[. . . ] · . =~©®fF>t!: METAL DETECTOR/TREASURE SEEKER VL~TR1200B OPERATING INSTRUCTIONS INSTRUCTIONS VLF. TR 1200-8 INTRODUCTION IMPORTANT To protect your investment complete both sections of the guarantee at the back of this instruction manual and return the reply-paid portion to C-Scope. This is particularly important in order to obtain the free second year parts guarantee. In the event your detector should ever require service this package will be most suitable for postal protection. C-Scope detectors are recognised as the finest metal detectors available. [. . . ] However to optimise on the range of the detector and its analytical abilities, follow this procedure: (1) (2) (3) (4) After receiving a target response when sweeping note exact location of target. Place the search head on the ground and retune the detector by operating the ADC switch. Keeping the search head on the ground sl ide the head back over the target object. This method should increase the meter response because the search head is nearer to the object, the detector is at its optimum tuning level, and ground effect cannot interfere with the meter channel because the gap between the search head and the ground is constant, i. e. The meter channel is set at a level which guarantees that there can be no loss of depth or response to silver, copper or gold objects, however small or thin in section. Because response to these objects has been taken as the overriding priority the detector will give a positive response to pull tabs, or even large pieces of silver paper. A higher level of discrimination can be obtained by operating in the G-D3 mode. However, operating at Discriminate levels beyond Mode D2, Discriminate Level 5 may result in depth losses on certain objects such as cupro-nickel or thin section jewellery. The Discriminate level of the meter channel which is fixed as previously described is equivalent to Mode D2 Discriminate Level 5. OPERATING IN THE ANALYTICAL MODES To operate in one of the three analytical modes: G - D1 G - D2 G - 03 , it is necessary to decide which level of discriminate is requirea4'or' the site you wi:-: :':"J. For instance, or a ploughed field where silver paper and ring pulls are not a problem the user will probably select G-D1. On another site, say a picnic si~e where silver paper and some ring pulls abound, the user will probably select G-D2 or even G-D3. Follow steps 1-3 "Setting the Tuning Level of the Detector" and then se!ect the most suitable mode by following this procedure: 4b. Keep at a steady height above the ground and ensure the Tuning Level is set correctly by operating the ADC switch firmly to the left or right and then release it. The principle of the Analytical'Moce operation is to search in the Ground Exclude Mode (Gl and then analyse any target by switching to the relevant Discriminate Mode (D). To select the (G) mode press the ADC switch to the left and then release it. When a target object has been located, note the location of the signal and take the search head away from the object at least two to three feet. Select the (D) mode and ensure the tuning level is at the correct level by pre~sing the ADC switch to the right and then release it. Carefully rescan the target object, ensuring that the search head is kept level with the ground. :C;b. 6 9b. 11b. To analyse the find: a rejected object will give a swing to the left on the meter and a decrease in audio response; a worthwhile target will give a swing to the right on the meter and an increase in audio response. The Discriminate Level may be fine tuned in each of the three main D modes by varying the Discriminate level control. The Sensitivity Level may be varied but 0 is the recommended level in the Analytical Mode. OPERATING IN THE DISCRIMINATE MODE On a wet salt beach it is best to operate in a Discriminate Mode all the time. and to ground exclude in these conditions the detector needs to be set at a point where iron is rejected. This is a useful coincidence because it means that ground exclusion and discrimination against iron are possible at the same setting on wet salt sand with the 1200-8. [. . . ] (5) Old fords or bridges. (6) Areas exposed at low tide where eddy action has been taking place. Tidal rivers are partic;ularly interesting, as once you have found a good site or spot where coins have collected due to the currents, you can search the area well one day and still return at a later date for more rewarding finds. Rivers tend to sort out their load and distribute it according to weight along the bank in places like those itemised above, Beacluls Beaches are, without a doubt, the favourite haunt of the average British metal detective. At one time or'another, almost everybody has made the journey to the coast. [. . . ]
