Review on RockyMars Non Ferrous Substrate Indicator: Accurate Thickness Measurement and Analysis by Gilbert Pfaff

Excellent product, very accurate and reliable. The screen is colorful and of reasonable size. One of the advantages of this device is that you always have the option to calibrate using the supplied calibration kit. I've been using this device for about two weeks, it works perfectly. The only downside is the software, the manual says that to get the pc software you have to go to the website to download it but the software is not available on the website.
