Yes, I have five of them. It was suppose to be a group buy but a few decided they did not need them so ... hubby and I kept the extras for our family instead.

The major problem with these really old ones is they need a sample to calibrate the machines, and you usually can NOT even get anything radioactive to test them with.

AND, finding someone to check and work on them ... good luck.

The guy who did mine no longer works on them so ... they just sit in a box.

The newer models are much easier to use ... drop the big yellow box and go modern!
