Most valuable metal objects will send repeatable signals. If the signal
isn't repeatable, it's most likely a false signal. When there is a clear
sound demonstrating buried targets, you can read out the approximate
target type and depth on the LCD screen. And you might also move the
search coil above the target objects quickly, in order to get a more
stable signal.
5. Make use of the sound, to help discrimination
In the process of detection, you don't always need to watch the screen.
The sound identification system will sound three frequency tones to
help discriminate between targets.
• Low pitch 5￠nickel coin and so on.
• Middle pitch pull-tab, soda bottle lid and zinc coin.
• High pitch copper, aluminium and silver metal, such as 1￠,10￠,25￠
and so on.
6. Make use of the digital cursor, to help discrimination
The following table is used as a preliminary guide. The approximate
ranges of US dollar and pound sterling coins are listed in the table.
When detecting, there may be some difference in the number,
depending on the composition, size, shape, distance from the search
coil and speed of scanning. The surrounding soil also affects the
numerical value. There are differences in casting coins in different years.
The values in the table are only a reference. Gold has a wide numerical
range, a thin ring is about 45, and a rough ring and gold coin may up to
70-80.
