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 15 13 Discrimination Adjustment Used to set the desired level of discrimination Figure 15 The following procedure shows how easy it is to operate the Infinium LS BASIC OPERATING INSTRUCTIONS 1 Turn On Battery Test 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 2 Selecting Automatic Ground Track Setting 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 14 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 groun2. 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 20 Pinpointing with Mono Searchcoils 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 9 Adjusting Frequency 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 thresho

10. ductive 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 27 DETECTOR MAINTENANCE Your Garrett detector is a sensitive electronic instrument It is built to withstand rugged treatment in the outdoors Use the Infinium LS to the ful
