SEARCHCOILS  
The Infinium LS comes standard with a 10" x  
14" Power DD searchcoil. The DD coil configuration  
couples with the API technology of the Infinium LS  
make it the most powerful detector in mineralized soil.  
In areas where the ground is low in mineraliza-  
tion, the optional 10" x 14" mono searchcoil is recom-  
mended. In these ground conditions, the mono coil  
will outperform the Power DD.  
For smaller targets in low mineralized soil,  
choose the optional 8" mono searchcoil. It provides  
easier maneuverability than the 10" x 14" mono.  
For underwater hunting, choose your searchcoil  
using the same criteria as land hunting. Consider the  
level or mineralization of the water and/or the soil  
at the bottom of the body of water. For example, in  
saltwater, the Power DD is the best choice. In fresh-  
water, however, the mono searchcoils will perform  
better. Another criteria would be the size of the target.  
Generally speaking, the smaller the target, the smaller  
the searchcoil should be.

CONTROLꢁFUNCTIONS  
Figure 15  
Power  
Used to turn on the detector and to choose slow,  
lock or fast Automatic Ground Track. A battery check  
occurs automatically each time the power is switched  
on. (Figure 15.)  
AudioꢁThresholdꢁAdjustment  
Used to set the base audio level according to an  
individual's hearing requirements. The Threshold  
Adjustment may also be used to help mask outside  
noise. Typically, the sound is set no louder than  
necessary; just above silent is recommended. (Figure

1ꢂ  
 
DiscriminationꢁAdjustment  
Used to set the desired level of discrimination.  
(Figure 15.)  
The following procedure shows how easy it is to  
operate the Infinium LS.  
BASICꢁOPERATINGꢁINSTRUCTIONS  
1.ꢁꢁTurnꢁOn/BatteryꢁTest:  
Turn the detector on and note the results of the  
battery test represented by a range of one to four  
beeps. Four beeps indicate the batteries are full. One  
beep indicates they need to be replaced within one to  
two hours. However, because of internal voltage regu-  
lation circuitry, the detector will maintain total operat-  
ing power and performance until the batteries are fully  
depleted.  
Scan a metal object to confirm detection. If the  
detector fails to operate, verify that the battery pack  
and batteries are aligned properly.  
ꢀ.ꢁꢁSelectingꢁAutomaticꢁGroundꢁTrackꢁSetting:  
Knowing the conditions of your search area will  
help you choose the Automatic Ground Track setting  
that will best suit your needs.  
Initially select the Lock position using the rotary  
power switch. Operating in the Lock position is  
1ꢃ  
 
recommended for maximum detection depth unless:  
A.The detector is not properly ground balanced, or  
B.You are hunting in changing ground mineralization  
conditions that require continuous ground tracking.  
Improper ground balance or changing ground  
mineralization are identified by erratic audio signals  
caused by the ground. If you experience these sig-  
nals, you will need to switch the rotary dial to fast or  
slow. It is recommended that you ground balance the  
machine before continuing.  
To ground balance the detector, turn the Automatic  
Ground Track switch to either fast or slow, and bob  
the coil up and down approximately one to six inches  
above the ground. When the detector's audio signal  
smooths out, move the Automatic Ground Track rotary  
switch to lock and the unit will lock the ground track  
setting at that value.  
If erratic audio signals continue, you may need to  
turn the Automatic Ground Track to slow or fast and  
hunt in one of those modes.  
Use Slow when:  
A. Operating over slowly changing ground  
mineralization, or  
B. When small ground balancing adjustments are  
needed.  
1ꢄ  
 
Use Fast when:  
A. Hunting over extreme or quickly changing ground  
mineralization, or  
B. When large ground balancing adjustments are  
needed.  
Improper ground balance will degrade detection  
depth and audio stability. It should not be necessary  
to reground-balance every time you turn the machine  
on. It will continue to operate with the same ground-  
balance level before the machine was turned off.  
In the rare event that extreme ground conditions  
continue to produce audio signals, increase discrimi-  
nation in small increments until the detector becomes  
stable. To ensure maximum possible detection depth,  
only increase discrimination enough to achieve detec-  
tor stability (this should never exceed the 3 setting on  
the dial).  
ꢂ.ꢁꢁSettingꢁThreshold:  
Set the base audio level according to your individ-  
ual hearing requirements. The Threshold Adjustment  
may also be used to help mask outside noise.  
Typically, the sound is set no louder than necessary;  
just above silent is recommended.  
ꢃ.ꢁꢁSettingꢁDiscrimination:  
Set the Discrimination control to zero or a low  
level until you are familiar with the conditions of  
1ꢅ  
 
your search area and determine the kinds of metal  
items you want eliminated from detection. With zero  
discrimination, you will achieve maximum detection  
depth and will detect all metals including foil and pull-  
tabs, but you won't miss any desirable targets. Once  
you are familiar with the hunting area, then re-adjust  
the discrimination setting to a level that will eliminate  
unwanted items.  
Be aware that high concentrations of saltwater may  
require increasing the Discrimination up to a value of  
three or less (see tips on Searching Shorelines and  
Shallow Surf on page 25).  
ꢄ.ꢁBenchꢁTestingꢁandꢁUnderstandingꢁ  
ꢁ AudioꢁSignals:  
Bench testing is recommended to familiarize your-  
self with the detection capabilities and audio respons-  
es of the detector. This will help you determine if  
a target is treasure or trash. Since Pulse Induction  
machines only give audible clues to the identity of  
detected targets, it's important to learn these different  
signals.  
Tests should be performed (Figure 16) with the  
searchcoil perpendicular to a bench, floor or other  
non-metallic surface and several feet away from any  
large metallic object. Pass various metallic targets  
from side-to-side across the bottom of the searchcoil  
at a distance of about three inches. Listen carefully  
1ꢆ  
 
to the audio tones,  
noting which targets  
produce high and low  
tones and how the tar-  
get response changes  
with discrimination.  
As a general rule,  
poor conductors  
(small nuggets, most  
rings, pull-tabs, nick-  
els, etc.) should pro-  
Figure 16  
duce a high tone followed by a low-tone echo. Good  
conductors such as large nuggets, pennies, dimes,  
quarters, etc. should produce a low tone followed by  
a high-tone echo. In addition, most iron will produce a  
low tone followed by a high-tone echo, since to a PI  
machine, iron behaves like a good conductor.  
ꢅ.ꢁꢁSearchcoilꢁScanningꢁTechnique:  
Methodically sweep the searchcoil from side to side  
keeping it at a constant height of one to two inches  
above the ground. Restrict your sweeping speed  
to about 1/2 to two feet per second. Overlap each  
sweep by about 1/4 the diameter of the searchcoil.  
Try to scan in a straight line (not a wide arc); it helps  
keep the searchcoil level, reduces the likelihood of  
lifting the searchcoil at the end of each sweep and  
ensures the overlap sweeps remain uniform.  
1ꢇ  
 
ꢆ.ꢁꢁReverseꢁDiscriminationꢁTechnique:  
When a target has been discovered while operating  
at minimum discrimination, you may use the reverse  
discrimination technique to help determine possible  
target identification.  
A.Once a target is found, increase discrimination to  
maximum level (Iron Check).  
B.If the target still produces a substantial signal  
there is a good chance it is iron. If the target has  
disappeared or produces only a faint signal then it's  
probably a desirable target and not iron. Be aware,  
however, that some small iron may behave like a  
desirable target, and some desirable targets such as  
large nuggets and coins may behave like iron.  
C.As with all PI detectors, eliminating the detection of  
iron is difficult if not impossible; however, the reverse  
discrimination technique is effective at identifying  
most iron. In addition, attaching a magnet to the  
inside of your digging tool can help separate bits of  
iron and other debris from your treasure finds.  
D.Finally, it is important to remember that any detec-  
tion signal, no matter how loud or faint,  
represents the sound of metal and its source should  
always be determined.  
1ꢈ  
 
ꢇ.ꢁꢁPinpointingꢁTips  
Whenever your detector locates a target, locating  
it precisely will enable you to recover it by digging  
the smallest hole possible. This is accomplished by  
pinpointing. Note that pinpointing with a DD searchcoil  
is somewhat different than pinpointing with a mono  
searchcoil. The instructions for each are below.  
PinpointingꢁwithꢁPowerꢁDDꢁSearchcoil  
The Power DD coil has a narrow detection field  
pattern that runs front-to-back underneath the center  
section of the coil, so always detect by sweeping the  
coil in a side-to-side motion.  
First, slowly scan the searchcoil from side-to-side  
over the target area, noting the location where the  
loudest signal occurs. Once the area with the loudest  
signal has been identified, position yourself 90° from  
the target area and again scan side-to-side to pinpoint  
the target's exact location.  
For targets on or close to the surface, start behind  
the target's suspected location and scan the area  
using short side-to-side sweeps while moving forward  
until the target is exactly pinpointed underneath the  
tip of the coil.  
ꢀ0  
 
PinpointingꢁwithꢁMonoꢁSearchcoils  
First, slowly scan the searchcoil from side-to-side  
over the target area, noting the location where the  
loudest signal occurs. Then draw an imaginary "X" on  
the ground by scanning the searchcoil front-to-back  
and again noting the location of the loudest signal.  
The center of the "X" is the location of your target.  
Note: the Infinium LS is a motion-mode-only  
detector; the searchcoil must be moving slightly in  
order to maintain detection sound.  
ꢈ.ꢁꢁAdjustingꢁFrequency  
You can subtly adjust the operating frequency to  
reduce interference caused by other detectors or  
power lines if needed. To adjust frequency:  
Turn the Threshold dial beyond “MAX” to “Freq.  
Adjust” and you’ll notice that the audio threshold was  
increasing and then abruptly dropped back to a lower  
level. The detector is now in a "Frequency Adjustment  
Mode".  
You can now adjust the operating frequency using  
the Discrimination knob. Incrementally adjust the  
Discrimination knob, pausing after each adjustment  
to listen, until you obtain minimum interference. Note  
that there are 32 different frequencies to choose from  
so turn the dial in very small steps.  
ꢀ1  
 
Once you obtain the quietest frequency, return  
the Threshold knob to your normal setting and the  
frequency will lock at the chosen value. You can then  
return the Discrimination knob back to your normal  
setting. When the detector is turned OFF/ON, it will  
always return to its factory default operating frequency.  
HUNTINGꢁAPPLICATIONS  
Garrett's Infinium LS has been designed to hunt  
everywhere, especially in mineralized areas, where the  
performance of conventional detectors suffers. A few  
examples of these are:  
• Prospecting—gold is usually found in highly  
mineralized soil.  
• Relic hunting—most U.S. Civil War battles took  
place in mineralized soil.  
• Beach/diving—any salt water is considered a  
mineralized environment (Underwater headphones  
are required for diving application. See accessories  
on page 30.)  
• Mine detecting—environmental-proof package is  
rugged, and will operate anywhere.  
ꢀꢀ  
 
SEARCHꢁANDꢁRECOVERYꢁTIPS  
Doꢁresearch.  
The first rule of successful treasure hunting,  
whether on land or in the sea is to do your homework.  
Learn as much as you can about the areas you wish  
to search, the kind of treasure you want to find and  
the best ways to recover it. The better prepared you  
are the greater your chances for success.  
The following books by Charles Garrett, which  
are available from Garrett Metal Detectors or your  
authorized dealer, offer invaluable research advice  
and detailed information on search and recovery  
techniques for hobbyists: How to Search Sand and  
Surf; Treasure Hunting for Fun and Profit; Ghost Town  
Treasures; and Treasure Caches Can Be Found.  
Studyꢁsurfꢁandꢁweatherꢁpatterns.  
Pay attention to storm, wind and tide activity.  
Treasures from deepwater vaults are often transferred  
to shallower locations like tidal pools and water-filled  
depressions near the shoreline.  
A beach considered unproductive can suddenly  
yield riches. Heavy storm waves often unearth  
treasures like rings caught in exposed rock and  
gravel areas.  
ꢀꢂ  
 
Useꢁtheꢁrightꢁrecoveryꢁtools.  
Use the right tool for the job and you'll recover trea-  
sure in no time. Knowing what you're digging for and  
the kind of surface you're digging into will help you  
choose the proper digging tool.  
Double-checkꢁyourꢁholes.  
After you dig a target, re-scan the hole to make  
sure you have retrieved everything in and around it;  
corroded and coral-encrusted desirable items can be  
easily mistaken for undesirable ones.  
Underwaterꢁsearches  
The Infinium LS can locate both ferrous and non-  
ferrous metals concealed within and below aquatic  
growth, bottom soil and rocks, wood and other non-  
metallic materials. Large items such as boats, motors  
and safes can be located several feet below the  
searchcoil. (Underwater headphones are required for  
underwater searches. See accessories on page 30.)  
UnderwaterꢁSafetyꢁTips  
1. To avoid acid damage you should install high-  
quality batteries such as alkaline or nickel-metal-  
hydride (NiMh) and always remove them prior to  
storing the detector.  
2. If the battery compartment becomes flooded,  
ꢀꢃ  
 
remove the batteries immediately, rinse the com-  
partment with fresh water and allow to air dry. The  
electronics compartment is factory sealed and should  
never be opened.  
3. Before diving always examine the searchcoil and  
headphone connectors, the battery cap and verify the  
battery strength.  
4. Dive with extreme caution. Observe safety practic-  
es to lessen the risk of becoming entangled with the  
headphones or coil cables. Ensure that the underwa-  
ter headphones' vent holes are open prior to diving.  
5. When using the hip mount configuration, ensure  
that the belt will not interfere with diving equipment  
removal in the event of an emergency.  
SearchingꢁShorelineꢁandꢁShallowꢁSurf  
The Infinium LS is a highly sensitive detector and  
has the capability to detect metals with only the slight-  
est conductivity. As a result, the Infinium LS may  
also detect high concentrations of saltwater due to  
its conductivity. This effect is most noticeable when  
operating at the sea's shoreline and in the shallow  
surf where the searchcoil is continually encountering  
passing waves.  
ꢀꢄ  
 
Increase the Discrimination setting only as needed  
in order to reduce saltwater detection. Typically, a  
setting of three or less is sufficient. Do not be con-  
cerned about missing targets due to the increased  
Discrimination. Rather, the stable operation achieved  
with this slight increase in Discrimination will ensure  
the best possible target detection for this saltwater  
environment.  
Landꢁsearches  
When searching near wire fences, metal buildings,  
etc., make sure that you scan the searchcoil paral-  
lel to the structure. This will minimize the interfering  
responses caused by the metal structure.  
Prospecting  
Gold and other precious metals can be found in  
various forms with the Infinium LS. You will most likely  
be searching for nuggets, but gold can also be found  
as lode or hard rock deposits in a vein, usually mixed  
with other minerals. The Infinium LS can also be used  
to locate placer deposits in streams or dry sand.  
Since working vein or lode gold can require  
expensive tools or technology and placer deposits  
must be panned for recovery, these forms are some-  
times unsatisfactory for metal detector hobbyists.  
Recovering a nugget, however, is as simple as putting  
it in a treasure pouch.  
ꢀꢅ  
 
Gold is generally found in rock formations along  
with a great many other conductive/ferrous minerals.  
A high quality detector, such as the Infinium LS with  
its Advanced Pulse Induction technology that cancels  
out mineralization, can be used to find this gold or  
any other precious metal.  
It must be emphasized that the Infinium LS or any  
other quality detector is usually operated with zero  
discrimination and very precise ground balance if gold  
is to be found. This is particularly important when  
searching for tiny gold nuggets. Furthermore, when  
prospecting, all targets must be located and carefully  
inspected. It is only in this manner that you can be  
successful in using a metal detector to discover pre-  
cious metal nuggets and ores.  
Hard work, patience and research are three of the  
keys to success in electronic prospecting. Research  
is important because it is vital that gold always be  
sought in areas where it is known to exist.  
Hot rocks are a problem for any electronic pros-  
pector, whether veteran or weekend adventurer. A  
"hot rock" can be described as a concentration of  
iron mineral that causes a detector to recognize it  
as metal when the instrument is operating with zero  
discrimination. Fortunately, the advanced technology  
of the Infinium LS allows it to ignore nearly all hot  
rocks; only the most extreme hot rocks will produce a  
response.  
ꢀꢆ  
 
DETECTORꢁMAINTENANCE  
Your Garrett detector is a sensitive electronic  
instrument. It is built to withstand rugged treatment in  
the outdoors. Use the Infinium LS to the fullest extent  
possible, and never feel that you have to baby it. Yet,  
always handle it with reasonable care.  
Try to avoid temperature extremes as much as  
possible, such as storing the detector in an automo-  
bile trunk during hot summer months or outdoors in  
sub-freezing weather.  
Keep your detector clean. Always wipe the housing  
after use, and wash the coil when necessary. Protect  
your detector from dust and sand as much as pos-  
sible.  
Disassemble the stem and wipe it clean after use  
in sandy areas. When storing longer than about one  
month, remove batteries from the detector.  
Take advantage of Garrett's preventative main-  
tenance program. For a small fee, the factory will  
inspect the entire detector, replace its seals and pres-  
sure test it. Contact the factory for more details.

BATTERYꢁREPLACEMENT  
Figure 18  
Figure 17  
To access the battery pack, unscrew the battery  
cap at the rear of the detector housing by hand; DO  
NOT use tools. The o-ring should remain in the con-  
trol housing while the battery pack slides out. When  
installing batteries ensure that they are aligned with  
the correct polarity (plus and minus) markings. Re-  
install the battery pack by placing the contact end  
of the housing inside first and pointing downwards.  
(Figure 17.) Verify that the o-ring is well-lubricated  
and free from debris. Add a little silicon grease or  
petroleum jelly if necessary. Re-install the battery cap,  
hand tightening it until it is flush with the housing and  
the two index marks are aligned as shown. DO NOT  
over rotate. (Figure 18.)

DETECTINGꢁCODEꢁOFꢁETHICS  
Filling holes and obeying no trespassing signs  
are but two requirements of a dedicated metal detec-  
tor hobbyist. A sincere request that Charles Garrett  
makes to every user of one of his detectors is that  
each place searched be left in a better condition than  
it was found. Thousands of individuals and orga-  
nizations have adopted this formal Metal Detector  
Operators Code of Ethics:  
• I will respect private and public property, all  
historical and archaeological sites and will do no  
metal detecting on these lands without proper permis-  
sion.  
• I will keep informed on and obey all laws, regula-  
tions and rules governing federal, state and local  
public lands.  
• I will aid law enforcement officials whenever  
possible.  
• I will cause no willful damage to property of any  
kind, including fences, signs and buildings and will  
always fill holes I dig.  
ꢂꢃ  
 
• I will not destroy property, buildings or the remains  
of ghost towns and other deserted structures.  
• I will not leave litter or uncovered items lying around.  
• I will carry all trash and dug targets with me when I  
leave each search area.  
• I will observe the Golden Rule, using good outdoor  
manners and conducting myself at all times in a man-  
ner which will add to the stature and public image of  
all people engaged in the field of metal detection.
