Are the metered detectors better able to see subtle differences in targets than the digital id machines? I was kind of thinking that with the analog meter you should be able to see slight differences in target id as opposed to the digital readouts that may lump a 34-36 into one category. For example if you were hunting an old site that had a lot of empty brass or other trash items and you knew they hit at 38 on the analog meter but nickles hit at 39-40 the digital may just put those numbers in one area but with the analog you could see the slight difference. Yes, no? Thanks.
