I have 15 Geiger Counter and Raspberry PI and software left. They are the same ones that I sold for $259 last year. So many people have been trying to setup a private geiger counter on netc.com that I will sell my remaining inventory to the first 15 customers. Email me at
staff@netc.com and sent a payment using Paypal to
staff@netc.com and I will send you the same GMC-320/PI units that was sold last year. Still has the one year warranty.
