Myself and a number of other detecting friends have been using the Deep programme with considerable success.
Having said that a friend found a iffy signal from a prospective find and said would you dig this?
I ran the Deus with the H/F coil at 14 kHz over it.
The XY screen was showing a leave it alone with broken circular lines in the centre of the screen.
My answer was no I would not bother.
He went ahead and out came a rather tatty hammered penny.
I asked him to place it on the ground and straight away the screen was giving a strong bottom left to top diagonal right line.
The answer is, dont just trust the visual screen all of the time when using the visual display.
Happy Hunting,
Jerry.

When I used the XY screen a lot I had a couple of small hammered with that sort of off-shape circle signature. I think it may be simply down to small/deep targets not providing enough info for the XY to provide the non-ferrous diagonal line.
Still, whatever the technical reason for it, I learnt early on that if I only dug the "dead cert" NF diagonal XY signatures it would be a surefire recipe for missing good targets.

I agree with you both. I have also found that if you get a hint of a good tone in an otherwise iron buzz, and it gives a diagonal left to right within the usual spider squiggle - is worth a dig too!

This is why I moved away from the X/Y. I would imagine that a seal matrix, cruciform brooch, and other such wonderful things would give a very erratic shape, and quite possibly a mixed tone dependant on the conditions.
Jerry - when the HF coil is in 14khz, surely this is just a 9 inch coil at 14khz signal? Or am I missing something about the way the white HF coils and V4.1 are set up? Just curious, as a non HF coil owner I'm assuming this would be no different to the black coil on that kHz, but I could be missing something.
-
Hi Keith its just the same with the black coils.
Whether on 7 11 or 17 kHz.
These days I seem to use the 9" HF coil all the time.
Happy Hunting,
Jerry.

Many thanks Jerry.

What size coil was you’re mate using ?
I always use the mark one ear drum and dig technique
-
With the black coil test today the 11".
On the day of the hammered penny event the 9" circular H/F.
You are quite correct about what the user hears, but even then at times we can all get mislead. ;) Jerry.

You’re right Jerry I got a lovely quite signal it was a shottie laid on its side can’t win them all
