The Ultimate Metal Detecting Glossary

Whether you’re new to the world of metal detecting or have been in the game for so long that the latest slang may as well be a foreign language – we’ve got you covered here.

Delving into the thoughts and shared perceptions of the metal detecting community, this is the ultimate metal detecting glossary to bury the jargon deep underground.

To get the most accurate and up to date use of metal detecting vocabulary (all PG, of course!) we asked detectorists on social media about the language they use when metal detecting. Read ahead for the final list…

TitleDescription
All Metal
a common detecting mode which represents the whole frequency spectrum. 
Ants

A method of referring to seemingly endless sea of detectorists descending on the fields at rallies and events.

ArchieAn Archaeologist
BeercaniteAluminium blobs, often found on the beach.
BluetoothWhy do we need to know about Bluetooth in metal detecting? Good question. You may have a detector with wireless audio, if so, this is likely to be the method in which the audio is sent to your headphones from the detector.
Bull's HeadA George III coin. Aptly named due to the size of his head resembling that of a bull.
BucketlisterA find that you have been waiting for, for some time. Something from your detecting ‘bucket list’
CanslawA shredded can, most likely destroyed from the farming plough. 
ChatterWhen a detector is giving lots of erratic signals, commonly from ground noise. This can be addressed by conducting a ground balance or by lowering the sensitivity of the machine. 
ChoppyWhen the detector finds a signal, but discriminates it out.
Clipping or ClippedThis is the process used of trimming the outside edges of hammered coins so that the edges may be re-used to form new coins. It’s a cheeky idea which would yield more money if enough were clipped.
Coin BallWhen the mud around a coin has formed a sphere when you remove it from the ground
Coin SpillFinding a large amount of coins in the same area. Very common in ancient burials, or beach locations where someone may have dropped a lot of change.
Clod / Plug
A large clump of earth which has been removed to help located the find. It’s desired that the piece can be replaced in as few pieces as possible.
CMD
Crawfords Metal Detectors ‘an excellent shop to buy products from with an excellent service’ – Thank you Lawrence M – He is a smart fellow.
Conductivity
The degree to which an object or material conducts electricity.
Dirt Fishing
A slang term for metal detecting – fishing through the dirt (sometimes used as a method of referring to mudlarking too). 
Discrimination
The process of eliminating/omitting specific signals. This is important if you’re trying to find something specific. 
Eddy Currents
Caused by the magnetic flux, induced within the targets. Producing and detecting eddy currents is the basis of detecting technology. 
Eyes Only
A surface find spotted prior to the detector passing over it!
Ferrous
Containing or composed of Iron
Field of Dream
A site which provides phenomenal results, most likely an ancient settlement or place of significance.
Find
Any item which is found!
Fibula
A piece of a Roman styled brooch. These are beautiful to find. 
Field Liaison Officer (FLO)

The person you report your significant finds to. There is a FLO for every county in the UK. You can find your nearest FLO on the PAS website - Finds Website

FeCo
A method of measuring a targets Iron composition (Fe) and it’s Conductivity (Co) simultaneously. This is seen on machines such as the CTX3030 and the Manticore.
Ground Balance
the process of adapting or calibrating a metal detector to the conditions of a particular environment. It ‘balances’ the machine to the ground, think of this as to tare a set of kitchen scales.
Grotts / Grottys
Old coins which are in poor or, ‘grotty’ condition. 
Halo Effect
The leeching affect of a target to it’s surrounding area with creates adjustments to the environment. 
Hammered
A coin which has been fashion by the process of hammering metal within a die to create the desired indentations/design. These are great to find.
Hawker or Night Hawking
Night hawking’, is the process of detecting in fields at night, most likely without permission. This is illegal and does not benefit the reputation of our hobby. 8-(
History Wand
An affectionate name for a metal detector.
Hoard
A hoard is a large amount of treasure found in the same location. A group of coins is classed as a hoard when there are; two or more precious metal (more than 10% content of gold or silver for example) coins, or three base metal (bronze, copper) coins found in the same location.
Honey Hole
A single spot/hole that produces great finds
Hot Rocks
Pieces of rock or earth which provide highly mineralised or conductive signals.
Iron BiasThis is a process employed by a detector to try and reduce the effect of signals received from iron when detecting. Setting the iron bias higher reduces the iron signals displayed by the detector, but can result in more inaccurate detecting.
LatencyThe speed at which data transfers – relevant to audio signals in metal detectors – the quicker, the better! Try to aim for Bluetooth 5.0 if possible as this would meet ‘low latency’ standards. 
Low and SlowPractical advice on how to swing your coil for best results. Swing it close to the ground in a slow motion. 
MaskingWhen the detector is picking up Iron and not the target it is masking. The new Minelab Manticore is brilliant at avoiding masking and can signify this well with its 2D display. 
Moo TubeA small tube, which would have contained ointment used on Cows, which is commonly found in pasture fields.  
Multi-FrequencyA metal detector which utilises multiple frequencies to provide information to its user.
Multi-IQMulti-IQ is the world famous Minelab, multi-frequency method of producing and processing detecting information. It’s highly intelligent, and performs particularly well in difficult conditions, such as the beach.
MultiIQ+As above, but with even more processing power. Currently only available on the Minelab Manticore.
NickedWhen someone has slightly damaged a find when digging or removing the target from the ground.
Non-FerrousA metal containing no traces of Iron or steel.
OverspillWhen returning the removed soil from a target dig, you leave excess soil surrounding the hole. 
Partifact
a metal object that has no known identity – a part of an artefact. 
PAS - Portable Antiquities Scheme 

PAS is a scheme managed by the British Museum which is responsible for compiling and maintaining a database for all significant finds and treasures discovered throughout the UK. More information on PAS

PermissionThis is the verbal or written permission which is provided by a landowner or responsible party which allows metal detecting to occur. ALWAYS ensure you have permission to detect in the location you are in, or you risk breaking the law and also putting the hobby and other detectorists into disrepute.
Purse BarA metal bar, commonly worn on the waist which supported a purse.
Pin PointerA hand-held detector which is designed for precise target identification and therefore perfect for the final moments of locating a signal. 
Pontiac FirebirdA little joke here from BBC series, The Detectorists. It’s a small toy car the main characters find and which can be common, fun little finds! 
ProbeAnother name for a pin pointer.
Recovery SpeedThe speed at which a detector can detect. If multiple targets lie in close proximity, a slow recovery speed may miss them, or read them as one long target, whereas a fast recovery speed will illustrate the definition or, space between the targets. 
A RomanAn artefact from the Roman civilisation commonly used to refer to coins. 
SensitivityDescribes how sensitive the metal detector is to its environment. You can think about this as how much of the environment the detector is reporting. 
ScoopingA warm nick name for beach detecting.
A SunbatherAnother name for a ‘Surface Find’.
A 'Shiny'commonly gold as it doesn’t tarnish, but a coin or object that comes out of the ground in a shiny condition. 
A 'Shotty'A Shot Gun cap - very common on farmland!
Surface Findan item which lays upon the surface and requires no digging to acquire.
TargetRefers to the item which has been located by the detector, but not yet unearthed/discovered.
Target IDThe numbers received by a detector which give indication as to the identity of the target.
Target ToneThe sound/tone produced when a signal is encountered. On more sophisticated machines the tones can be altered to the user’s taste. 
ToastedA coin with no indentations/embossing remaining. 
Viccyan abbreviated term for, ‘Victorian’, related to any artefact from this time period – ‘a viccy penny’ = a Victorian penny.
WaterproofIt’s an obvious one, but ensure you are aware of how waterproof your equipment is. Some detectors have a waterproof search head and some, such as the Equinox 800 and Manticore can be fully submerged, for river, beach and sea detecting.
