Where I hunt and do so well are old Railway Stations, Old Docks, and
Old Piers. Let me ask
you what do all three sites have in common? IRON TRASH The Excalibur
and Sovereign share
some common items and one is the Iron Mask Mode which is now hard wired
in the circuit. The
way this machine treats iron is different then any other machine on
the market. All other machine
treats it as an active target on equal ground with a gold ring or a
silver dime. The normal VLF
would see the iron and the dime and average the two together to get
a response providing it hits
both targets at the same time. If the iron has leached or is bigger
or there is more iron then dime...
then the dime signal is lost all together. Here the BBS Technology
looks at the iron signature and
separates it almost like it does a mineral signature except this is
an active target it then looks for any
other signature if finds any signal NON-ferrous it will drop the iron
signature and report only
Non-ferrous signatures. If it does not find a Non-ferrous signature
it will provide a iron (negative)
tone and threshold drop. Now it does this all in a Nano-sec thats 1
sec times 10 to the -9th
power... now I don't know about you but that's quick. Now for the wider
response signal... it's true
target closer to the surface provide a wider response then the normal
VLF unit and at 4" it shorter,
and at 8" its shorter in duration and at 12" it's real quick and so
on and so on... The only
advantage the BBS Technology has in Non-ferrous trash area is the coil
and the detection path...
and the required slow motion of the machine... which allows you to
twist and turn the machine
weave thru partial signal. Try hunting in All Metal and when you hit
a target turn it to discrimination
and change Line of attack to separate out the targets if it truly trash
no matter what angle you
approach it will still be trash. But if it's a coin with a trash it
maybe possible to separate the trash
from the coin because of the wave pattern.
One last thing, and this is something else that the BBS bring to the
table it gives you pulse
depth with VLF features through the way it interprets the ground mineralization
signature. Now the
normal VLF unit uses ground balance to raise and lower the filters
against a Zero background an a
positive Mineral Feedback. That is why you raise and lower the coil
and make adjustments or if
you are lucky enough to have a Microprocessor ground balance, the machine
takes a air sample and a
ground sample and change the filtering to eliminate the ground signal.
At no time is it looking at the
signature of the ground just the amplitude of the signal and then raises
the filter to eliminate this
background signature. Now let me ask you something what happens when
you filter something?
(I'll comeback to this, think on it a while) Well , the ground balance
process is fooling the
machine into thinking it is hunting in air and to interpret targets
as if it is hunting in air, or may we say
bench testing the unit. Beyond that the ground signal is nothing in
the eyes of the VLF machine.
(answer to your question anytime I filter something I lose something
of what I'm hunting for or in
simple terms I lose depth) That is why a Pulse machine go so deep it
does not concern itself with
mineralization it's not in the equation but then again a Pulse Machine
sees all and cannot find certain
types of metal. Also the VLF machine since is dealing only with amplitude
of ground signal it is not
concern with signature of the mineral which all minerals and combination
of minerals have. The
VLF cannot see or compensate for the masking effect of the ground signature
to bend or change the target signature. Here the BBS rules... BAR NONE...
Here the BBS sees the target signature and takes it into the equation and
does not filter the ground resulting in greater depth in heavier
mineralized environments. It also does not fool itself into thinking
it is on a bench an a target at 1" has the same reading as a target at
10" like it is in the air just a weaker signal. The ground signature is
not compensated for so a dime reads as a nickel and a nickel like a nail
and so on.... In this same
ground with BBS a dime reads a dime a nickel reads as a nickel and
the nail is a nail.... The more
mineralize the effect the more you will see the results... also even
though you may be hunting in a
low mineralization area at surface you will see little change and at
1" maybe a number maybe not
but at 10" or 12" it has a accumulative effect and a dime may now reads
as a zinc penny or a
pull tab.... But with BBS with will still read as a dime.
It's not one factor but all the factor combined....
