THE MINELAB EXPLORER II

INTRODUCTION

Full Band Spectrum (FBS)

When developing Full Band Spectrum (FBS) technology, Minelab’s

scientists looked at improving the already successful Broad Band

Spectrum (BBS) technology used in previous Minelab detectors.

Discussions with seasoned treasure hunters from around the

world identified a number of possible enhancements for

operators. The improvements to the Explorer II detectors include:

• increased detection depth;

• accurate identification of targets to greater depth;

• enhanced detection of desired targets amidst iron trash;

• adjustments to improve operation for searching salt-water

beaches.

Most detectors on the market

operate on a single (or dual)

frequency, ranging from 1 to 70

kilohertz (kHz). 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

mineralisation, trash content, and

target size all had an effect on how

effective a detector transmitting a single frequency would operate.

Full Band Spectrum technology combines Minelab’s existing

multiple frequency BBS technology with a powerful new

microprocessor to give:

• greater detecting depth;

• consistent sensitivity over a wide range of targets;

• less interference from electromagnetic sources;

• more accurate identification of target characteristics.

MINELAB’S UNIQUE TECHNOLOGY

Discrimination

Discrimination is the ability of a

metal detector to identify the user’s

desired target (e.g. jewelry) and

eliminate signals from undesirable

material (e.g. nails).

The Explorer II can be programmed

in a number of ways to discriminate

against unwanted targets in

different types of ground.
