Ferrous # 13

[team sidewinder]

I have had my CTX for a couple of years now ( not a total newbie ) and is it just my detector but it shows every silver or clad coin as Ferrous # 13 ? Doesn't matter if it is buried or even laying on the surface. It seems like when I first got it, it would give # 12 ferrous on silver and clad coins. Everything I read in coin the charts show these coins should be coming in at # 12 ferrous. I also never go by just the numbers and rely on the tones but the # 13 ferrous makes me wonder is this common or not. Thanks for your input

Mine is never always on 12FE line. It jumps around from 11 to 13 all the time.

Thank you Jason. Here I was thinking it was just my detector was a fluke. Appreciate your input

Like Jason, mine is never 100% on the 12 line. 80% maby. What I have seen is that on quarters that are distorted by ground conditions, i.e. hunting
where a building burned out or having granular rust nearby, most always will give you a 13 fe #. The undistorted, clean, not shiny clean but no ground
minerals or burned buildings or rusted out and disintergrated metal nearby I will get a 12 fe #. Now, I also get 11 fe #'s also on pennys, nickels, dimes
but never a quarter, yet??? What I have done that has helped is to change speed of swing, turn 90 to 180 to 270 degrees to see if it changes and it
almost always does come off the 13 to the 12 on a quarter at some point. The strange thing is that when the smaller denominations come in on the 11 line
I can't ever remember getting them off the 11 line. Who knows???

Thanks. The conductive numbers are usually right on. Coming from a Minelab 705 with no ferrous numbers it really hasn't made me miss any coins but wondered about my # 13 ferrous numbers. I just wanted confirmation from more experienced CTX users on this.
