Review on Thickness gauge CarSys DPM-816 PRO (Fe/nFe) by Czeslawa Winski ᠌

Before that, I used Etari 555 (a good thing), but this one gives readings much faster and they are accurate, different types of metal have a different sound signal (you immediately understand where the color is, where the black is, etc.), it works quietly up to 3000 microns. There are calibration plates in the kit, but they have not come in handy for me yet, the device is already calibrated out of the box. It is powered by one AAA battery, it is included in the kit, but it is right for the first time, I changed it after a couple of months. Overall impressions are very good, the biggest plus for me is the speed and sound signals
