiNK and get the power of the Kestrel LiNK Ballistics app for Android or the Kestrel Link Ballistics app for iOS for free. Build and manage your gun/bullet profiles and download them to your Kestrel 5700 before you set out. At the range or match, secure your Kestrel 5700 to a tripod using the optional Kestrel Vane Mount and use the app to quickly adjust the target range and view the shooting solution and wind rose without leaving your shooting position. It’s like having a meteorologist and ballistician standing next to you while you shoot.

In addition to the ballistics solver capabilities, the Kestrel 5700 is a comprehensive weather meter for measurement and logging of primary environmental conditions: wind speed and direction, temperature, humidity, heat index, pressure and altitude. Paired with the Vane Mount, the Kestrel 5700 Ballistics Weather Meter becomes a compact, easily-deployable weather station. Your data log can be transferred to a iOS/Android device wirelessly with the LiNK wireless communication option and Kestrel LiNK app, or to a Windows/Mac device with either the accessory Kestrel LiNK Dongle or waterproof USB Data Transfer Cable (Both sold separately).

Kestrels have been put to the test in some of the harshest conditions on the planet. U.S. Special Forces, combat weather teams, wildland firefighters, smoke jumpers, Mt. Everest expeditions and auto pit crews are just a few who rely on a Kestrel to provide them with the crucial environmental data they need. Watch any on-screen meteorologist during a hurricane, and you’re sure to spot a Kestrel in action. With a Kestrel 5700, you can put accurate shooting solutions and environmental measurements in the palm of your hand, anywhere your adventure takes you.

Calibration drift < 1% after 100 hours use at 16 MPH|7 m/s. Replacement impeller (NK PN-0801) field installs without tools (US Patent 5,783,753). Wind speed calibration and testing should be done with triangle on impeller located at the top front face of the Kestrel. Measuring wind speeds above 60 m/s / 134.2 mph can damage the impeller.

Airflow of 2.2 mph|1 m/s or greater provides fastest response and reduction of insolation effect. For greatest accuracy, avoid direct sunlight on the temperature sensor and prolonged sunlight exposure to the unit in low airflow conditions. Calibration drift is negligible for the life of the product. For further details, see Display & Battery Operational Temperature Limits.
Relative Humidity 2%RH 0.1 %RH 10 to 90% 25°C noncondensing To achieve stated accuracy, unit must be permitted to equilibrate to external temperature when exposed to large, rapid temperature changes and be kept out of direct sunlight. Calibration drift is typically less than ±0.25% per year.

Monolithic silicon piezo-resistive pressure sensor with second-order temperature correction. Between 1100–1600 mbar, unit will operate with reduced accuracy. Sensor may not operate above 1600 mbar and can be damaged above 6,000 mbar or below 10 mbar. Calibration drift is negligible for the life of the product.
1/16th Cardinal Scale
0 to 360° 2-axis solid-state magneto-resistive sensor mounted perpendicular to unit plane. Accuracy of sensor dependent upon unit’s vertical position. Self-calibration routine eliminates magnetic error from batteries or unit and must be run after every full power- down (battery removal or change). Readout indicates direction to which the back of the unit is pointed when held in a vertical orientation. Declination/variation adjustable for True North readout.
