Each sweep should overlap the area covered by the previous sweep. This will ensure a full coverage of the searched area. Be aware of the search pattern of the coil and overlap your sweeps to take this into account.
7.2Prospecting Tips
The SD2100v2 has superior ground balancing features and is possible to find quite large objects near the surface in
Large variations in the mineralisation of an area can produce a signal in the detector. Typically, in the Victorian goldfields you might get a response from a concentration of orange/reddish ‘dyke’ material or clay. Similarly, in the loamy conditions of Western Australia a pocket of dark orange/reddish clay or rock may produce a sudden signal variation.
It is not recommended that you try to ground balance the detector on top of a signal in an attempt to cancel a questionable response, as this can also cancel weak signals from very deep targets. If in doubt, scrape away some soil above the suspect signal. If the signal gets stronger, it is a target, so dig it!
If the ground is extremely variable and causes the detector to be very noisy, you may try operating with the Search switch set to the Balance 1 position. This will reduce noises caused by the varying mineralisation, but some nuggets may not be detected. The full range of nuggets are only detected when the Search switch is set to the central Search position, not in Balance 1 or Balance 2.
Charcoal can sound loud at times and rather like a metallic object when close to the surface. Charcoal is usually created by bushfires or by farmers burning off tree stumps. The charcoal may be below the ground level and is not always obvious until you have actually dug up and located the cause of these noises a few times. Once the charcoal is removed from the ground the signal will vanish.
