I used to have this unit before and it worked fine. Fine meaning I could get decent accuracy using the calibration films included in the package. this unit i got is way off. for example, I test using the 102 micron sheet on the metal plate, it reads 126 microns. other results 1. using 252 micron sheet, i get 305 micron reading. 2. using 505 micron sheet, i get 624 micron reading. 3. using 1020 micron sheet, i get 1010 micron reading 4. using 51 micron sheet, i get 59 micron readings. it claims that the error rate is 1+/- % another issue is that my old unit which already broke down was able to read on non-ferrous metals. now it cannot do that anymore. so dissatisfied with this purchase i can consider throwing it in the trashcan as it is useless at such large margin of error.

My last one still works great, for years now. Need Manual and kit to reprogram as needed. Touch button labels wear off after a year or so, but for the price, it's worth any extra effort. I use it year round outside in all conditions. Buying this one for a back up
