With Eddy Rondags permission - here copy - past one of the most interesting and useful for all Vista users feedback, which I ever have read, published yesterday in one belgian facebook group - about Vista GOLD and EPIC coil:
"Ok Tom especially for you and Vista users.
I hunted again at the roman villa at S'Herenelderen.
Heavy searched by lots of detectors in the past... but recent visited by Tom and me with the Vista gold.
The field is used intensivly from Roman times untill now.
The place is covered in coal and iron patches during the ages.
Nowbody will belive me if i say there's an iron piece at every 10 cm square....
And so we used the most sensitive equipement at the moment with a 14" coil....
When we just hold the coil and do nothing at all: we got an average of at least 1 iron
patch, a piece of coal, pottery or junk piece copper, led, messing, sink during the ages
just beneath our coil.
Swing the coil around from left to rigth (an nothing more) results in at least 10 signals
from different depths and all different kind of materials. Nobody will believe me... they
have to see it with own eyes to understand the massive, intensive use of a an old field.
Now.... the problem: How do we reach the old objects trough an iron and coal layer of
proximus 30 cm thick?.....
We all see the many roman pottery at the surface so everyone knows it's a Roman
field...
You can run the field like a maniac and get the large objects by luck.
But what with so called "Empty" villa's?.... How empty are they?....
After the large coins many detectorist lack the tiny objects by 2 reasons.
1) They are in a rush and swing with outrages anger and impatience... giving the
machine not the time to react at the smaller signals.
2) Their equippement is overaged, ther .....simply lack depth and accuracy to
reach it.
3) The parameters must be adjusted to the kind of groundconditions your'e in: every
field is unique so every field requires unique parameters: that's why every machine is
adjustable according the conditions of the moment. To understand the ground beneath
you, and the things you want to find you have to ask your self how much time will I
spend on it....
Tom is my witness in this i tried 3 different ways of adjusting the Vista properly
especially for this type of field.
1) First i used the 14" with almost no ground balance and everthing at maximum: (all to
maximum depth)... works good at other fields but not here and not at some other old
fields quite similar to this one.... Yes i found coins to but over multi signaling masked a
lot smaller objects...
2) I Even switched to the standard 11" coil witch is more stabil at iron soil: but with
groundbalance at half it lacked depth to reach the layers at 25-30 cm where the tiny
Roman things where. I noticed a very stable an clean and accurate searching but the
depth was not enough for here.
3) I uesed the 14" again but with heavy groundbalance of 14-15 O clock: and i tried it
out: you pick up trough the medium iron patches and coal (it dissapears) but it still
maskes when a medium iron patch is at the same time with a small coin in the
diameter of the 14" at the same time: there's only om sollution: every signal has to be
checked several times by coilscanning in different angles: it takes a lot of time and
effort but it results. Also Groundbalance at 15 o Clock means decreasing depth
seriously... but at this fields i think everyone rans out of options.
So this is what an "empty" Roman looks like for a 3 hours hunt with Vista Gold .... i
only did a 3-4 rows at slow speed the percentage of the entire field which i scanned
today means nothing compared with the size of the total field but it gives an
impression of how much others left at the field by iron masking.
I placed the Iron paches also: when groundbalancing to 12 O clock: you will pick up
medium iron patches in high tone... turning groundbalance to 14./O Clock will eliminate
them in iron signal .... but this has a price in depth..... so only if there's no other option
Even then small objects can be found: using dicr starts to reject things.... im no
favorite of that (knowing how tiny the smallest European coins can be).... so my
frontier discrimination will be only ground balance in worst case scenarios
You see: it's no longer luck when we pick the smallest objects between the iron
patches... we got a strategy for it and we got the equipement for it too: this is what all
the others left for us at the "EMPTY" fields: thank you guys"
