QED Setup Procedure
QED Setup
The first thing I do is to go for a walk without the detector to check the
ground looking for ground depth, mineralisation levels, ground cover, etc.
So if a lot of bedrock is showing through, then the ground will be relatively
shallow, or if as I found recently -
a lot of vertical 20’ shafts with no rock
showing in the shaft for about 5’ and no bedrock showing
, then the ground
will be deep, probably too deep. This result determines coil size.
If there is a lot of highly mineralised quartz lying around - the real red
stained and fractured type (this can be found in the Victorian gold fields in
abundance, especially north of Ballarat, less red and more shiny south of
Ballarat), then the area will be highly mineralised, especially if you can pick
up the whole world with your magnet. This knowledge will help in setting up
the QED later. From experience, not all highly mineralised areas are the
same. For example, the quartz at Tibooburra is far less red but with black
flecks aplenty, similarly the FNQ Forsyth area is much the same.
Again if there is a lot of undergrowth, then a perhaps a medium/large round
coil will be difficult to use, so an elliptical may be a better choice and the size
dependent on the outcome from your ground depth analysis.
Walk back to the car to get the mighty QED ready for setup based upon the
above determinations.
1. Perform a factory reset (FR), so Gain 1, THS-A 30, Mode 3 and
THS-B 50
2. Set MODE: This step is coil dependent - so set Mode accordingly, 1
for small coils, higher for larger coils. E.
g. My 11” elite likes mode 3 in
mineralised areas, can get it to M2 in less mineralised areas. My 15
round EVO -
Mode 5, around the same for the 20” NF.
3. Check your THS-B NULL number and set to NULL.
4. Perform an MGB -
if you can’t get a good GB, go up a mode until you
can achieve a good GB.
