Minelab Vanquish 540 & Equinox 800 Tone & Number Test

Testing the Minelab Vanquish 540 & Minelab Equinox 800 metal detectors. Trying them out on different items. What do the tones & numbers tell me? Bonus Gold & Silver acid test. I have been asked by a few people what the tones and numbers tell me and how I know what I am finding. The truth is, we don&really know what is coming out of the ground but you can get a pretty good idea based on what you see and hear. #metaldetecting
