I am most interested in a test with a standard target, like a nickel, that gives the same results no matter where. Then I can judge if my detector is running like others’. OBN’s videos show you can get better results when the target is in the ground. Nickel 19” in ground, 16” in air. Mine and Stateguy’s were doing 11-12” in the air. Transfer this to Pi’s new thread if he does one… Yes, one reason I do airtest. It gives a base line where (Identical) machines can be compared since conditions can vary one location to the next. Also one can learn so much when testing different audio systems and how distance affects the characteristics of different targets. 3 Link to comment Share on other sites More sharing options...
