Inside is clean and looks new. Very light weight and specs manual can be obtained on the internet. Appears to work good.
Unknown calibration date so I would recommend for serious work. Pictures show it detecting a fiesta ware bowl and radio clock dial. Nice gsm 110 geiger counter with open end probe for detecting alpha, beta, gamma and x-ray emissions.
You can start prospecting right out of the box. Uses 2 9-volt batteries, included.
