AIR TESTING
There may be times when you want to test or demonstrate the metal
detector without sweeping it over the ground, for instance if it's not
fully assembled, or if you're indoors. Place the searchcoil in a spot
where it's stable and more than two feet away from any large
masses of metal, including the reinforcing steel which is usually
present in concrete. If you're wearing a wristwatch or jewelry on
your hand or arm, remove it. Then, test or demonstrate by waving
metal objects ("targets") briskly several inches in front of the
searchcoil.
The Smart Trac ground balancing system cannot be tested or
demonstrated in air unless you happen to have appropriate
specimens of iron minerals or electronic ferrite available.
