Seems to be the case with mine. In the manual they say 12" air test on small coin & IDs most items correctly in most ground to 8". When I did the air test, small coin high tone consistent to 5"-6", variable tones 7"-9", nothing beyond that. So I assumed my detector must be defective. Think I did the air tests in the house at sens 60-70 & when used it outside, sens 40-80 depending on area to get rid of false signals & nothing found beyond 4". F1-F7 no difference.
But then I tried all metal. Wow! Now it actually does detect a dime in air test at 12". Didn't even turn up the sensitivity! The numerical ID seemed more consistent, & none of those false signals from electrical interference or ground minerals. I started thinking, this could find deep coins & probably ID accurately at good depth.
But it seems the disc is more like a mode for those who want the multiple tones so they don't have to look at meter, with the result being instability & false IDs beyond about 4" if not no detection in some ground. So it seems the disc mode is the ideal for shooting clad & for serious deep detection of old coins with good ID, the all metal mose must be used?
Is this what others are finding to be true or is my disc mode defective? The manual I don't think said anyhting about mode & settings they used to get the 12" dime air test & good in ground IDs at 8". If they meant in all metal only, wish they'd said so. Thought the detector only had the disc for potentially going deep without having to dig everything. Didn't know or forgot the numerical ID works in all metal & just expected the same instability. Glad I kept it long enough to discover this. All comments apppreciated. Thanks & HH, George (MN)
