THE MINELAB EXPLORER II

!
MINELAB’S UNIQUE TECHNOLOGY
The Full Band Spectrum (FBS) circuit automatically transmits 28
frequencies simultaneously. This increased frequency range means
that the signal received from the detector coil is analyzed from a
wide range of responses. This information is relayed to the operator
via the speaker or headphones and the control panel’s liquid crystal
display as an audio or visual target response.
Put simply, Minelab’s unique FBS technology means deep, sensitive,
accurate detecting.
Ground Compensation
The Explorer II uses a sophisticated approach to the elimination of
ground mineralisation. It uses advanced digital filtering to eliminate
the influence of ground signals.

Operating Frequencies
A metal detector’s
electromagnetic operating
frequencies are measured in
kiloHertz (kHz).
Low signal frequencies
(e.g. 1.5 kHz) penetrate deepest,
but sensitivity to smaller targets
is low.
On the other hand, higher
frequencies have a more
shallow depth of penetration
but high sensitivity to small
targets.
The Explorer II’s multiple-
frequency operation provides
the advantage of both.
