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,
though it can go as high as 4� For this
reason it is rejected by default in Field
Mode� Note that this could result in some
small non-ferrous targets being missed�
Field 1 Multi-IQ, even with Target IDs 1 to 4
accepted, will reject more coke more than
Field 2 using Multi-IQ�
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�
With Frequency set to Multi, Field Mode will be the most sensitive to the widest range of targets and more accurately
identify objects at the limits of detection depth, compared to all single frequency options�
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)�
The first Tone Break is set so that Target IDs 1 to 4
will produce the same low tone as ferrous targets�
Field 1 Multi-IQ processes a lower frequency weighted
multi-frequency signal, as well as using algorithms that
maximise ground balancing for soil, to achieve the best
signal to noise ratio� Hence being 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 small
hammered 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 (At) to enhance audio
identification and Recovery Speed is faster� The first Tone
Break has been set so that Target IDs 1 to 4 produce
the same low tone as ferrous targets� Field 2 Multi-IQ
processes a higher frequency weighted multi-frequency
signal while ground balancing for soil�
