I never detected at the 3 kHz frequency and would like to try it out. I read some info on that coil and it seems to be good at finding coins in trash. I have a few places that are either bottle cap/pull tab or nail infested and I know that there is century old silver in there as well. How would this coil do in moderately to above average mineralized soil ? Users say they can easily pick out coins from trash with it but how does that differ from the 7.5 or 18 kHz range ? In other words, how does it make identifying high conductors easier ? Sound and or ID ? What about modern alloy clad vs silver ?
Any negatives apart from price ? Any info would be appreciated. Thanks.
