I welcome the new library! I have used a RadiaCode 103g for more than a month. I also have a more conventional NaI:Tl 5cmX5cm scintillator+PMT in my basement with 95 lbs of lead shielding (as lead shot). I'm painfully familiar with detector drift and recalibrations required with conventional (amateur) detectors. In my opinion the RCs are game changing: their calibration ranges from good to excellent, in that I can import a spectrum into the (exceptionally useful free Sandia National Labs) tool InterSpec, extremely quickly identify peaks and the relevant radionuclides. The RC is very compact with a well-defined detector volume (because it IS relatively small). If there is a weakness, it is that it's mostly targeted toward running on a smartphone and support for iOS vs. Android has lagged a bit, though very recently an excellent update has appeared for iOS. I have tested in on a variety of spectra (137Cs, 232Th, 60Co, 133Ba) and for long background counts and am quite happy with the resolution and stability. I have yet to use its interface to GPS data (I already have a bGeigie Nano built from a Safecast kit). Its impact is that almost everything one might like--count rates, dose rates and net dose, data logging, and GPS interface is all there in a sub pocket-size unit.
