Kestrel DROP D3 Bluetooth Ballistics Data Logger - Temperature | Humidity | Pressure
About the Kestrel DROP D3 Bluetooth Ballistics Data Logger - Temperature | Humidity | Pressure
Product Overview
The Kestrel DROP D3 Bluetooth Ballistics Data Logger is a professional-grade environmental monitoring solution designed specifically for shooters and ballistics applications. It measures and logs temperature, relative humidity, and barometric pressure—the three critical environmental factors that affect bullet trajectory and accuracy.
Frequently Asked Questions
What does the Kestrel DROP D3 measure?
The DROP D3 measures three essential environmental parameters: temperature, relative humidity, and barometric pressure. These measurements are critical for long-range shooting, ballistics calculations, and precision marksmanship.
How does the D3 help with ballistics and shooting?
The D3 provides real-time environmental data that directly affects bullet trajectory. By logging temperature, humidity, and pressure, you can make accurate ballistic corrections for long-range shots. The data integrates seamlessly with popular ballistics apps like Applied Ballistics, Strelok, and Shooter.
Which ballistics apps work with the DROP D3?
The DROP D3 is compatible with most major ballistics apps including Applied Ballistics, Strelok Pro, Shooter, Ballistic AE, and many others. The Kestrel LiNK app can share environmental data directly with these applications via Bluetooth.
How do I connect the DROP D3 to my device?
Download the free Kestrel LiNK app (iOS or Android), enable Bluetooth, and follow the in-app pairing instructions. The DROP D3 connects wirelessly up to 100 feet away and can share data with compatible ballistics apps.
What's the difference between the D2 and D3 models?
The D2 measures temperature and humidity only. The D3 adds barometric pressure measurement, making it specifically designed for ballistics applications where atmospheric pressure significantly affects bullet trajectory. If you're a shooter or need pressure data, the D3 is the right choice.
Is the DROP D3 waterproof?
Yes! The DROP D3 is fully waterproof (IP67 rated) and floats, making it perfect for outdoor shooting ranges, hunting trips, and field use in any weather conditions.
What is the measurement range and accuracy?
Temperature: -22°F to 140°F (-30°C to 60°C), ±0.9°F (±0.5°C)
Relative Humidity: 0% to 100% RH, ±2% RH
Barometric Pressure: 700 to 1100 hPa (mbar), ±1.5 hPa
All sensors are factory calibrated to professional standards.
How long does the battery last?
The DROP D3 runs on a standard CR2032 coin cell battery that typically lasts 2+ years with normal use. Battery life varies based on logging interval and Bluetooth connection frequency.
Can I mount the D3 at my shooting position?
Absolutely! The compact, lightweight design makes it easy to place the D3 at your shooting position, on a tripod, or anywhere you need accurate environmental readings. Its small size won't interfere with your setup.
How much data can it store?
The DROP D3 stores over 2,000 data points internally. When connected to the Kestrel LiNK app, data automatically uploads to the cloud for unlimited storage and historical analysis.
Can I set custom logging intervals?
Yes, you can customize logging intervals from 2 seconds to 12 hours using the Kestrel LiNK app. For shooting applications, shorter intervals capture rapid environmental changes during competition or practice sessions.
Does it work without my phone nearby?
Yes! The DROP D3 logs data independently and stores it internally. You only need your smartphone to configure settings, view real-time data, download logs, or share data with ballistics apps.
Can I set alerts for changing conditions?
Yes, the Kestrel LiNK app allows you to set custom high/low threshold alerts for temperature, humidity, and pressure. You'll receive push notifications when conditions change beyond your specified limits—helpful for tracking weather fronts or temperature swings.
Can I use multiple DROP units simultaneously?
Yes, you can monitor multiple DROP data loggers at once through the Kestrel LiNK app. This is useful for comparing conditions at different shooting positions or monitoring multiple locations.
What's included in the box?
Each DROP D3 includes the data logger unit, CR2032 battery (pre-installed), quick start guide, and access to the free Kestrel LiNK app with cloud storage.
Is there a subscription fee?
No! The Kestrel LiNK app and cloud data storage are completely free with no subscription fees or hidden costs.
Can I export my data?
Yes, the Kestrel LiNK app allows you to export data in CSV format for analysis in Excel or other software. This is perfect for tracking environmental trends at your shooting range or documenting conditions during competitions.
How does barometric pressure affect shooting?
Barometric pressure affects air density, which directly impacts bullet drag and trajectory. Lower pressure (higher altitude or weather systems) means less air resistance and higher bullet impact. The D3's pressure readings help you make precise corrections for these conditions.
Is the D3 suitable for professional use?
Absolutely! The DROP D3 meets professional standards and is used by competitive shooters, military personnel, law enforcement, and serious long-range enthusiasts who demand accurate environmental data for precision shooting.
