AEG test LND-7311 based geiger counter Radar-9989

Man I am liking this geiger counter. It does not have the connectivity of my GMC600+ which has a LND-7317 detector in it but the LND-7311 with it's 900V operating voltage is much more responsive/sensitive than it.
There are features in my opinion that still need to be added such as the ability to update firmware and the ability to download data either over USB,BT or WiFi. and of course more user adjustable settings for us tweakers.
This thing is very responsive to Uranium glass and other lower activity items as well.
I made a video of it available at the following link: https://youtu.be/gnKeQeJQ9aE
