‘Flat top metal detectors’ is an outdated way of describing
the shape of metal detectors. Technology has advanced way past the need
to describe a metal detector by it shape. The shape is not even as important
as knowing how your equipment matches up to your metal detection goals.
Those who are new to the hobby of working with metal detectors may
not know much about how things like flat top metal detectors work. Although
the functions metal detectors perform are fairly simple, their operation
is not.
• Initial test - The step when searching for metal is a couple
of tests. One way to do a test is to take a couple of coins, throw them
on the ground and then see how well the detector is working as you scan
over the coins. If the beeper and light work, you know that you are
ready to start searching.
• Send a signal - Once you get started searching for real, the
metal detector will send a signal into the ground. This is done on a
regular basis over and over. It is not so much that the detector only
works when it fids metal. Rather, the detector simply works differently
when any kind of metal has been picked up.
• Hear or see the detection - When the metal that is around or
under ground has been detected, the steady stream that the detector
has been sending is interrupted. This means that there will be a difference
in the way the light lights up. It also means that there will be a difference
in the sound that the detector might make.
Flat top metal detectors are often used at places like forests and
beaches. So the next time you see someone using a metal detector near
you or if you get a hankering to use one yourself, you already have
a solid basis of knowledge about how these items work.
