RonBeck62 I haven't bought one, because I don't like the specifications. The count rate is very low, and the J305 tube pictured is a cheap one that only detects Gamma and HARD (high energy) beta. That's useful if you want to see how many days you have left after a nuclear war. If you want to check for Radon (alpha and some soft beta) or go prospecting for Uranium, then you will need a different tube.
