I acquired a GMC 600+ some time ago. I have had some interesting results from my brothers classic watch collection and a few "interesting" results from a couple of our beaches here. I live approx 30 miles away from Sellafield.
Due to the time that I have had the unit is there anywhere that I can download and update the firmware on the unit (I haven't found anywhere on the GQ website).
If someone could point me in the right direction I'd be most grateful.
Hi Orange-Phantom, thanks for using our GMC-600+ :D, please email me your device serial number under Main Menu -> About -> Serial # then I can generate an update for you.
Hi Orange-Phantom, I cannot remember if I received your email or not or have sent your the firmware update. Please send me the serial number to this email: mark@gqelectronicsllc.com
