Atari Adventure Reboot. ] CS1220XD - RAPID GET YOU GOING INSTRUCTIONS Assemble and adjust for length (Twist surplus lead around stem). The meter will indicate in the right hand green sector if the batteries are OK. With the search head 1-2 cm from the ground, press and hold the RETUNE button (lower mid) and adjust the TUNE control until a tone is just heard. If the tone drifts from the threshold position press the RETUNE button to reset the level. ] If however, the detector is being operated in the Discriminate Mode on an inland site, it will be necessary to balance the sensitivity level to reduce the ground effect.

In practice this means setting it to the highest level possible, which of course will depend on the degree of mineralisation, and how capable the operator is at keeping the search head level with the ground. A sacrifice in sensitivity level will drastically reduce the ground effect, but will not reduce the depth penetration to the same degree. For example, by reducing the sensitivity level from full to midway, ground effect will be reduced by 80%, but depth penetration will only be reduced by about 20%. Discriminating When used in the Ground Mode the CS1220XD will detect all metals and will not discriminate.
However, in the Meter Disc and Meter Audio Disc Modes the CS1220XD has been programmed to operate at a fixed discriminate setting. It is recommended that all objects that are not rejected should be recovered, i. If the meter needle does not dip or the audio pitch is inconclusive, then find the object. Iron, unlike a coin, occurs in a multitude of shapes and sizes and as a result it is possible that large pieces of iron may give a positive reading. Iron in the shape of nails or pieces of wire also may be present on the surface of a site. Anomalies or confusing signals can occur in the first few inches away from the search head, and are typically characterised by a double signal from the same object, usually iron, which often ranges from a strong positive to a strong negative signal.
To overcome these problems simply raise the search head, retuning if necessary, and rescan until a clear signal of rejection or acceptance is obtained. 13 Detection Range Your CS1220XD is a top performance detector but adverse soil conditions can significantly reduce the depth of detection. Detection ranges will vary depending on the size of the object, the length of time an object has been buried, and the type of ground the object is buried in. The best ground conditions are well compacted soils and coins can be found at the greatest depth if the object has been buried for some time and the coin has interacted with the salts in the ground, thereby appearing larger to the detector. The worst conditions for detecting are on loosely compacted or freshly dug ground or when the object has only recently been buried. Determining the Target Size and Depth An operator who is familiar with his instrument will be able to do an excellent job of determining object size, shape and depth before he digs.
This technique is learned from careful analysis of the meter and audio signal coming from the detector. 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. After digging up the object, compare the object size, shape, depth and position in the ground with signal information you received before digging. Msr206 Encoding Software. After careful analysis of many signals you will learn to 'read' the hidden target before digging. Detecting To test for the type of signal you will get, take a coin or metal object and with the detector set up on a table tuned as previously described, move the metal object towards and across the search head.
