Whay Coins Skew

I have found so few good targets in the same hole touching iron to be considered insignificant as far as I am concerned. However, in heavy trash areas the numbers of iron targets that influence the reading of good targets are significant. I am not sure how much that is but searching in all metal causes me to be confident it is worth considering. This has lead me to do some testing while hunting and in the test garden to see why a coin will skew to the left of the screen.
A quarter touching a piece of iron that is about the size of a human thumb can be used to duplicate these results. A number 16 nail can be ground down and the grinding used in place of iron ferrite. One of the engineers told that to me so this is not something I came up with. I used a rusty piece of iron simple to see how ferrous objects skew silver reading and used the iron touching a quarter as I indicated.
A clad quarter reads 0/29 lying on the ground or if buried at 8 inches. If the quarter is placed in contact with the iron the reading changes to 31/28 when the coil is swept toward the two targets so the coil crosses the iron first. On the return swing the quarter is hit first and the reading changes to 15/24. Using ferrous sounds and the setting I hunt with a low medium and medium low tone are heard. The quarter with no iron touching has a high tone at 0/29 so consider this for what follows.
A digital reading for ferrous of 16 is the same as and Iron Mask setting at 0. An iron mask setting of -1 then would be ferrous 17 and so on to 31. If iron mask is turned on and the screen is set to 0 then what we see and hear changes. Instead of the crosshairs jumping from 31/28 to 15/24 and the tones going from low to high and high to low we see the crosshairs locked at 15/24 and hear a mid tone.
The quarter has reading have been skewed to the left and since the iron mask blocks the 31/28 reading we don
 
Here is the picture I took from other sight with following remarks:
"A and B are where high and low coins will
show when next to iron. The tone will sound right but the curser may stick to the left.
The rejected left side is the same as a (-:geek: Iron mask."
It is really very few good targets which touching the iron but much more are 1-2in nearby. So the reading will be averaged and crosshair will be on the border of IM-14 or 8 giving an idea to dig. With left upper spot (Fe coins ) it might be almost impossible to to take right decision ( IMHO ) to dig or not because crosshair will stick in the top left and the sound will be very slightly higher then pure ferrous.
As to me I prefer pure IM-14 to 12.

Sorry, the bottom line is coins don't always read where we think they will. Beware of AIR TEST!
