[. . . ] 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. For ultimate lightweight metal detecting the VLF-TR950-D control box can be removed and fitted to a belt around the body. [. . . ] The area on the scale around the control marked in green is the setting recommended for most ground target characteristics. The VLF-TR950-D is at its most sensitive with sensitivity adjusted to the point where a background tone is just starting to become apparent. Some detector users prefer to set sensitivity at a lower level than this so that there is no background tone. The presence of metal is indicated by the increasing intensity of the loudspeaker tone, accompanied by the LED which illuminates. This control is calibrated in the frequency of the detection signal (pulses per second). (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. 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. 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'. 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. It may be necessary to change to a different pulse frequency to avoid interference from extraneous signal sources. Experimentation with different metal targets will show you how the pulse frequency can affect sensitivity to different metals. When the detector gives a signal, move the search-head to the approximate area where the signal was heard, and reduce the arc of your sweep so that the search-head is just passing back and forth a few centimetres either side of the signal. Dig a neat hole by cutting around the signal position with a sharp edged trowel and remove a divot of earth which might now contain the metal object. Run the detector over the area again to see if the metal object is still in the hole or in the piece of earth which you have just removed. [. . . ] Dig some more and sift through the earth until you find what you are looking for. (recovering finds in sand is very much easier with a sand scoop - a trowel like a sieve where the sand is able to run out leaving the find in the scoop). The use of headphones will increase battery life and make it easier to discern faint signals. Do not touch anything you suspect might be live ammunition - inform the police. [. . . ]
