"Dear Bill Southern
The guys that did the testing are NOT having problems with the setup
of the 4000.They are extremely experience prospectors and users of all
ML machines and in fact have taught hundreds of others how to use ML
detectors over many years. Their testing over a number of days CLEARLY
shows that in sensitive and smooth that certain nuggets at certain
depths are NOT detectable with ANY size mono coil in sensitive/smooth
with the 4000. This has now been observed also on some VIRGIN nuggets
in VIRGIN ground ie nuggets that gave NO response in sensitive/smooth
were EASILY detectable in sensitive/extra/ deep. Bill you should accept
the findings and not question the ability of the testers or the
testing methods. The 4000 when used in sensitive/smooth has an
"ELECTRONIC HOLE" through which some nuggets including some very BIG
ones will fall. Unlike many forums including yours my forum is not ML
dealer run or controlled and is truly independent and I am sorry if
the testing results irk some ML dealers and promoters which is not
surprising as ML and the dealers are pushing the sensitive/smooth mode
on the 4000 very intensely. If people in the US want to get the best
results when the ground is suitable then they should try the settings
of mono lover as described on my forum with the gain adjusted
according to prevailing ground conditions and EM noise. At least then
they can be confident that they will not leave behind a good nugget
as they may if they use sensitive/smooth.
Best regards
Doug"

hey phoenix, sensitive/extra/ deep this is what i use with my 8" mono. it's good on small gold deep. i tryed using smooth and that and wasn't picking up as much as i am now. thanks for posting this
cheers
stoppsy

phoenix, do you know how long ago they posted this?

G'day Stopssy.
I think that info was put out in like late 2006. So it has been a known fact that Sen Smooth is not a large target, deep search mode. I think in the ML manual it says that you will loose depth and miss some latge deep targets in Sen Smooth.

colorado hi
i cant get in through that link you posted.
can you copy and paste the file here?
dave

G'day Dave
I can't copy and paste it. It is a PDF file and I cant copy anything. I may be able to E-mail you the PDF file if would like. I printed it out and use it in the fields if I run into a problem I wish they would put it in the manual.
