Just something to keep in mind

Hunting my go to clad grounds which has yielded some silver coins plus some silver rings but yet no gold rings and this is in a pool area. This morning after digging good signals, I got a 70 using a 12 Khz program. My wedding ring comes in at 70 so I thought I'll dig it but it probably is a pull tab. It was clad, a quarter and a nickel in the same hole. Now I get a lot of 70 readings that have been pull tabs but currently, as this place is loaded with clad coins, bypass them. Wonder how many might be a high and low conductive coins target being dragged down. Same thing could happen with a silver coin and a lower conductive target in the same hole dragging the TID lower.

Yep, good advice there...lots of multidenom stacks in clad areas...I guess a fellow could go out in the yard and practice stacking or tight slanting multidenoms for reference...I've found a bunch myself, and enjoy giving those squirrley signals a poke. This sure is fun eh?

Good post! Any high # is worth a dig!

Good advice DA, I have found the same to be true. Sometimes the audio can give an indication of multiple targets while the VDI remains the same.
I got an 88 the other day at 18khz. That usually indicates screw cap, soccer cleat, or small silver. It was a zinc penny (82-85) stacked directly over top a clad dime (91-92).
There appears to be conductivity blending with very close proximity targets that net an average of them on VDI readout.
Not so much with iron, however I have seen it raise the target readout of high conductors like coins by a couple points.
