Silver reading on the r2?

[Myk31uk]

Hi guys,just wondering if any of your owning the Racer 2 have found silver reading in the 90s like the screen says?I've found silver spoons/coins but they have came in around the 75 area I've had big bits of iron coming in the 90s that's it,just wondered if I have a faulty machine or others are the same?cheers

I had a Washington come in at around 89. If there is iron it may drag the id # lower. I always notch out the highest 2 or 3 digits to help with false wrap-around readings.

depending upon what the target's size, shape, orientation to the coil and ground mineral make-up might be, and we can't forget the target's metal percentages, either.

Spoons are not the same size and shape as coins, which are generally roundish-shaped, and spoons usually have a different alloy mix if they also contain some silver content.

Remember, also, that silver coins from one country are likely to be a different size [size=small](thickness and diameter)[/size] as well as metal alloy make-up than those from other countries. Even similar coins can vary based upon the metal mix that was used, the amount of wear, etc. Here are some US coin samples I just air tested using my Racer 2 w/7X11 DD coil. There was no ground mineral to influence the numeric TID read-out, and all the coils were moved past the search coil's center axis in a flat-to-the-coil orientation for consistent read-out. The coil-to-target distance was about 3" to 4" from the center axis of the coil.

Modern 5¢ coin ........... 30
Modern Zinc 1¢ coin ... 67
Modern 10¢ coins (2) ..79 and 80
Silver 10¢ coins (3) .... 83 to 84
Silver 25¢ coins (4) .... 88 to 93
Silver 52¢ coins (2) .... 94 and 96
Silver $1 coins (2) ...... 96 and 97

For what it's worth, I never try to rely on a 100% accurate TID because it just isn't going to happen. There are too many variables involved, as I mentioned earlier, so I just use a 'common' assigned number to best guess what target I might have located, and I allow a variance of 1 to 3 numbers on either side of the 'average' or 'typical' air-test response for average depths and favorable site environment conditions, to allowing even more TID spread, if I am hunting in a trashier site, dealing with more challenging ground mineral conditions, or knowing targets might be deeper than average or potentially canted or hampered by a near-by offending target.

Just my observations.
