Did some tests of my own air test Fors Core..... discovered something amazing.

Placed a Dime about ¼" from the middle of a pull tab. Dime by itself was coming up at '85' solid. Pull tab alone came up at 62-66 depending on the coil direction...

Sen = 85; Mask = 10; Mode = DI3; 5" coil.

swinging the 5" coil lengthwise both ways gave me a mixed signal with the numbers occasionally climbing up to the 80s.

When swinging the coil at a good 45 deg, I could get lots more high tones while moving the coil away from the Dime it eventually gave me a solid '82' on the screen. So by isolating the Dime I was able to get a diggable signal and VDI. Sensitivity had no efect. As a matter of fact, at '99' sensitivity it was harder to get any high tone when swinging end to end.

Here is the amazing thing. I bumped up the disc to '80'. At this point it was giving me a short high tone EVERY SWING with a VDI of 82 no matter which direction I swung the coil over the targets. So the high disc actually helped isolate a high tone and solid VDI. I've never seen this in any detector ever! The high '80' discrimination did not appear to affect depth.

So I guess I have to start digging those 'iffy' 82 signals.

Similar statement I and others made about "Racer"
{ "I've never seen that before on any detector!" }

I'm not able to edit my post. Where I state that the coil wa swung 45 deg, should read at 90 degrees.

I just tested the Core with the 11" coil. Amazingly, it was almost as good in separating the targets. It still gave me mostly good numbers. Mostly 82 but sometimes 80-83. It did give me a much shorter and scatchier blip. This is with disc set at '80'.

Tests like these give me a lot more confidence in my machine.

I need to diuplicate this test with the f75 and 5" DD coil at DISC=65.
