Metaldetector Gold Fish 2 is a PULSE-INDUCTION (PI) system which incorporates a large search coil (one meter by one meter as standard equipment) for the main purpose of finding large objects at great depths. These detection depths can almost be compared with those of magnetometers, which can detect nothing but ferromagnetic objects. Another great advantage of using the metaldetector GOLD FISH 2 together with the large search coil is being able to cover a large area in a short period of time. The actual search coil isencased in a square plastic frame (PVC tubing) and can be carried by one or two persons. Using the PI-principle offers some decisive advantages. First, the search coil is not part of a resonant circuit as it is the case with VLF detectors and can, therefore, be of almost any size and shape. This is absolutely necessary in order to increase the location depth considerably. In the second place there is a timely discoupling between the transmitting and the receiving phase which makes it possible to work with far greater transmission power. A further advantage is that small objects like bottle caps, pull tabs, pieces of aluminium foil, but also single coins are naturally rejected while using the large search coils.

But still the metaldetector GOLD FISH 2 is an easy-to-operate metal detector: you only have to deal with three simple controls, of which you need just one while normal operation. Objects are simultaneously indicated by a meter and by an audio signal which increases in frequency while approaching the object. The audio response has a very wide frequency range in order to avoid signal saturation when the search coil approaches a very close object. This makes it easy to pinpoint the exact location.



In general, the possible detection range will increase quickly with increasing target size. This is especially true for the PI-principle. But the electrical conductivity and the shape of the object are also important factors. Related to this, ferromagnetic metals take a special position. If these metals are exposed to the magnetic fields of a PI-detector, they will be momentarily magnetized. Although the electrical conductivity of these metals is poor and, therefore, the decay of the eddy currents is very short, the strength and the slow decay of the magnetization causes a strong signal. This is why PI-detectors are very sensitive to even small ferrous objects. The GOLD FISH 2 offers you the possibility of reducing the sensitivity to these objects (some smaller ferrous objects can even be completely rejected), while still being sensitive to most non-ferrous metals.

Brief summary of the advantages and capabilities of GOLD FISH 2 metal detector:

  • Operation is very simple and the internal adjustments are performed automatically each time the GOLD FISH 2 is turned on.
  • The PI-principle allows to enlarge the search coils and to use a high transmission power in order to achieve extraordinary detecting capabilities.
  • Using large search coils will allow the operator a fast search covering larger areas. Many different coils (various sizes and shapes) can be connected to the GOLD FISH 2 (1m x 1m is standard equipment):
  • The 28cm (12 inches) search coil is very effective for exact location and can also be successfully used in overgrown and bushy areas.
  • The 2m x 2m (80 inches x 80 inches) search coil covers four times as much ground as the standard coil and achieves even 30 to 40 percent more depth on large objects. However, sensitivity to smaller objects will be reduced. All search coils are waterproof and can, therefore, be used in shallow water.
  • Integrated systems for auto ground tracking.
  • Integrated systems for noise suppression.
  • Integrated system for auto tuning.

Detection Depths

The conditions while testing and recording the below objects were as follows: The SIGNAL (SAMPLING DELAY) was in position for maximum performance and a one meter by one meter coil was used. A clear increase of the ticking-noise had to be noticed. The largest surface of each object was measured.
Object Detection Range in Inches (Air Tested)
   
Object Detection range

Soft Drink Can (0.33 l)     Approx. 55" (140 cm.)
Iron Sheet 9" x 9" x 1/50"     Approx. 78" (200 cm.)
Fuel Tank 20 Liters (Iron)     Approx. 90" (230 cm.)

*Maximum detection range – 235" (600 cm)


These depths can be far exceeded when detecting larger objects. All mentioned detection depths may differ either positively or negatively when using reference objects of the same size, but possibly made of different alloys.
