Kestrel Elite – Top Pick in International Sniper Competition

Kestrel® Weather & Environmental Meters, have been named as a top pick in sniper tech by FOX News at this years USASOC International Sniper Competition, held at Fort Bragg, NC, USA

During the week, the world’s elite special operations forces converge at Ft. Bragg for specialized competitions hosted by the U.S. Army Special Operations Command. The competitions are designed to challenge the real-world skills of some of the best military and law enforcement snipers and assault teams from the United States and allied partners.

The Kestrel 5700 Elite Weather Meter with Applied Ballistics was among those products used and featured throughout the weeklong competition. This compact handheld device precisely measures wind and air density while employing the cutting edge Applied Ballistics® solver to provide shooters with targeting solutions for each situation. Shooters have the option to choose G1, G7 or custom drag models to best suit their needs.

The Kestrel Elite with LiNK offers wireless connectivity to Android and iOS smartphones using Bluetooth® low energy technology, allowing for app connectivity and easy configuration and backup. Additionally, the Kestrel Elite and Sportsman models both work seamlessly with the Bushnell CONX Range Finder, receiving range data at the push of a button and transmitting the holdover value.


WEATHERFILE.COM Hits 2 Million Page Views & Mobile Friendly has made incredible advances in the last 15 months. It started life as a very flat HTML 1.0 driven website providing an incredible wealth of information. Brilliant for weather geeks with time on their hands, but not so easy to view ‘on the go’.

The team sat together and realised it was important to bring the site up-to-date. Some existing code had shown the possibility of using Google map technology to display our data. We re-visited this code and updated it using the latest version of Google API and additional code to show wind data updating live. The whole site was wrapped with Bootstrap (giving full mobile & desktop responsive feel) and we were away! As word of mouth about our new look increased, more and more users view the live WeatherFile Wind&Weather data.

In less than a year we hit our first million page views, a milestone the whole of the company was extremely proud of. We soon realised our traffic was growing at an incredible rate helped by satisfied customers spreading the word, our new Twitter account and Facebook ‘like’ posts.

Last month we were asked to provide the new BBC CountryFile Live event at Blenheim Palace with live weather data. This was streamed live from an RPR FlexiMet GSM weather station installed on site at the event and the live weather data featured on the event website front page.

Our loyal user base has loved the increase in data provided and we have quickly passed the 2 million page view mark, in under 3 months!

With new live weather sites continuing to be added, where can we get to before Christmas 2016?

North Ronaldsay now has Live Wind Data

North Ronaldsay is one of the smallest, most isolated and northerly of Orkney’s populated isles.  The island is home to fascinating wildlife, natural beauty and the island’s unique seaweed eating sheep. North Ronaldsay sheep are an ancient breed which are kept on the foreshore by a 13-mile drystone wall known as a dyke and they live mainly on seaweed. They are allowed on pasture only during lambing and are managed by a sheep court of islanders. North Ronaldsay is well known as one of the best birdwatching sites in the country during the spring and autumn migration periods. The quantity and variety of birds that can be seen at these times is often spectacular.

Man has had a profound influence on the island. The earliest evidence of human settlement was around 7000BC and it was more recently included into the Viking kingdoms of the 8th century AD.  Now home to approximately 70 people North Ronaldsay has preserved a distinct cultural tradition; loved by visitors and residents.
North Ronaldsay is now at a critical point in its history. With its population dwindling, and the islanders traditional way of life threatened, the future of the island is unclear. Tourism has become increasingly important in recent years, but still many people are unaware of this truly remote and fascinating island. Access to North Ronaldsay is by ferry or daily flights.

Knowing the local weather conditions at a destination is invaluable for pilots flying to such remote locations. North Ronaldsay airport now benefits from the addition of a FlexiMet Wind 1 System with the additional GSMWeatherfile connection. This system allows anyone with internet access via Mobile Phone, Tablet, Laptop or PC, to view, in real time, the live Wind Speed and Direction at this remote airfield.

Richard Paul Russell Ltd. have been recording live weather data for well over 15 years. Our archive provides a wealth of data events for weather historians. shows Live Wind and Weather Data from weather feeds located around the UK and Worldwide. displays Live Wind data along with data up to a 10 day period.

‘I’ll be Back’ and it is – Wind Chill !

The UK winter up to now has been wet and windy, it is now very Wet!  Noticeably though, temperature readings have been holding up above seasonal averages, but …..

This weeks weather outlook is a chilly change downwards to the more normal ‘cold’  winter temperatures. With the high winds still being forecasted, the chilling effects of the wind needs careful monitoring for the safety of all outdoor workers and those pursuing outdoor activities.

All Kestrel Weather Meters (except the Kestrel 1000) are thermo-anemometers and allow Wind Chill to be calculated and displayed.

Wind Chill becomes a hazard when heat is drawn away from the skin faster than the body can replace it. This may lead to frostbite or worse.

The chilling effect of the wind, a combination of wind speed and temperature, can be represented by the lower temperature that would be required to produce the same chilling sensation for a person walking in calm conditions. Wind Chill indicates to the user how their environment really feels and is an important indicator in assessing the comfort of personnel spending periods outdoors

The Kestrel 2000 is a small, electronic rotating vane type anemometer (wind meter) with a built-in temperature sensor. It uses high precision Zytel® bearings and a lightweight impeller for accurate air flow measurements even at low speeds. In order to quickly determine a steady temperature reading, the precision thermistor temperature sensor is mounted externally.
