1. beep sounds 6 If needed cross sweep the target in X pattern at different angles to zero in on the exact spot on the ground at which the beep sounds COIL MOVEMENT When swinging the coil be careful to keep it level toned with the ground about 1 1 5cm from the surface de Never swing the coil like a pendulum Raising the search coil while sweeping or at the end of a sweep K i Sp will cause false reading When searching its better you sweep the search coil from side to side in an arc line of 7 8cm motion Swing the search coil slowly overlapping each sweep as you move forward It is important to sweep the coil at a consistent speed over the ground as you search After identifying a target your sweep technique can help in identifying both the location and the nature of the target If you encounter a weak signal try moving the coil in short rapid sweeps over 15 the target zone such a short rapid sweep may provide a more consistent target identification Most worthwhile objects will respond with a repeatable tone If the signal does not repeat after sweeping the coil directly over the suspected target a few times it is more than likely trash metal Crossing the target zone with multiple intersecting sweeps at multiple angles is another way to verify the repeatability of the signal and the potential of the buried target To use this method walk around the target area in a circle s2. Within a geographical area ground conditions can change Varyingelevations proximity to water and concentrations of rock sand or clay can all affect ground condition and sometimes require recalibration with the ground balance knob 5 5 PINPOINTING non motion mode Coil sweep technique is not important in this mode Rather user retuning is critical The detector does not automatically adjust to changing ground and environmental conditions the operator is required to make the adjustment RETUNING 17 Keep the coil still just above the ground surface and press the GND TRAC button Make sure that the spot on the ground you chose for tuning did not contain metal pass over the area with the coil again to insure that the detector does not emit a tone Detection Field The detection field depends on the size of the target Large Objects After detecting a target LCD displays sensitivity level and speaker beeps If lift the coil off the ground to a distance around 2cm the tone does not fade you have detected a large or irregularly shaped object Further lift the coil off increments on LCD decreases obviously and the sound of beeps reduces rapidly Outline the object with slow coil movements at the same height Small Objects After detecting a target LCD displays a low sensitivity level and the speaker emits a faint sound While maintaining the coil at this height above the ground move the coil from side to side Note the spot wher

5. The Most Advanced Metal Detector This metal detector is a professional metal detector As a sophisticated electronic device the most difficult aspects in metal detecting have been automated If you are fresh in using metal detector we highly recommended you 1 Set the sensitivity to a low level in the event of false signals Always begin at a reduced sensitivity level when using After you have become familiar with the detector you may try it at full sensitivity 2 This detector is for outdoor use only Do not use indoors Many home appliances can emit electromagnetic wave and will interfere with the detector For indoor testing turn the sensitivity down and keep the search coil away from facilities such as microwave ovens computers and TVs If your detector beeps erratically turn off the electronic appliances and lights especially those with dimmer switches 3 Read this manual Most importantly review the BASIC OPERATION P 8 CONTENTS Terminology 25 2 sexs ea ee ee ee Re Bee A 3 Assembly 24024 2cnw eves e RE ERE Sede ieee sal 4 ControliPanel ele Sette Ad a OEE nx 6 Basic Operation occid eee et LR x ed a 8 In the Field Technique Lslllssseeeeessess 13 Care and maintenance cece eee eee eee 19 1 TERMINOLOGY The following terms are used throughout the manual and are standard terminology among detectorists ELIMINATION Reference to a metal being eliminated means that the detector will no
