Can a pi be notched not to see iron?.Vlf detectors use notch to disc. certain targets.I was told that whites could have had a disc. pi years ago and discided not to market it and came out with the surf pi instead off this proto type.A freind actaully see the proto type and said it got very good depth and didn't see iron at all.He said the guy used a notch system to take out iron.Just wondering,Joe
