I will limit my comments here to etrac and CTX.
First and foremost CTX recovers faster than etrac,,,meaning it should alert on more solo pieces of iron p than etrac ( same sized coils),, and should also alert moreso on nonferrous targets commingled with ferrous materials ( if detecting scenario will allow). Remember it is possible the detecting scenario won't allow either detector to sound off on a nonferrous target also.
Running 0 disc on etrac,,,really can only be done in a few ways,,,but these methods a are flawed somehat, 4 tone ferrous,,and 2 tone ferrous.
You can't run O disc in conductive mode ( nails and silver sound the same) tone wise,,,sure you could still find some coins by doing,,,by constant staring of screen would need to be down,,,plus you would likely negate allowing the etrac to alert you on a say coin higher conductor colocated with nail by doing.
2 tone ferrous
First and foremost,,only a higher tone is provided on nonferrous,,,so all nonferrous sounds the same. Also due to the way etrac is engineered,,for example 2 tone ferrous has a present tone break of 17 ferrous,,,meaning any target reporting with a higher than 17 ferrous number will report low tone-- hence operator will walk right by.
4 tone ferrous is similar,,,but has tone breaks at different levels for the 4 tones setup,,,but again an operator has no clue based on tone what they have condcutive wise under their coil.
CTX,,,different ballgame,,,first and foremost,,CTX engineered to give ferrous number closer to the 12 ferrous line ( using ferrous coin) process.
But even if the ferrous number strays off the 12 line,,an operator can by using combined mode,,,,have their tone bin pattern set,,for example to give non iron tone on targets reporting say all the way up to line 25 ferrous.
Tone bins can be set up,,,and using conductive scale,,,target conductivity can be determined by tone.
Even nickels can be set to tone in like silver coins if user wants.
So using combined,,,with CTX,,an open screen can be used,,,,op can hear iron,,and nonferrous targets-- depending on tone bin setup target conductivity can be derived by tone.
Hopes this explains.
Remember,,even using CTX,,depending on detecting scenario on any target,,,ideal tone that represents targets-- not absolute all the time,,,same with etrac.
But the fbs/fbs2 detectors, especially etrac and CTX,,far more accurate most times vs many other detectors.
At least my experiences. (Using conductive based program).
Thanks for the info, much appreciated. I didn't realize the CTX was that configurable.
I also agree with your point that just because two different machines can see and properly identify a known target, that isn't the same as initially locating a target. Sometimes a big difference.
