Coils
Selecting the correct coil size and configuration will optimise your GPX 6000's
performance in a range of detecting scenarios� Understanding when to use each coil
will increase the productivity of your detecting sessions�
The GPX 6000™ is supplied with two coils — a GPX 11™, plus either a GPX 14™ or GPX 17™ coil depending on your region�
GPX 11™ Mono
The 11‑inch round monoloop coil is a great general‑purpose coil that is recommended for most detecting conditions� It is
a good all‑rounder that has excellent depth and sensitivity, is very sensitive to smaller nuggets, and is easy to manoeuvre
around obstacles�
GPX 17™ Mono
The 17 × 13‑inch elliptical monoloop coil is the top performer when searching for larger deep nuggets in less conductive
(salty) ground� It can effectively cover large areas of ground quickly and efficiently�
GPX 14™ Double‑D
The 14‑inch round Double‑D coil excels in the following conditions:
` Where there are high levels of electromagnetic interference�
` In very conductive (salty) soils�
It can operate successfully in conditions that render monoloop coils unusable� Conductive (salty) soils commonly occur when
soil contains salt, and is often most noticeable after rain when ground salt is dissolved in water�
Use of a Double‑D coil is only recommended if good results cannot be achieved using a monoloop (Mono) coil�
When a Double‑D coil is connected, there are two Double‑D modes available to choose from� It is best to set the Double‑D
mode based on the source of noise� For more information, see
the Factory Preset Double‑D mode (EMI Cancel) will be adequate when first getting started�
Changing the Coil
START `
1. Turn the detector off.
2. Unplug and remove the coil.
3. Attach and plug‑in the new coil.
4. Turn the detector on.
5. If using a Double‑D coil,
select a Double‑D mode.
