auminesweeper Posted May 27, 2015 Share Posted May 27, 2015 G'day Folks, I have been testing the coil /Machine out today and I thought I would post a couple of pictures of how sensitive the standard Coil Is for future reference, The Small Bit is less than a 10th of a Grain and the larger Piece is around about a 10th of a grain +/-, the Scales fluctuated and the Bigger piece varied up to 0.2 grains The Smaller Piece was giving a Signal at 2 Inches and the Larger piece was reporting at 3 inches, John 1 Link to comment https://www.detectorprospector.com/topic/993-gmt-5x9-coil-test/ Share on other sites More sharing options...
