it does work, but the software feels unfinished
For Radiation Dosimeters and Gamma-Spectrometers KC761
This device does work, and it has roughly 2x higher count rate than the similarly-priced smaller spectrometer device from Radiacode which I also have. Despite the counting rate advantage, I do not find this device as generally useful because (1) it has lower energy resolution, (2) the software is far less capable and it provides less information (especially in the phone app), and (3) the batteries will run for less than 2 days before running out (Radiacode can go for at least a week). The larger physical size also makes it more expensive to make a lead-shielded "castle" to reduce background count rate.
One positive point: the KC761 can enable a real external analog pulse signal output on the 4-pole jack (alongside an audio "click" signal) something other consumer devices do not AFAIK, so you can use your own external pulse-height analysis hardware and software, if you are interested in doing so.

Hello, thank you very much for your feedback, we are improving our ui to make it easier to use. In the meantime we noticed that you mentioned that your KC761 can only work for 2 days, according to our tests, using alkaline dry batteries in the background radiation state can provide about 300h of continuous working time, which is too different from our tests, are you having the bluetooth function on all the time? Maybe provide some information so we can find the problem with your device's short battery life.
