Additional Applications

1.

The military and many local and state police departments use the GA-52Cx to detect

buried ordnance and discarded weapons.

2.

People drilling in an area where hazardous materials might be encountered use the

GA-52Cx to search the area prior to drilling. Other Schonstedt magnetometers are

available that can be lowered down the hole for periodic checks as drilling progresses.

Other Notes

1.

A burbling sound indicates the presence of an energized power line.

2.

The instrument will not detect non-ferrous metals, such as gold, silver, copper, brass

and aluminum.
