Field
Ideal for detecting in historical fields for the
widest range of target sizes.
Field Mode is for searching open pasture, cropped or ploughed fields and
historically occupied sites� These environments generally contain ferrous
trash and coke from previous human occupation� In highly infested sites,
Field Mode is well suited for rejecting coke and detecting hammered coins
and ancient artefacts amongst the iron trash�
Field Profile 1: Coins and Artefacts
Field 1 is for general hunting with high trash rejection� This assists in
locating desired targets more easily� The default discrimination pattern is
set to reject Target IDs 1 to 4 (most coke signals)�
When non‑ferrous targets are surrounded by ferrous trash, the Target ID
can be shifted down into the ferrous region� Tone Breaks in both Park and
Field Modes are set to –4 to ensure no non‑ferrous items are missed�
Using 10 kHz in Field 1 means it is most suited for general detecting and
coin hunting�
Field Profile 2: Fine Coins and Artefacts
Field 2 suits locations with high target and trash densities, including
ferrous trash� It will better detect large coins on their edge or at greater
depth� The default discrimination pattern is set to reject Target IDs 1 to 4
(most coke signals)�
Target Tone is set to All Tones to enhance audio identification and Recovery
Speed is faster� Field 2 uses 15 kHz as a default, to maximise performance
in ferrous trash infested locations�
CONTENTS
Field Detecting Hotspots
When it comes to detecting for historical
items, you will want to find old inhabited sites
that may have long disappeared from view�
Research is a great way to find out where
old sites may have existed from old texts,
maps, and articles� This method of site
selection can pay off and yield wonderful
results� Freshly ploughed fields are also
very good detecting locations, as targets
that were deep may have been churned to
the surface during ploughing�
Difficult Field Areas — Coke
Coke is the charcoal and carbon by‑product
of burnt coal, and is prevalent around
historically populated areas�
Generally coke has a Target ID of 1 or 2,
but can be as high as 4� For this reason it
is rejected by default in Field Mode� Note,
this could result in some small non‑ferrous
targets being missed�
Rejected Target IDs 1 and 2 in the
discrimination pattern for Field
Mode Search Profiles�
