Best Weather Monitors of 2025

"I use the Kestrel D3FW to monitor Wet Bulb Temperature during my outdoor activities. This measurement is crucial for assessing fire danger and understanding how effective perspiration will be at different temperatures. The device works as advertised, and I appreciate the long-lasting battery when using genuine CR2032 batteries."

"For my model rocket launches, the Kestrel Data Drop units have been a game changer. With the D3FW, I can record Temperature, Humidity, and Station pressure. The Bluetooth connection to the app allows me to view and download days of data, which has completely changed my understanding of field conditions."

"I've been using the Kestrel D2 model for a few years to monitor temperature and humidity in my hatchery. Recently, I added the D3 for outdoor monitoring, and it provides pressure readings along with temperature and humidity. The data logging is excellent, but I've noticed that the iOS app performs better than the Android version."

“I find this tool to be very useful for bracket racing and have already experienced success with it. The interface is user-friendly, and I particularly appreciate the logging feature!”

“I bought this for my dad at the track, and he absolutely loves it. It performs exactly as expected and meets all his needs.”

“I've used several Kestrel weather meters, and this 5100 model is the best. It's simple to operate and offers all the information I need as a drag racer. Don't forget to get the belt case; it fits perfectly!”

“I love the high-quality materials used in this product. It feels durable and well-made.”

“Using this product is so easy. I appreciate how straightforward it is.”

“The stylish design really stands out. I get compliments all the time!”

"I've had the Kestrel 5700 for nearly two months and it's been invaluable for shooting groundhogs out to 450 yards. While I found it effective up to that range, I noticed a 1 MOA difference in some cases compared to the custom drag models. I've decided to upgrade to the Elite model to enhance my first-round hit rate."

"This device is simply fantastic. As long as you invest the time to understand it, the solutions it provides are incredibly effective. It's helped elevate my NRL22 game significantly."

"I received my Kestrel quickly from the USA, but unfortunately, it arrived defective. Thankfully, Joe Racosky at Nielsen-Kellerman provided outstanding customer service, sending out a replacement right away. I definitely recommend this unit to any serious shooter; it's a superb piece of equipment."

"I found the temperature readings to be very accurate, though I noticed that the reading was a bit slow to adjust when the wind was calm. When I took the device from my warm house into the cold, pointing the thermistor into the wind helped speed it up. I had a chance to test it at the summit of Mt. Washington and was pleased to see that the altimeter and barometer worked perfectly as we climbed to 6288 feet. It performed well even at 800 millibars and in strong winds, matching the altitude on the road signs."

"When my device arrived, it was clearly used, though it seemed to be in good shape. So far, I haven't encountered any issues. I plan to update my review later this week after I compare it with other Kestrel devices at the range."

"I appreciate how simple and customizable this device is. It shows exactly what I need, when I need it. The digital compass is incredibly precise, making it highly useful for logging data."

"I don't usually write reviews, but the high cost of the Hornady Kestrel 5700 made me feel it was necessary. This tool is well-made and designed to last outdoors. The cutting-edge technology processes environmental factors and ballistics data into a highly accurate solution. I found it very user-friendly with plenty of instructional resources available online. I'm thrilled with my purchase – it's costly, but as they say, buy once, cry once, and now I wish I had done it sooner!"

"The Kestrel is easy to use, durable, and accurate. The lithium battery lasted me nearly 8 months through weekly matches. I highly recommend this model; it's just as capable as the 5700 Elite and performs well for long-range shooting."

"I really enjoy using this meter. It offers a lot of features, and the Hornady 4DOF is fantastic. However, the Elite model is just too expensive for me right now!"

"I had the chance to test several models, and I can definitely see why the Kestrel weather meters are worth the investment. They’re very well made and the accuracy is impressive, especially with temperature changes from room to room. The ability to view three measurements on one screen is a huge plus for me. Overall, it’s a fine scientific instrument and the customer service was great too!"

"Using the Kestrel App to auto-sync data with my iPhone has been fantastic! I love how I can easily export data to CSV for my students. While I’ve only connected with one iPhone so far, the instructions suggest that multiple devices can connect at once, which is awesome."

"As someone who is learning long-range shooting, I find this device to be a solid product. It connects seamlessly with my phone and has two forms of backlights. Even without my phone, I can read the screen easily. I appreciate that it’s rugged enough to toss in my gun bag without worry. When this one wears out, I’ll definitely be purchasing another!"

"I can't believe how I ever managed without this device! It's brilliant, accurate, and easy to use! Worth every penny."

"I was struggling with wrong temperatures for my ballistic calculator. This all-in-one package has been a game changer. There are helpful tutorials online, and I should have bought this sooner!"

"The Kestrel has become an awesome addition to my shooting gear. The app works flawlessly, and I love the bright orange color—who wants a tool that blends in?"

"I don’t know how I shot long distance before I bought this. Shooting out to 1200 yards was a breeze, and it was dead on without calibration! I recommend it to everyone."

"This little meter is fantastic! Long-range shooting has become simple and fun. It's a must-have for anyone serious about precision."

"As a newcomer to long-distance shooting, this tool has gotten me on target quickly. The wind readings are spot on, and I’m amazed at its versatility!"
