[quote Larry (IL)]I....the Explorer will go deeper and find targets in iron better than the DFX.
Larry, I respectfully disagree with you on this emphasised point. It is too sweeping a statement and very 'non specific' regarding both the targets involved and frequency used for the DFX search mode..
It is unrealistic to compare the depth performance of two machines utilising DIFFERENT SIZED SEARCH HEADS?
Come on, be a little more fair and subjective.
I agree with most of your post.
Of course, the Explorer will find SOME targets deeper than the DFX, but not necessarily ALL targets.
***********************************************
You say:-......The Explorers are reading conductive and ferrous content of the targets and giving you a reading of the difference of the two.
This comment needs some slight corrections:-
The Explorer is reading the target's conductivity and INDUCTIVE factor of the target, and giving you both factors ( not the difference).
The term 'ferrous' was a convenient one used by the non-technical advertising personnel, and obviously not really appropriate.
If you think about it, where is the the ferrous content in a silver dollar or 22 crt gold ring? Of course there isn't any, but the Explorer shows Fe 12. Con 14. for example. Which is acceptable for non technical convenience,as long as you don't interpret it too literally.
The true fact is that the figures relate to the frequency related phenomena called 'The skin effect'.
You also say:-.....The DFX and other detectors are sensing the conductance of the target and comparing it to the conductance of the of the ground. That is why a ground balance is necessary for the DFX as a reference point.
The DFX does not compare the conductance of the target with that of the ground.( I wonder where you derived that information from?)
Conductance figures are normally derived from the 'time' difference between the TX reference 'point', and the target's relative 'shift'.
The words 'time' and 'shift' are used for convenience rather than technical accuracy. The factors involved relate to the effect a target has on the subsequent advancement or delay (Phase shift), caused to the received target signal, when compared to the timing of the original transmitted signal.

If you are fortunate to own both the Explorer and the DFX, then you have a two of the best detectors (There are others). Each detector's advantages over the other, resides in your intelligent use of each one for the appropriate site conditions.
It is so easy on occasions, to fall into the forum mode of loose comments of over simplified comparisons.
We've all done it, one time or another, but given the chance to contemplate our responses then I think we can be a little more constructive and informative for the sake of those who may benefit from your usually helpful observations......Best regards...MattR.UK.
