Before attempting to use this product, please read this manual thoroughly and follow the instructions carefully. In doing so you will ensure the safety of yourself and that of others around you, and you can look forward to your purchase giving you long and satisfactory service. CONTENTS:
- Control Panel, A r m B r a c e , S e a r c h C o i l SPECIFICATIONS CODE OF ETHICS When metal detecting, here are some basic rules that you should follow. Always get consent of the landow ner before you search any site. Respect the rights and property of others and DO NOT trespass. Observe all national and local laws when you use the metal detector. DO NOT destroy historical and archaeological treasures or sites. Fill any holes that you have made an d leave the land as you found it. Only use the metal detector where safe to do so. Dispose of any rubbish that you find in a safe area, do not leave it for somebody else to find. Always follow procedures relating to fi nds as laid down in the Treasure Act 1996. See page 11 of this manual for information regarding reporting finds.
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com PREPARATION ASSEMBLING THE METAL DETECTOR 1. Remove the nut and bolt from the search coil. 2. Position the lower stem between the posts on the search coil and replace the nut and bolt as shown in Fig 1. 3. Adjust the search coil so that it is parallel to the ground and tighten the nut & bolt to lock into position. 4. Insert the lower stem into the upper stem See Fig 2. Press the two spring clips on the side of the lower stem, which will locate into the holes on the upper shaft. 5. Adjust the length of the shaft. When your arm is relaxed and the coil is just above the ground. 6. Wind the search coil lead around the stem and insert the connector into the jack on the control housing as shown in Fig 3. BATTERIES Only use alkaline batteries. DO NOT mix old & new batteries. 1. Remove the battery compartment cover from the rear of the control housing. 2. Insert 8 AA batteries into the batter y compartment. Make sure that you follow the polarity symbols inside the compartment. 3. Replace the battery compartment cover. Used batteries must be disposed of according to local regulations. DO NOT burn or bury used batteries.

6 SENS Used to adjust the
ground.
7 THRESHOLD Also used as a power
switch. The threshold should be tuned to the point where a faint tone can be heard.
3 VOL Used to adjust the
volume level.
8 LOW BAT Low battery indicator,
when this is lit.
4 TRACE Used to help pinpoint
a target. 9M O D E SELECTOR Discrimination (DISC) / All Metal (TONE). 5 PHONE Headphones socket. 10 METER In ALL METAL mode, the meter will show the signal strength. In DISC mode the meter will show the type of metal being detected
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com OPERATION HOW TO TURN THE DETECTOR ON OR OFF Rotate the THRESHOLD control clockwis e to turn the Metal Detector ON. Rotate the THRESHOLD control fully to the left to turn the Metal Detector OFF. DETECTION MODES There are 3 ways to detect metal using this metal detector. ALL METAL This MODE detects every type of metal and must be used when the material of the required object is not known. DISCRIMINATION This mode rejects some types of metal depending on the setting of the DISC/ TONE dial. At setting '0' the detector detects almost all metal. As you increase the setting more objects are rejected. On a high setting only the most conductive metals are found. NOTE: If the control is set too high, then modern coins are rejected. TONE The TONE mode discriminates between different types of metal with high or low pitched tones. SEARCH HINTS You must move the search coil from side to side in an arc approximately 15 cm wide. Do not swing the search coil like a pendul um, raising the sides. This will give you false readings. Sweep the search coil at a slow even pace.
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com USING THE METAL DETECTOR ALL-METAL MODE 1. Set the DISC/TONE dial (1) to the ALL METAL position. 2. Set the SENS dial to the middle position. 3. Hold the search coil 1 metre above the ground. 4. Hold down the TRACE button and rota te the GND BAL to the area marked 'P'. Then release the TRACE button. 5. Hold the search coil 2- 5 cm above the ground. If the pointer swings to the right rotate the GND BAL to the left slightly, If the pointer swings to the left rotate the GND BAL to the right. Each time you adjust the GND BAL press the TRACE button once. DISCRIMINATION MODE 1. Set the Mode Selector (9 ) to the DISC position. 2. Rotate the DISC/TONE dial (1) clockw ise away from the ALL METAL position. At setting '0' the detector will detect nearly all metal. As you increase the setting more objects will be rejected. On a high setting only the most conductive metals will be found. TONE MODE 1. Set the Mode Selector (9 ) to the TONE position. 2. Rotate the DISC/TONE dial (1) clockw ise away from the ALL METAL position. At setting '0' the detector will respond to all metals with a high pitched tone. On a high setting only the most conductive objects (such as silver) will respond with a high pitched tone. SENSITIVITY SENS adjusts the sensitivity of your metal detector to metal objects. If you turn this knob fully clockwise, it will be more sensitive to small objects and detect metal deeper down. However, if there are a high concentration of minerals in the ground it may give you false signals. THRESHOLD (DISCRIMINATION MODE ONLY) The threshold is the optimum point of tuning on a detector where a faint tone can be heard. By setting the threshold to this point the metal detector will be at its most sensitive.
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com USING HEADPHONES 1. Insert your headphones into the he adphone socket on the control housing. Connecting stereo headphones automatically disconnects the loudspeaker. Headphones give slightly more sensitivity as they reduce external noises which can interfere with your ability to detect objects. TROUBLESHOOTING FALSE SIGNALS If you are getting false signals from electrical cables, try to lower the sensitivity. The metal detector can give a false reading in areas which have a high mineral content. In this case lower both the sensitivity and the threshold and hold the search coil slightly higher than normal. ENVIRONMENTAL PROTECTION Do not dispose of this product with general household waste at the end of its life. This product contains valuable raw materials and should be disposed of appropriately at a recognized disposal facility. CAUTION: SET THE VOLUME TO THE LOWEST LEVEL BEFORE PUTTING ON THE HEADPHONES. THEN ADJUST THE VOLUME TO A COMFORTABLE LEVEL. CAUTION: CAUTION: DO NOT WEAR HEADPHONES WHEN OPERATING NEAR ROADS OR TRAFFIC.
