1. Introduction

Congratulations on purchasing Minelab’s Sovereign GT detector. The Sovereign GT metal
detector has been designed for general purpose detecting with features to suit the coin and
treasure hunter plus automatic ground balance for the gold fields.

The Sovereign GT detector uses Minelab’s unique

Broad Band Spectrum (BBS)

technology,

which enables the Sovereign GT to automatically transmit simultaneously in

multiple frequencies.

The benefits of multiple frequency technology are numerous and include increased depth,
greater sensitivity to non-ferrous metal objects, increased accuracy in discrimination and
increased accuracy in target identification. Add to this, Minelab’s automatic ground balance
and the Sovereign GT becomes a very versatile, all-purpose detector.

The Sovereign GT is designed to locate valuable metal objects in high trash areas and in
areas of extreme salt or mineralisation, conditions commonly encountered by gold and
treasure hunters around the world. When using a single or dual-frequency detector under
these conditions, a detectorist may experience a significant loss of detection depth and
discrimination accuracy. However, the Sovereign GT, with its BBS technology and automatic
ground balance, compensates for interference from these ground conditions and enables you
to penetrate deeply and discriminate accurately at full depth.

The Sovereign GT is simple to operate, having very few controls that require adjustment after
they have been set. The extremely advanced, yet simple-to-use, discrimination features
enable you to accurately select only the types of metal objects that you want to find and to
ignore those that you consider junk. The variable signal tone responses enable you to
accurately identify the object found before you recover it.

If you have any questions or comments regarding the Sovereign GT or any other Minelab
product, then please feel free to contact us via your local Authorised Minelab Dealer or write
to us direct.

Minelab Electronics wish you every success in your treasure hunting.

BBS Technology

When developing BBS technology, Minelab’s scientists first looked at
technology that was already available in the market and identified its
limitations in field use. Discussions with seasoned treasure hunters
from around the world identified a number of common problems
facing detector operators including :

• Loss of detection depth in mineralised ground.

• Inaccurate target identification beyond 5 or 6 inches.

• Inability to detect good targets in close proximity to iron trash.

• Erratic operation when searching salt-water beaches.

Most detectors on the market operate on a single (or dual)
frequency. Although this technology has served the industry well
for years, Minelab’s scientists found that a frequency that worked
well in one area would often offer only marginal performance
when used in another location. Ground mineralization, trash
content, and target size all had an effect on how well a
detector transmitting a single frequency would operate.

The BBS circuit automatically transmits a number of
frequencies simultaneously; a feature which is unique to
Minelab metal detectors. Ranging from 1.5 to 25.5 kHz in

1.5 kHz increments, the signal received from the coil is
analysed and information is relayed to the operator via
the speaker, headphone, and meter (if attached).
Through the use of so many frequencies, the
Sovereign GT

is designed to locate and
accurately identify valuable targets in variable
ground and high trash areas.

Essentially, when using a

Sovereign GT

with BBS technology, it is like swinging a

number of single-frequency detectors at
the same time. Because BBS operates in
a number of frequencies that no other
detector does, BBS detectors such
as the

Sovereign GT

can find a
broad range of objects that no
other individual detector
has the ability to find.

The Sovereign GT combines Minelab’s unique multiple frequency BBS technology with
automatic ground balance and improved signal processing to give:

•

Greater detecting depth.

•

Consistent sensitivity over a wide range of targets.

•

Good target identification & discrimination of trash.

•

Operation in mineralised ground.

Therefore, the treasure hunter is more likely to detect targets normally missed by other
detectors.

One of the major overall benefits of BBS technology is that although it automatically
operates at so many frequencies, all at the same time, it is actually easier to use than most
of its competitors. Because it is microprocessor controlled, all you need do is set the
threshold, discrimination and volume, and the rest is done for you automatically.

Most coin detectors do not work well on saltwater beaches, and Pulse Induction detectors
designed for beach use have very little or no Discrimination ability. The Sovereign GT not only
performs flawlessly on a saltwater beach, whilst discriminating targets with amazing
accuracy, it also has a true ground balancing all-metal mode that allows operators to find very
low conductive items such as gold nuggets, and ferrous based relics in mineralised soils.

A BBS detector will penetrate deeply, discriminate accurately and can be used in a variety of
ground conditions. The bottom line is that when using a Minelab detector such as the
Sovereign GT with its BBS technology, you will find good targets, more often.
