What Does It All Mean? The metal detection industry is full of jargon that may not mean much to someone new to the
hobby (or even veterans). That's why at Garrett, we strive to keep you informed of the latest technology, trends and features in the industry.
Why do we want to keep you updated? Because we feel strongly that supplying you with good information will empower you with the ability
to recognize that Garrett detectors shine where all others fall short. We want you to be successful. We want you to be a better treasure hunter.
We want you to be satisfied with your detector. So, whether you are buying your first detector or upgrading to a new one, you can rely on
Garrett to give you straightforward information that will lead you to the right detector for your treasure hunting needs.
A metal detector setting that detects all metal objects, no discrimination
Audio Threshold
The background audio level produced when no target is being detected - it is best to adjust the audio
threshold to the lowest audible level, and recommended the operator use headphones when treasure hunting
Audio Tone
The pitch or frequency of the sound made by a detector. The tone on the GTI 2500, 1500 and GTP 1350 detectors
can be adjusted on a treble to bass scale.
Cache
Larger deposits of treasure that
generally consist of money and valuable objects
Classifier:
A filtering device, typically found at the head of a sluice, which helps prevent rocks and other
large debris from falling into a gold pan.
Coin Shooting
Hunting for coins regardless of
location or era of coins targeted
Composite Digger
Trowel made of durable plastic that helps prevent coin damage during recovery. Ideal for
soft terrain
Control
Box
Contains the detector's main
circuitry, controls, speaker, batteries and microprocessor chip
TERM
EXPLANATION
DD
Searchcoil
A special configuration of the
transmit and receive coils to minimize the effects of ground minerals
DSP
(Digital Signal Processor)
A highly advanced computer chip
used in Garrett detectors and other sophisticated electronic equipment
Discrimination
The ability of a metal detector
to reject a target, such as a pull tab and foil or accept a target such as a
coin or jewelry based on its metallic composition
FastTrack (See Ground Balance)
Garrett's exclusive technology
that analyzes ground mineralization and adjusts to "cancel" its effects in a
matter of seconds
Frequency
The number of times per second the energy transmitted from a detector's coil changes direction (e.g. 7.0 kHz
= 7000 times per second) - higher frequencies are typically used to find targets such as gold nuggets, while lower
frequencies are best for general purpose hunting
Gold Pan
A bowl-shaped, shallow container that traps gold flakes
Gravity Trap™ Gold Pan
A patented gold pan made by Garrett which has 90 degree riffles to trap small gold
Ground Balance (See GroundTracking)
An adjustment made to "cancel" or ignore ground mineralization; may be done
manually or automatically
Ground Tracking
The ability of a metal detector
to continuously measure the ground's mineralization and automatically adjust
the detector's ground balance setting for optimum performance
GTA
(Graphic Target Analyzer)
Exclusive Garrett technology
that visually identifies a target's conductivity or ID and also shows the
discrimination pattern
GTI (Graphic Target Imaging)
Exclusive Garrett technology
that measures and displays a target's true size and depth
TERM
EXPLANATION
LCD (Liquid Crystal Display)
A graphical display that indicates target information, detector settings, etc...
Multiple Frequency
See Pulse Induction and Multiple Frequency article
Microprocessor
Computer chip that performs
digital functions that make many features such as Target ID and
Discrimination possible on today's Garrett detectors
Mono Searchcoil
Refers to searchcoils with one
ring where both transmitter and receiver antennae are located
Motion Mode
Refers to the setting where coil
motion is needed to detect targets
Notch
Discrimination
Targets above and below these
discrimination settings
Pinpoint
A mode of operation that allows
the operator to detemine the precise location of a target still in the ground
Pulse
Induction
Used primarily for heavily
mineralized environments such as the beach or the gold fields of Australia
and is found in many of today's specialty detectors (See also Multiple
Frequency)
PowerMaster
Exclusive Garrett feature that
increases the detector's ability to detect deeper and wider - up to 20
percent
Probe
A long screwdriver-like device made of brass used to penetrate the
ground and physically locate a detected target before digging it up
Prospecting
Hunting for valuable metals such
as gold
TERM
EXPLANATION
Relic Hunting
Hunting for targets with
historical value, such as old battlefield items or family heirlooms
Salt
Elimination
A detector's ability to
eliminate the interference of salt mineralization, which adversely affects
detection depth and target ID capabilities
ScanTrack
A unique Garrett feature that
automatically adjusts to the operator's scan speed to achieve optimum
performance
Searchcoil
Also referred to as the "coil",
the searchcoil is the flat, typically circular disk swept over the ground to
sense the presence of metal
Sensitivity
Synonymous with Depth, the
adjustment that determines how deep or small a target can be detected - the
higher the sensitivity, the greater the detection depth
Shaft
The adjustable stem that connects the control box and the searchcoil
TERM
EXPLANATION
Single Frequency
Offers greater potential depth
capabilities, better discrimination and enhanced target ID under most common
soil conditions where most treasure hunting occurs (See Multiple Frequency
article for more information).
Super Sluice™
Large 15" gold pan with 1/2" deep riffles. Traps small gold nuggets up to one ounce and larger in size
Surface Elimination
A detectors ability to ignore all targets located on or near the ground's surface, which is useful in heavy
trash areas
Surface Mount PC Board Technology
The latest trend in constructing
electronic circuit boards
Target
Any metallic item sensed by a detector
Target ID Cursor
A graphical indication of the target's probable identity (e.g. coin, gold, pull tab) based on its
electrical properties
TreasureTalk
Garrett's exclusive voice
function found only on the GTI 2500 that audibly announces various settings,
adjustments and target information continuously or on demand
Volume Control
The ability to adjust the loudness of the audible response produced by the detection of a target
