                       Hi!
  I am about to buy a GQ Geiger counter which I intent to use just for fun and curiosity around public areas in Germany, and maybe checking out a few rocks I collected. I also would like to make some time series measurements and look at the graphs.
  After reading a bit in this (really great!) forum, my choices came down to either the GMC-500 or the GMC-500+. I find the price difference between the two negligible, and the GMC-500+ seems to be a bit more fun to play with due to the two tubes. 
  However, after what I read here, I am not sure if the 2nd tube also makes the devices readings hard to interpret due to the tube interference.
  Furthermore, I suspect the 2nd tube will never register anything anyway for me, since I don't expect to come across any seriously radioactive material anytime soon.
  What do you think, should I get the GMC-500 or the GMC-500+? |

                      |  Definitely the GMC500 +, because the two counter tubes can operate independently of eachother.  The price difference is minimal.  Why buy a Trabant when you get a Mercedes almost at the same price? |

                       If as with many of us you get kind of hooked on seeing what's hot out there then there is not a better value than the 500+ (and I've looked at a lot of meters).  And it's only going to get better as new firmware updates open more functionality.  Happy to guide you through the menus.  That's what the forum is for.
