2 Metal detec tors create an elec tro - magnetic field, which p enetrates the ground. Because metal is c o nductive it causes a change in this f ield. T he detector senses this change and sends a signal back to the control box, aler ting the o perator . Metal detec tors can determine the size, shape and composition of metallic objec ts beneath the [...]

12 13 It is best to only turn the detector on, when outdoors, away from sourc es of elec tromagnetic disturbance. There are many metallic objec ts inside a house (e.g. nails in the f loor , reinforcing in the walls) that migh t overload the electronic s of the detector . There may also be int er ference from T V sets and other household ap pliances[...]

14 15 T o hold the detec tor , thread your arm through the armrest and strap. Grasp the handle of the detector and rest your forearm in the armrest. Y o ur elbow should sit just above the top of the armrest. Lightly tighten the velcro strap and secure it around your arm. The correc t position of armrest and length of shaf t should allow you to swin[...]

17 Ta r g e t R e s p o n s e (Metal Object Response) This is the sound given by the detector when a target is located and not discriminated (rejec ted). In Coin & T reasure Mode, a target that is highly conductive (e.g. a large silver coin) generally causes a high tone beep and ferrous targets generally cause a low tone beep. In Prospec ting M[...]

18 19 19 18 PR OSPECTING MODE Coin & T reasure Mode is used for detec ting valuable objec ts, including old and mo dern coins, jeweller y and ar tifac ts . Undesired objec ts such as pull-t abs and bottle c aps may be rejected . This mode can be used in a variet y of environments, such as park s and salt water beaches. The numerals ( T arget ID[...]

21 Buried metal objec ts are re ferred to as targets . T arget signals contain ferrous and conductivit y information. As the coil is passed over a target, the detector digitally processes the target signal and displays this as a number . T arget Identif ication ( ID) is used to distinguish one t ype of metal t arget from anothe r . T arget ID numb [...]

22 The X- T erra 70 has an All Metal Pattern, three preset Discrimination Patterns and Iron Mask. The combinations of ac cepted and rejec ted segments are referred to as Discrimination Patterns. The X - T erra 7 0 has preset Discrimination Patterns that hav e been cus tomised to detect general desired target s, such as coins and jeweller y . Patter[...]

25 24 The Preset Discriminatio n Patterns may be edited to create custom patterns. Method 1 - to reject a specific T arget ID using an actual target When detecting a target, a discrimination segment will f lash, indicating its position on the discrimination scale and the target ’ s ID number will appear on the LCD. Press ACCE PT RE JEC T to rejec[...]

The X- T erra 70 updates the T arget ID and Depth whilst Pinpointing in Coin & T reasure Mode. PINP OI NTI NG 26 When a signal is heard, it is an advantage to identif y the e xac t position of the t arget. This is determine d by using PINPOINT . Enabling Pinpoint instructs the X- T erra 70 to temporarily disengage discrimination and become a no[...]

28 29 Dete ct ion (d isplay st ate) In Coin & T reasure Mode, the T arget ID, discrimination segments and depth automatically translat e target signals. The last detec ted T arget ID s tays on the display until another is detected. If the detec tor passes o ver a target that it rejec ts, the display will return to a detection screen represented[...]

30 31 The X- T erra 70 is highly sensitiv e and has a wide Sensitivity adjustment range. It is impor tant to set the correct Sensitivit y level for your detecting conditions. Sensitivity is the detec tor’ s level of response to a target and its environmen t. Real targets are indic ated by distinct b eeps. Inter ference or false targets are interp[...]

32 33 V o lume is the level of sound emitted by the detector when a target is detec ted. The Volume c ontrol limits the ma ximum volume of target signals. The sound produced by a distant target star ts sof tly . As you get closer , the volume level increases rapidly until it reaches the maximum level that has been set . The sound produced by the de[...]
