measurement to another, i.e. this time is needed to move the device to the new
location, treat the soil with water, prepare the device, etc. If you want to check
the same place for other type of metal, then, after looking for silver for example at
8.7 to 8.9k Hz, you do not need to take out the probes:
• Turn the power off.
• Wait for 15-20 minutes.
• Remove the probe cables from
LRL3000D
• Turn the power on.
• Adjust for gold search, for example, at 5 to 5.6k Hz.
• Connect the cables to the locator and wait for at least 100 seconds again, which
is equal to approximately 100 meters of processed area, and start searching.
• These 15-20 minutes of rest are required to clear off the previous frequency on
and at least 100 seconds for the newly transmitted frequency. If you have not
changed the operating frequency and only triangulated at 90 degrees, you will
find a new crossing point with the new measurement. If you draw an imaginary
line between the locator, the new point and the marked line from the previous
measurement, you will see the location of the potential object (see
Fig. 3
). That
is not all. Make a few more measurements on the established location to
determine the size and depth of the buried object. Pay attention to
Fig. 6
. It
shows that there is a crossing in point one, a second crossing on the object, and
a third crossing in point two. The way of studying the object is described in detail
around
Fig. 6
.
