[QUOTE="Goldpick, post: 321771, member: 1695"] A coin should not deviate by that much on air testing, you must have something else interfering if it is jumping all the way from 8 to 40, even shallow the medium depth coins should be pretty accurate if sitting flat in the ground, less so when lying on an angle. The other scenario is if you are testing in/on the ground, you might be picking up other targets in close proximity making the numbers jump around. Also the deeper the coin the less accurate the numbers will be, I like to treat them as an indication rather than a certainty, and prefer to learn the tones which hold more accuracy at depth. Here's a link to 705 target ID's, should help take out some of the guess work. :) [url]https://www.prospectingaustralia.com/forum/viewtopic.php?id=15178[/url] [/QUOTE]
