Of course you can still discuss whether it is necessary to add itself as a unit. But one can also discuss whether it is necessary to fly to Berlin, if you can go by train, for example. This discussion is about the same sense and endless. I fly personally (where I can) and I measure the radiation itself. I do not consider therefore for paranoid and thus constitutes the not for me in question.
The wheel rate combines for me a number of advantages:
Ease of use, low price, reliable functions, European craftsmanship.
First of all: the comparison with a professional device not win the wheel rate. It is accurate, but it creates a good overview, namely whether it is large or small degree radiation. You can see the type of radiation can not be reliably ascertained, but you get a relatively accurate picture of the amount of radiation. You have not previously read or deal intensively with the device. It has only one button and then counts clattering high. High speed, a lot of radiation, low speed, low radiation. Number (CPM) divided by 17 = 1 'Sv. It's that simple.
The same technology that is used in wheel rate, is basically in any better digital camera and smartphone. The wheel rate but is less sensitive to electromagnetic radiation than the smartphone and therefore to handle trouble. If you use the smartphone as a radiation meter, it may be that you accidentally mitmisst light to very bright places. This is ruled out at this device.
For private use, the device is quite enough.
