Does the iron range on the 400 go from smaller to larger iron sizes or vice versa and also if looking for iron relics of larger sizes like a knife w/o hits on nails etc. What should I enable or notch out? Also am i not using the sensitivity setting correctly to accomplish this. I've read different statements that discrimination deals mainly with size vs depth but on my unit if I go below more than one or two levels I seem to lose almost all signals. Any insight on using my 400 is appreciated.
