 1m x 1m (2 windings) universal cable coil 8 m perimeter

The universal cable coil has to be arranged to a 2 winding search coil and has to be fixed on a 1m x 1m PVC- tube frame for example.

Searching with the 1m x 1m frame coil is mainly advisable when looking for hand sized or bigger metal objects buried deep while ignoring small coins, nails and pieces of foil at the surface of the ground. The possible detection depths with this particular frame coil are very high compared with standard sine wave VLF-TR-detectors. This is one of the reasons why this particular search coil is used for most professional applications. Large areas can be covered in a short time. Best results are achieved with metal objects having a surface of at least 10cm x 10cm. Because of the size of the coil most of the small metal fragments will be ignored. However bigger nails can be identified with the conductivity/ time delay target identification. Most of the nails and other metal fragments can be easily eliminated by increasing the distance between the search coil and the ground. Even at distances of 50 cm or more there will only be negligible detection depth losses when locating large metal objects. This frame coil has to be carried by two persons with carrying straps.

The high depth range of the 1mx1m frame coil is achieved with intense and therefore deep going magnetic field transmitted. The detection depths listed in chapter 11 have been recorded with different DEL Delay and GND Ground settings. In some cases detection depths in wet, conducting ground are slightly higher or lower than listed.

For even higher detection depths use the 12m cable coil which can be arranged similarly to the 8m cable coil to 1m x 1m, 1,5m x 1,5m or 3m x 3m.

2m x 2m frame coil (1 winding) universal cable coil 8 m perimeter

The 8m universal cable coil has to be laid to a single turn on a metal free frame and has to be fixed with tape for example. This particular search coil covers four times as much ground as a 1m x 1m frame coil does. It should only be used when searching for metal objects with a surface of at least 20cm x 20cm pointing towards the coil. Smaller targets will be located less effectively than with a 1m x 1m frame. This is mainly because it will become more difficult to pinpoint those smaller objects with the large coil. The maximum detection depth is very high and can only be increased with the 12m cable coil arranged to a 1,5m x 1,5m or 3m x 3m frame. The 2 m x 2 m frame coil can be carried by two persons without any carrying straps at a distance of about 80cm above the ground. This is particularly useful when trying to ignore medium sized metal objects which are smaller than a horseshoe for example. Coins and nails will no longer be detected when doing this.

The 2m x 2m coil acts as a large aerial for medium wave transmitters. Therefore smaller frames like the 1m x 1m coil will be of better choice when working in urban areas. The next coil described will be less sensitive in general but won't suffer from electromagnetic interference of transmitters, power lines.
