They claim a Esmog Spion 5G measures LF between 50Hz - 250kHz and RF between about 50MHz - 8 or 9GHz depending on antenna used. I cannot test if this is true (to know you would need a signal generator for all frequencies which I cannot afford), but it's one of my favourite EMF devices, it reacts strongly to EMF most other devices are a lot less sensitive to or don't even detect at all. More videos come in a couple of weeks. I would like have seen more modes on this one especially, especially for LF, because sometimes you measure so much with it it's harder to use for pinpointing and knowing what you measure. If you don't extend the antenna it's less sensitive and then you can pinpoint more, but even then it's often very sensitive. I like this device a lot for EMF sensitive people, you shouldn't miss much from electric fields, not sure everyone will like it, but I love it.

mrb meralaizer. does it detect the signals coming from the pwm signal generator. such as 5 khz, 10 khz, 50 khz. especially esmog 5g
