Whether an athlete, professional coach or sporting venue the Kestrel 4400 and Kestrel 4600 are essential for measuring athletes performance and preventing heat stress. Environmental measurements such as temperature, relative humidity, heat stress index, wet bulb temperature, wet bulb globe temperature (WBGT) and more are essential to ensure safe training and competition conditions.

By using a Kestrel 4400 Heat Stress Tracker, athletes, trainers and coaches can view and record real time environmental data during practices and competition throughout the season. With 2300 storage points, users can wirelessly transfer the information captured to their PC or android phone for future reference via the Bluetooth wireless data option in the Kestrel series.

With the Kestrel 4400 users can set customisable warning screens with six individual thresholds coming as standard with the software. Each threshold can be set to signal a visual warning on the display so users can proactively monitor conditions and keep athletes safe.

Combined with the Kestrel Large Tripod and Vane Mount the Kestrel 4400 and 4600 can monitor environmental conditions remotely helping to gather valuable data before, during and after an event.

Sailing & Yacht Racing


Whether racing dinghies, keelboats or cruising in blue water, The Kestrel range of weather meters can supplement land based or on board weather information. Understanding the exact wind speed, average wind speed and maximum gusts gives the exact data required to ensure the perfect rig set up and maximise the crafts performance.

The Kestrel 1000 is an extremely cost effective entry level model supplying average wind speed, current wind speed and maximum gust.

The Kestrel 5000 monitors a far wider set of weather parameters including barometric pressure, pressure trend, relative humidity, heat stress index, wind chill and many more. When combined with automatic data storage, this is useful when reviewing rig performance, tracking storm development and deciding future rig settings and clothing requirements. 100% waterproof and durable the Kestrel floats in water minimising the likelihood of loss.

Skiing & Snowboarding


Competition skiers, mountain rescue teams, snowmaking personnel, ski patrols and resort managers all require accurate, instant and local weather information. From a competitors decision about what equipment and wax to use, to resort managers determining when and where to use snowmaking equipment.

The Kestrel 5000 and Kestrel 3500 feature an external temperature sensor. Simply place the sensor into the snow pack to gain fast and accurate data wherever you are on the piste. The added functionality of wind speed, wet bulb temperature, relative humidity, wind chill, and barometric pressure provides full weather station data in your hand from anywhere on the resort. Tough, durable and waterproof it will also last.

Hang Gliding, Paragliding & Ballooning


Powered and unpowered aviation enthusiasts are heavily reliant and influenced by the wind. The Kestrel 1000 delivers extremely accurate current wind speed, average wind speed and maximum gust speed data in your hand from the exact launch location.

The Kestrel 2500 includes altitude, pressure and wind chill data all important when determining flight pattern and clothing requirements.

The Kestrel 4500 increases functionality further by supplying wind direction, crosswind and headwind/tailwind calculations accurately and automatically - valuable data prior to launch. Kestrels start from under £100 come with a 5 year warranty, are extremely waterproof and durable making it an essential piece of kit for all air sports enthusiasts.

Backpacking, Camping, Climbing & Mountaineering


Monitoring and predicting weather in remote areas can be challenging, understanding current and future weather conditions is vital for good preparation and the ongoing safety of any outdoor activity. Carrying a Kestrel Pocket Weather Meter gives the valuable environmental parameters required to make key decisions such as; do I push for the summit, what clothing to take, how large is the weather window, what level of heat stress will I endure.

The Kestrel 5000 delivers all the parameters required including barometric pressure, pressure trend, altitude, relative humidity, heat stress index, dew point, wet bulb temperature, density altitude, wind chill, temperature (air, water and snow), current wind speed, average wind speed, and maximum gust. The Kestrel 5000 has an extensive memory and can log data to be reviewed at PC, sent to base camp or rescue teams. Whatever level your outdoor activity Kestrel will ensure you start fully prepared.

Search & Rescue

Search & Rescue

Rescue teams need to quickly and accurately assess the conditions wherever they're working, they need to monitor the local weather conditions, predicted weather conditions and information to assess exposure and heat stress. This information is vital for ground crews and rescue helicopters to deliver fast and save evacuations.

The Kestrel 5000 supplies valuable data including barometric pressure, pressure trend, altitude, relative humidity, heat stress index, dew point, wet bulb temperature, density altitude, wind chill, temperature (air, water and snow), current wind speed, average wind speed, and maximum gust. This data provides the foundation for fast and decisive decision making ensuring the safety and speed of all those involved in a rescue operation.

Kite Surfing & Windsurfing

Kite boarding

Up to the second accurate wind speed information is what the windsurfer and kitesurfer need to determine sail area and board choice. The Kestrel 1000 for under £100 delivers current wind speed, average wind speed and maximum gust in your hand providing wind information pin point accurate to your location.

The Kestrel 2000 includes temperature (air and water) and wind chill helpful when considering the correct attire and how the conditions will feel on the body. 100% waterproof, held in a durable casing with a patented replaceable impellor the Kestrel won't let you down however hard you play.

Paddling & Kayaking


Paddling and kayaking enthusiasts are keen to understand wind speed and water temperature. Long distance touring paddlers use this information to decide upon their equipment list, clothing and likely distance to be travelled. The ability to predict changing weather makes long distance trips safer and more enjoyable. The white-water paddler will utilise the water temperature and wind chill information when calculating the amount of clothing required and potential impact on their performance.

The superlight Kestrel 2000 displays current wind speed, average wind speed and maximum gust with air/water temperature and wind chill.

The Kestrel 3500 carries the extra functionality required to predict future weather conditions, monitor relative humidity and heat stress. Both models are fully waterproof, lightweight and durable.



Flying enthusiasts whether private plane, small helicopter, ultralight or glider rely upon accurate weather information when taking off or landing. The Kestrel 5000 delivers key information including wind speed, altitude, barometric pressure and density altitude readings particularly useful when flying to remote or unmanned locations. Each Kestrel is designed with a huge amount of market knowledge and expertise and with one of the Kestrel founders being an avid glider pilot. The Kestrel has unique functionality tailored to flyers' exact needs.
