Comparison of the Swiss Skywatch windmeters

Skywatch is back on our shelves. In this article, we would like to present and introduce you to the individual models of these sensational anemometers from Switzerland.

In our offer you will find standard models that display the measurement on the built-in display and those that you can connect to your smartphone. What are the differences between them, which model will meet your requirements? This article should dispel all your doubts.  
The first question we should ask ourselves when choosing our new Skywatch is: "Do I want to check the weather information directly on the measuring instrument or display the measurement in real time when my phone connects to Skywatch® BL via Bluetooth?". Here we distinguish two categories of wind meters: manual and smartphone weather station.  
We will first present you with the features of handheld wind meters. 
 
Handheld windmeters  
The handheld wind meters we have on our offer include the following models: Skywatch®Xplorer, Skywatch® Eole, Skywatch® Meteos, Skywatch® Atmos, with the Xplorer available in 4 versions. What is the difference between the different models, what are their functions and specifications - you will find out soon.  
Skywatch® Xplorer.  
 
According to manufacturer's website "As a pioneer in the field of manual anemometers, JDC Electronic has been focusing its efforts on the development of high quality anemometers for over 20 years with its Skywatch brand aiming to make the most perfect match of simplicity and efficiency"  
Xplorer wind meters are simple in their design, but with high quality components, they will meet the expectations of even the most demanding users. Depending on the model, we have manydifferent functions at our disposal: wind, temperature, pressure, height and even a compass reading in degrees.

We probably already know everything about the Xplorer model, so let's have a look now at other handheld windmeters which are equipped with a large 54-millimetre propeller, so they don't need to be positioned precisely against the wind, i.e.: Skywatch® Eole, Skywatch® Meteos, Skywatch® Atmos. 
Let's start with what these three models have in common. First of all, the already mentioned large propeller which accurately measures wind strength regardless of its direction. Secondly, a stronger and more durable construction compared to the Xplorer. Thirdly, a strong aluminiumbase with a thread (1/4″) for mounting on a photo tripod. What makes them different is the individual measuring instruments.

And so Eole is recommended by the manufacturer for wind- and kitesurfers as a device that reads very precisely the speed of wind and is also unsinkable.  
 
Meteos, with its even greater variety of functions, will also work perfectly as our handheld weather station during expeditions not only to the sea, but also to the mountains where the knowledge of the actual and perceived temperature will be important.  
 
The Atmos, on the other hand, thanks to an additional hygrometer installed, will allow us to plan our adventures even better during sports and will make it easier to control and monitor the influence of weather conditions on crops in agriculture. Precision, ease of use and many other functions of Skywatch Atmos make it an indispensable device for farmers. Atmos will make it easier to make decisions before spraying crops and controlling the livestock environment.

Smartphone Weather Stations  
The last group of Skywatches that we will look into are small and handy stations that connect to your smartphone via Bluetooth, i.e. the Skywatch® BL models. The BL 300, 400 and 500 models are ideal for such activities as: 
  • sailing 
  • wind/kite- surfing 
  • paragliding 
  • hiking 
  • agriculture 
  • construction site 

This small device with a diameter of 26mm provides instant measurements, graphical display of measurements with momentary, minimum, maximum values, tracking mode with automatic recording of measurements and GPS coordinates, it even allows you to share the measurements on Facebook, Twitter, Instagram and bl.skywatch.ch. With the digital data storage, you will also have an overview of the measurement history and all data will be displayed on the map.  
What can we measure with BL? It all depends on your model.

As you can see, Skywatch gives you the possibility to choose a meteorological measurement instrument ideal for our needs, with high measurement accuracy and made with Swiss precision. All of these devices will surely prove themselves as perfect windmeters on the spot, and the higher models will also prove themselves and facilitate decision making during mountain expeditions, walks in the city or even in the cultivation of plants. Every weather-dependent person should be equipped with such wind meters and meteo stations .
