silver chains

[don tyler]

Has anyone picked up heavy silver chains in the lower vdi numbers ?

I have not picked up any silver chains, but my guess would be that heavy ones would at least be in the mid range of VDI numbers (40>>>)

There would have to be something else in the hole with it. Big silver screams. I just thought of something though, German silver and alpaca silver from Mexico are nickle and tin without any silver at all. Those both will ring up lower and appear to be silver upon first inspection.

My last heavy silver chain rang up as a zinc penny, in the 50's.

thanks for your input, Don CoCo tyler

Wow I learned something new... I just checked a 25 gram chain coiled and uncoiled with 3/32 links. Both coiled and uncoiled it was reading low from 4-25 depending on orientation. Another reason to dig all the pulltabs........ but the silver should hit on the 2.5 best.

Note to self: do not assume anything and dig all repeatable targets including zincolns

I'm not so sure on the 2.5 being dominate in the 4-25 range, can you check that chain again?

Best Frequency to Use is determined not only by metal content, but also size and thickness. For thicker coins with high silver content there is no question that 2.5 kHz will hit harder than 22.5 kHz. For US nickels 22.5 kHz will hit hardest. 22.5 kHz may also work best on small thin coins, even those with high silver content, due to skin effect. High frequency may also work best on low silver content coinage. 7.5 kHz is typically better on copper coins. Test the detector for the items you want to find. If all you want is US silver, then you should use 2.5 kHz. If all you want are thin gold rings or small nuggets, then select 22.5 kHz. If you want the best depth on a wide range of targets, use 3 frequencies.

Large copper (Large Cents and many Colonial Copper Halfpennies) will also hit hardest on 2.5KHz
