Test bed results are just that - test bed results.
You know already:
A) there is a target there
B) what the target is, how deep etc.
C) the ground
You can also adjust settings to suit all of the above & readjust to obtain optimal results for that test bed. This cannot be replicated in real world situations where you don't know some or all of the above & don't have the luxury of readjusting optimally over known targets to suit any ground or other changes.
I prefer real world results & the SDC certainly produced for me in the past. It will be an interesting comparison once I try the small coil. With the 11" coil there is a definite diminished signal in higher modes on various targets I've tried with various other setting adjustment like bias although I haven't dwelled on it to much AEGPF. IMO better off using as low a mode as the ground, coil & other settings will allow. It's still got good sensitivity.
In reality the SDC is vastly different to the QED. Both have pro's & con's so trying to say one is better than the other will only go around in circles. Some people will prefer one over the other for vastly different reasons! Just like GPX vs SDC really.
