User manual C-SCOPE VLF-TR950-D

[. . . ] metal targets give an audio signal from the loudspeaker accompanied by illumination of the LED indicator . maintain a steady sweep speed swinging the search-head from side to side with an easy motion. When you encounter a signal, identify the precise target position by reducing the width of the sweep arc until it is just a few centimetres either side . Keep the searchhead moving. 3 the controls and at they do 1) Control box mounting clip. [. . . ] This control is calibrated in the frequency of the detection signal (pulses per second). The recommended setting is within the green zone on the scale. (A metal detector is a type of radio receiver in its principle of operation and may be subject to interference from, for example, overhead power lines, transmission masts and even other detector users in the near vicinity. The pulse frequency control gives the possibility to change the operating frequency to an area free of such interference). Other pulse frequency settings, within the red zone on the scale, can be used in treasure hunting applications but they tend to be insensitive to thin section non ferrous objects. As many valuable objects fall into this category, we do not recommend the use of these frequency settings. When the battery check switch position is selected (red battery symbol), the detector will emit an audio tone proportional in length to the condition of the batteries. A tone of 1 - 2 seconds duration indicates good batteries. No tone indicates that the batteries should be changed. embling the VLF-TR950-D The stem height adjuster should be slackened to allow the lower stem to enter the upper stem section. The search-head lead may then be wound around the stem as shown in the photograph. A search-head lead which is not well secured to the stem could move about causing false signals. Keep the search-head parallel and as close as possible to the ground right across the arc of the sweep. The use of a searchhead cover protects the head from abrasion damage caused by friction with the ground. Search your chosen site carefully by moving forward only the width of the search-head at each sweep. Move up and down the search area in lines about 75 cms apart so that there is plenty of overlap in the ground you have covered. Search with the sensitivity set as high as possible according to the ground conditions. On the majority of inland sites the recommended sensitivity setting (green area on the scale) will give the best results. `Some severe ground conditions, for example mining areas containing mineralised deposits, may give rise to false signals and the sensitivity level should be reduced to a point where detector operation becomes stable. Some detector users prefer to set the sensitivity control at a point where there is no background tone, sometimes called `silent search'. (Sensitivity control set around the start of the green zone). With the detector set like this it is more noticeable when a target signal occurs. If the detector is set at maximum sensitivity (Sensitivity control set at the end of the green zone) there will be an audio tone constantly in the background and a metal target will be registered by an increase in the intensity of that tone. 6 We recommend a pulse frequency setting within the green zone on the control scale. [. . . ] Do not touch anything you suspect might be live ammunition - inform the police. Do not take your detector on any scheduled historic site. If you find anything which looks like it could have historical significance, report it to your local museum. Acquaint yourself with any laws relating to the use of metal detectors if you want to go detecting in countries other than the UK.
