These aren’t that great........unless you understand how to use them and know their limitations. Keep in mind that the 715 and 717 series are only useful in certain circumstances as in an actual nuclear attack. If you want to experiment and learn about radioactivity and detect radioactive items that wont kill you then the model 700 is more useful. They are also very bulky not something to carry around for a warning device. There are much better options however if you like history and want something for a fallout shelter these could work for you.
