Can a metal detector be set only to find gold
No. There are too many variations in alloy, size, thickness, etc. to be able to do just that. For example: A large piece of gold, will give a high tone and a high reading on the LCD discrimination scale, while a small gold nugget or piece of gold will read low on the same scale, as well as providing a low signal tone. The alloy in Karat (K) is also variable as: 9K, 10K, 14K, 18K, 22K, etc., in addition, there are: White Gold and Yellow Gold. Gold is mixed with copper, silver or platinum, will provide different views and signaling tones. And other metals with the same electromagnetic characteristics, such as, for example, Silver Paper and Aluminium winding rings from beer cans, could provide the same identification signals and display hits. Because of this, metal objects of Lead and Aluminium difficult to remove / eliminate. Even using the most advanced metal detector available on the market, it must be expected to dig up some scrap metal. But the better and more efficient discrimination, the more you increase your chances of making discoveries of gold items. Find your detector here
What is an Operating / Operation Frequency
Frequencies In connection with the metal detector referred to in kHz (kiloherts). This is the number of times the signal being transmitted and received by the detector every second. For example, a detector with operating frequency range of 6 kHz, the transmit and receive signal 6000 times in one second!, Or 50 kHz 50,000 times per second.
As a rule of thumb is: Low-frequency metal detectors provide a better sensitivity to copper and silver, and a better average search depth and separation capacity of scrap metal. The most common metal detect low frequency areas clean operating at around 7.5 kHz.
High frequency detectors or Multi Frequency Detectors (FBS and BBS) is more sensitive to very small objects, for example. Gold Nuggets (usually very small gold nuggets) But the downside is that they have difficulties to discriminate between non-magnetic metal alloy. (* This is NOT multi-frequency detectors to MINELAB) Anyway, these will have some difficulty in discrimination with non-magnetic metal. Most Gold Metal Applicants operating at very high frequencies (from 14 kHz to 80 kHz)
Are there any good places left to search
Oh yes. Just because an area has been searched by others, does not necessarily mean that there is no more left to find for those who are patient and search systematically over the area. To spend time on “Research” you can find productive places where there have never been searched. Seasonal changes in weather conditions such as: Stormer, Frost Periods, and erosion can also renew the previous crawl spaces. Especially include Salt Water beaches located on the open sea.
What can object identification Display (ID) or monitors do for me
Many models have a display, or LCD screens that show what you have discovered (Hypothetical only) This is in addition to audio discrimination. Once a signal of interest has been heard, the display will provide a secondary and independent interpretation of whether the detected object is good or bad origin. For this reason, you will dig less scrap objects with a Display Pager.
ID displays are in most cases a very accurate measurement and analysis of re-stan’s “Electromagnetic” origin. Unfortunately, many different metals that same electromagnetic origin (identity) target identifications increase your chances to unearth valuable items, while it reduces your chance to dig up scrap metal objects. If, and in a planned district, a special indication repeatedly show that you have discovered a scrap metal object, the repeated indications of the same type to be reliable, and these object’s signals can therefore be ignored.
What about all these various search coils? Do I need additional search coils
Standard coils sitting on the detector on delivery, is best suited to the All Round-tuning. A user can sometimes still want to use a smaller search head in parks and beaches, where the waste concentration is usually very high, as these heads insulates and separates the signals better than larger heads. Some search depth reduction must, however, are calculated. All the hard to reach places where it is impossible to use larger search heads, who in between three-and shrub roots, etc. A user may also wish to use a larger search head for Earth in Sskogen, and generally where large areas to be searched over, or he simply needed a larger search depth. Here are 15 “(38 cm) is recommended for exploration of objects relative to medium and larger objects, Norway Glass, cigar boxes or jars, in which jewelry or coins may be lying buried in them. Remember however that the sensitivity and the search depth to very small single coins and jewelry can be somewhat reduced by the use of large search heads.
