ORX, APEX, LEGEND Target ID Accuracy

XP ORX, Garrett Apex and Nokta Legend. Target ID accuracy on a surface US nickel, 4" deep US nickel, 6" deep US nickel, surface clad US quarter and 6" deep US quarter in iron mineralized ground. Only one of these similarly priced detectors will pass this test by correctly identifying these targets. I could have substituted a pull tab or can slaw for the US nickels with the same results.
