User manual C-SCOPE VLF TR 2200-3000 ADC

[. . . ] The ground effect in the discrimination modes is minimal on most sites but should it become intolerable the operator can reduce the ground effect by reducing the sensitivity. The C-Scope VLF TR 2200-3000 ADC is a professional model and is manufactured to the highest standard to give you the maximum performance. The machine has been designed for easy operation, but there are several ways of using the detector. In order to get the best out of your machine and ensure correct operation it is important to spend some time before going out with your detector studying these instructions. [. . . ] If a small iron nail is now brought near the head the sound will disappear. Some adjustment to the size of the iron objects that will be rejected in this way is possible by pushing the auto-tune button and turning the reject control. Silver paper is not rejected on D1 but it is on D2 as are larger iron objects. D3 rejects most kinds of 'junk' with suitable adjustment of the reject control ring-pulls can now be rejected. But some useful objects are also rejected, so use D3 with great caution. On dry sand this may not be a problem but on other soils ground effect may give false indications of objects. To minimise this problem proceed as follows: - Use the smallest amount of discrimination which wi II work on the site. - Set the tuning with the head held at the normal search height, e. g. , an inch above the ground level. The detector sti II operates even with sensitivity set to 0 and ground effect is reduced. For information, detection range is halved if this sensitivity control is rotated fully from maximum sensitivity to minimum sensitivity. Accordingly, only reduce sensitivity as far as is necessary to overcome ground effect. GROUND ELIMINATION When using the detector in the normal mode, ordinary soil has little effect when the ground control is as 5. It does not matter which connector goes to which battery so long as it is connected correctly). OPERATING NOTES In the normal mode ordinary soil has very little effect. Indeed, it can be made to have no effect at all, by means of one simple adjustment which you will quckly learn to carry out. Once the ground has been 'eliminated' in this way you will find that there is no change of sound as the head is lowered towards the ground or raised from the ground. The only thing that affects the sound is buried objects capable of conducting electricity. In general this means metal of any kind - copper, iron, aluminium, silver, gold . The one disadvantage of the normal mode is that it does not discriminate between metals - though it does perform the useful job of discriminating against the particles of iron ore which permeate some soils and can cause false indications with some detectors. Such 'mineralised' soil can be 'tuned out' in the normal mode just like ordinary soils. Learning to 'tune out' the ground is excellent practice in preparation for getti ng to work on the D modes. Here the detector reacts according to the nature of the target object. obje. £t is a tinplate bottle cap, a piece of silver paper, a cigarette packet, an iron article, a ring-pull, but will sti II sound out when the object is a coin. The price paid for this is that the detector now becomes sensitive to the ground. [. . . ] Each time a signal is heard, listen for any peculiar characteristics it may have; determine over how large an area you get a detector signal, and try to "outline" the object before you dig, Listen for the sharpness or dullness of the signals and determi ne the magnitude or strength of the signal. After digging the object compare the object size, shape, depth and position in the ground with signal information you received before digging. After careful analysis of many digs, you will learn to "read" the hidden target before digging.
