Give the Tek Omega some thought. IMO it has quite a few plusses over some of the others mentioned here.
Lightweight and equipped with the 11" DD coil the balance is still quite good.
Quite sweep speed tolerant which is nice when going from cleaner areas to working slow in iron.
Target seperation and recovery is very good in
all of the tone modes.
At high sensitivity/threshold settings (just one knob does it by the way) it does not take on the love for iron like others when supertuned. Some but not much!
Of the newer digital machines I have used it has very descriptive audio in both the 1 or 2 tone VCO modes or the more normal 3 or 4 tone modes.
TID is better and more stable than the MXT at depth. No contest!
Has plenty of oomph to make up for some coil height in stubble.
Set at small iron reject it is one of if not the quietest machines I have used.
The 7.8 Khz freq allows good performance in both plowed and fallow fields.
You can set the audio freq/pitch in all metal to your preference and the setting also carries over to the P/P mode. nice!
Minuses
Perhaps not as important to coin hunters but for relic hunting an all metal toggle would have been nice. It is a slight pain to have to turn the disc knob to all metal to get a better feel on those iffy targets and then switch back to your preferred disc setting.
The screen plastic needs a protective overlayer to prevent scratches.
Can you tell I am impressed?
Did I say it's quiet in iron?
