[QUOTE="grubstake, post: 230145, member: 4012"] For most detectors with a discrimination mode, even the lowest setting isn't actually zero (ie. all metal). In Tesoro terminology, a full-ranging discrimination starting from true zero is [i]ED 180[/i] (meaning a full 180 degrees range, from minimum to maximum), however, many of their machines and other makes/models are actually [i]ED 120[/i] discriminators, meaning their range is truncated at the bottom end of the scale. This is especially important for Claudius' application, because he wants to hear iron/steel, which is the first metal that detectors discriminate out. I'm wondering whether a detector with an iron audio option would be helpful for his specialised purpose? On a detector with notch discrimination facility, notching out everything except the low range (iron/steel), would be an interesting experiment too. [/QUOTE]
