[QUOTE="XLOOX, post: 622739, member: 16174"] mbasko, I know that small bits need faster switching and lower delay from switch off to receive to detect them as the eddy currents decay quicker in smalller bits, but does a lower delay actually reduce detectability of bigger bits in any way in the SDC or in general? I am thinking to my TDI SL which has adjustable delay from 10us to 25us and small gold performance falls off noticeably above 12us but I didnt see any lower depth on big iron/alu at 10us vs 25us.
