THE MINELAB EXPLORER II

INTRODUCTION

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.

You are now ready to proceed to Chapter 2: Assembly.

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.
