Target ID Numbers
Published: January 8, 2010
Target ID numbers (TIDs) are what are shown on the display of your control unit to indicate what you have detected. Today’s metal detectors are smart enough to know what you are digging before you dig it – in most cases.
Every model of every detector will show you a number, or in some cases, a picture, of what you have detected. This is great but not perfect. On my Minelab X-Terra 705 a TID of 10 can be a nickel, a pull tab, or gold. A quarter will show up as a 40, 42, or 44. Nothing is perfect and the numbers can be affected by soil, angle of target, and a host of other things.
They are good indicators – but not perfect – so it is recommended that you dig every signal – since you really don’t know what is under the ground.
Another thing to remember is – TID list may be available but are usually only indicative of American coins. I had just gotten the hang of my machine in Hawaii and then went to Thailand and had to identify and list Thai coins on my spreadsheet so I would have a good idea of what I was digging before I started digging.
Below are a couple of TID lists for Minelab X-Terra 70′s which are almost identical to the 705 and have been very useful to me. Hope this helps.
I recommend that you make a small spreadsheet similar to the above to track your machine’s ID numbers.
